How can I find out if my car has an immobilizer?

When buying a car, the new owner does not always know whether it has an immobilizer. And if so, does the device work? A crawler may be installed. It is also possible that the device is broken and does not perform its protective function. Is it possible to check all these points to know how things really stand with the vehicle blocker?

@mototeam.com.ua

Tell me, how can I find out if the car has an immobilizer?

Such a situation that I found out about installing an alarm system and its installers add 2 thousand to the cost to bypass the immobilizer. I have a 2004 Chevrolet Lacetti. How can I find out if I really need a lineman or if they want to scam me out of money? Is there any way to check if I even have an immobilizer?

My first thought is to try to start it with the left key.

Remove the battery from the key, if it doesn’t start after that, it means there’s an immo

Make a duplicate from the Chinese and try to start it with a duplicate, if it starts, it means no

What does the battery have to do with it?

1. Look at the key - is it original or not? 2. If it’s not the original and the car starts, there is no immobilizer 3. If it’s original, you make a copy and try to start it))) If it starts, see point 2, and if not, then there is an immobilizer

Another option is to do a full decryption using the VIN, it will be indicated there. Z.Y. Where did the Opel go?

Is it possible to read the package contents of this lacheta?

I agree, the battery doesn’t matter for the chip. I crumple the keys with chips, but they are sealed tightly. TS, make a duplicate, it’s still advisable to have it.

My key, as the seller said, was hidden somewhere under the panel. )

The Hateful Six! Toev Ark. 97

The constantly flashing shift light reminds me of immo)))

The key is always hidden under the panel! and two keys are given to you when you buy a car :)

Exactly. And if it’s immo, then the relative will still be buried in the “Crawler”, which costs 250 rubles. And a duplicate will become necessary.

AAAAAAA, it works)))))))))) On the Lacetti forum I read a test method)))))) You need to wrap the plastic part of the key in foil. In this form, the car with immo will not start. With the key wrapped in foil from a pack of cigarettes, my Old Man really sent me to hell, it didn’t start))))))))))))))

what 2 tr. a lineman costs 200 rubles!

oh, the namesake already wrote)

there is immo on the car. Do you need either a lineman to warm up, or leave the key in the car?

what 2 tr. a lineman costs 200 rubles!

oh, the namesake already wrote)

Fuck it's 200 rubles.

there is immo on the car. Do you need either a lineman to warm up, or leave the key in the car?

Fuck it's 200 rubles.

Come, I’ll sell you a new one for 200 re

At Lachet, you can pick out the chip itself from a key with buttons, stick it next to the lock and there’s no need for a crawler. The Tokma stops starting with the second chip key))))), you still have to sharpen the blank and drive with it. And using the signal to break the immo receiver circuit.

It is enough to install a whitefish that will be friends with the car via the CAN bus and there is no need for crawlers or hidden keys, much less overpay for bypassing the immo.

Diagnostics for immobilizer problems

Before repairing damage to the blocker, you must perform the following steps:

Charge the battery. If the battery is discharged, the immobilizer may not work correctly. If the battery is low, it must be removed and recharged using a charger.
Use the original key. The main control element should be the one recommended by the manufacturer.
Remove the ignition key from the switch and try to find the problem with it.
Move all electronic devices and gadgets away from the control unit. The blocker is an electronic device, so the presence of the same devices nearby may lead to interference. If, after the devices have been removed, the operation of the immo has stabilized, then the device is in working order.

What are the signs of a breakdown?

“Symptoms” by which you can determine that the immobilizer is broken:

the starter does not turn when trying to start the engine;
the starter rotates the crankshaft, but the power unit does not start;
on the dashboard in the car, the immo failure indicator lights up, the Check Engine light may appear on the control panel;
When you try to lock or open the car door locks with the key fob, the system does not respond to the actions of the car owner.

The 100 Video Inc channel talked about one of the malfunctions in the operation of the internal combustion engine blocker.

Main causes of malfunction

Causes of immo malfunctions:

The battery was disconnected from the car's power supply while the ignition was on. If the control module is tightly bound to the control key, as a rule, malfunctions do not appear for this reason.
The battery was discharged when trying to start the power unit. If there are problems with the engine when cranking the starter, the battery will quickly run out. This problem often appears in the winter season.
The problem is sometimes associated with replacing the car engine or microprocessor immo control unit. When buying a new engine for a car, you need to purchase a kit to control the power unit. This refers to the central unit, immobilizer and key tag. Otherwise, you will need to bind the control element to the microprocessor module.
Malfunctions related to the operation of electrical devices and instruments. For example, the fuse that protects the immobilizer electrical circuit could fail.
Software failure. Immobilizer coding information is stored in the EEPROM circuit. This board element belongs to the ROM class. If used for a long time or if software problems occur, the firmware will fail and the circuit will need to be programmed again.
Failure of the tag key. Inside the device there is a chip that is designed to identify the car owner with the immobilizer control unit. If the tag breaks down, you will not be able to diagnose it yourself; this requires special equipment.
Poor contact between the receiving device and the antenna. The appearance of such a malfunction is usually caused by shaking. Perhaps the pads on the antenna module and receiver were made poorly, which led to oxidation of the contact elements. Sometimes the problem is a dirty connector. The contact may not disappear immediately, but after a certain time.
The battery in the key is low. The key can be equipped with an autonomous power supply system, in which case its performance is not determined by the battery charge.
Damage or breakage of the pumping loop. The electrical connection to this element may be broken.
Malfunction of the electrical power circuits of the engine blocker control module.
Loss of communication between the immo module and the central unit of the power unit.

How to find an immobilizer - where is the IMMO located?

Happy owners of cars with an immobilizer (IMMO) may not be interested in this article. But it will strengthen the confidence that sound sleep and confidence in the safety of a car standing unattended is a merit of IMMO. These lucky ones sometimes don’t know where the immobilizer is. But the fact that it is there reminds them of the indicator on the instrument panel, the chip key and the personal tag.

Car alarm and immobilizer - unity and contradictions

How does it work

Innate curiosity or an irresistible thirst for creativity
Where is it located during standard installation?

Those car enthusiasts who do not yet believe in the miraculous power of IMMO or doubt it will find it useful to learn about its capabilities. Find out what is hidden behind the English “immobilizer” and the unfriendly Russian – immobilizer. This faithful sentry is constantly in the car and begins to serve when there is no one else to do it. Any action in the car that IMMO does not understand is perceived as hostile.

Car alarm and immobilizer - unity and contradictions

The immobilizer in no way opposes itself to the alarm system. There is no duty to frighten potential intruders with the terrifying roar of a siren and fireworks of light flashes. A standard installed IMMO operates secretly for car thieves. He will even let them start the car and drive away. But the result will be the same - the car will be immobilized in the wrong place.

The main task of the device is to recognize the owner among thousands of others and allow him to use the car. Otherwise, no matter who gets behind the wheel of the car, he will not be able to use it. The defense has many options to find out the owner:

according to a pre-written code, dialed on a remote control located inside the car;
if the driver has a tag with a built-in chip. The tag, in the form of a bank card (by size) or key fob, can be located separately from the keys and documents for the car;
when the driver inserts the chipped key into the car's ignition switch;
by the fingerprint of the car owner.

Important: the place where IMMO is located is also the secret of its general, secret mission. Although the place where the regularly installed devices are located is often unknown only to the owners.

Recommendations for use

To avoid problems with the immo, you should adhere to the following recommendations:

The owner of the car must have a spare key. If a problem arises in the operation of the chip on the key, you can unlock the immo with an additional key fob. If a spare key is not available, one must be made.

The unlocking tag should be kept away from other keys, this will reduce the likelihood of unauthorized entry into the car and starting the engine.

A high range of the key can be achieved as a result of its location along the plane of the transceiver.

The car owner must know which immobilizer is installed in the car. It is advisable to understand the principle of operation of the blocker so that when the first symptoms of problems appear, you can solve the problem yourself.

Remember that when using a non-digital blocker, a blinking diode indicator is considered the main sign when detecting a control module.

If the installation of the anti-theft device is carried out by specialists, then the car owner must agree with the specialists on the installation location of the lock.

How does it work

If the car has a standard installed immobilizer, then it constantly waits for the coded password addressed to it. He can receive it in both contact and non-contact ways. In the first case, this happens when you enter a secret code or when you turn on the ignition with a chip key. In the second case, when a standard installed IMMO itself detects the driver’s personal tag.

With each of these options, he analyzes the received password with the data that is pre-registered in his memory:

if there is a match, IMMO, which can be located anywhere in the car, transmits the results of the analysis to the ECU (control unit) of the car;
The ECU, having received the IMMO signal, unlocks the corresponding relays, which are located in several electrical circuits of the car;
If an attacker discovers where the immobilizer is located and dismantles it, he will not receive a positive result. The ECU will wait for a signal from a device that does not exist, since receiving the IMMO signal is written into its program;
thus, it is necessary to either rewrite the ECU program or install a pure electronic element (chip) responsible for this process. Attackers don’t have time to reprogram and re-solder.

Important: the standard IMMO will conflict with the alarm system if it has an auto-start function. A key or keyless IMMO crawler should be used. In this case, it is necessary to foresee in advance where the key crawler will be located.

Are further blockages possible?

After unlocking, the immobilizer can lock the car again in the following cases:

When the battery is disconnected.
10 seconds after the ignition is turned off.

After turning off the ignition, you will need to enter the code again. If you enter it incorrectly 3 times in a row, the next attempt will be possible after five minutes. Please note that all of these steps are not suitable for decoding a code solenoid valve or computer. Entering the emergency code will only allow you to start the engine.

other methods

If the immobilizer has blocked the engine of a Grant or other cars from starting, you can contact a service station, where they can either turn it off completely or install a lineman. The latter can apply voltage to certain terminals and thereby close the necessary contacts. Such a device deceives the ECU, and the engine starts successfully.

Professional technicians can interfere with the operation of the electronics by disconnecting the immobilizer itself from the car’s electronics. But if you do this yourself, you can harm the entire system.

Innate curiosity or an irresistible thirst for creativity

What is the point in replacing an electronic unit that performs important security functions? And the reason should be quite serious, since the consequences, after an unsuccessful attempt at independent intervention, will be extremely sad. Moreover, if there is no experience in such work and no idea where the IMMO itself is located and how to find it.

There are not many reasons why car owners want to dismantle the standard immobilizer or reconstruct it:

regular IMMO periodically does not execute commands from a chip key or personal tag;
he stopped accepting commands and immobilized the car;
a standard immobilizer prevents careless car mechanics from diagnosing the cause of failures of some car components;
opposition to mounted alarm system, with remote start, IMMO;
natural stinginess and desire to save, regardless of the consequences.

For all of the above reasons, there is one simple solution - contact a professional car service. It is his specialists who will reflash the ECU or replace it. In this case, a trained set of keys or tags will be handed to the driver with warranty obligations. For a simple motorist, who sometimes has little understanding of all the intricacies of an electrician’s work, it will not be at all easy to even find a standard IMMO.

The search will take a long time and with big problems. Devices assigned security functions are not displayed. The secrecy of the device is the first line of defense for the car. You can try to find the place where it is located - there is time and there are conditions for this. Another thing is car thieves. They have neither time nor conditions.

In such searches, you will have to take apart a lot and, having sorted it out, you will not find what you wanted to find.

In such searches, even the smallest landmarks are important:

1. For standard immobilizers with LED indication;

this place can be detected by the wires coming from the LED;

2. For standard IMMOs with chip keys and contact marks;

Not far from the steering wheel, along with the engine start switch, there is a special antenna that receives the signal from the key transponder. Its switching will indicate the location where the immobilizer is located;

3. For standard immobilizers with a transponder, contactless tag or card;

Finding the place where the desired device is located is not just difficult, but physically impossible. We'll have to go through half the car.

Important: there can be only one justification for independently replacing IMMO - the absence, in the vast expanses of the Motherland, of accessible auto centers with the necessary specialists.

Troubleshooting

Many immobilizer problems can be fixed by simply replacing the battery in the key fob. Transponder keys rely on a small battery to transmit a security code to the car's immobilizer. Be careful when replacing the battery to avoid accidentally damaging the transponder chip.

If you replace the battery and the key fob still does not work, there may be some damage to the transponder chip. In this case, you will have to contact your local dealer and request a new key. Such a replacement is not cheap, so be prepared to pay a hundred or even several hundred dollars for a new key. Typically, the more expensive the car, the more it will cost to replace the key fob.

Immobilizer system problems may be due to corrosion or damaged wires. The engine control unit or its sensors may be broken or faulty. In such situations, for further troubleshooting, you will need to contact a car dealership or car service specializing in electronics.

Where is it located during standard installation?

The problem of finding places where a standard immobilizer may be located can be solved by the fact that the device is “standard”. On the assembly lines of car factories, they did not bother to solve the problem of changing the location of the IMMO for each car. In-line production is just that: in-line and monotonous. Any change is a disruption to the operation of the conveyor.

It is enough to know the place where the standard immobilizer is located on one car, and it will immediately become clear where it is located on other cars of this model:

1. Where is the immobilizer located on the LADA Priora car;

immobilizer APS6 (small box, 100 mm in size - located behind the side covers of the center console. In its lower part.

2. Where is the immobilizer located on LADA Kalina;

The APS6 immobilizer is located behind the dashboard, radio and heating controls;

3. Where is the IMMO on LADA Granta;

The immobilizer is located behind the vehicle's dashboard. Exactly where the wiring from the ignition switch antenna leads;

Poor contact with antenna

In this case, problems will arise with starting the engine. Sometimes the engine will start not on the first try, but on the third, fifth or even tenth. The cause of failure usually lies in vibrations during movement.

Contacts may wear out and plugs may become loose. No one is immune from contact oxidation or dirt getting onto the connector.

If you notice problems with signal reception and transmission, disconnect the receiver from the antenna adapter, turn off the power supply, and treat the contacts with a special anti-oxidation agent. If they are loose, tighten the antenna elements. Now there should be no problems starting the engine.

If the immobilizer often produces glitches, think about it: maybe it doesn’t make sense to constantly repair it, but it’s better to buy a new device, install it on the car and not suffer trying unsuccessfully to start the engine.

How to find out the immobilizer code by VIN code

Every modern immobilizer is a device that protects the car by blocking the engine. Such a device has its own individual code, which allows you to disable the security system in emergency mode. Some drivers manage to lose immobilizer codes, but don’t know how to restore them. A lot of information about each vehicle is encrypted in its VIN code, including information about the immobilizer code. Knowing the VIN code of his vehicle, the driver will be able to restore the immobilizer code without any problems. More details on how to do this will be discussed right now.

Types of faults

Malfunctions in the operation of the car immobilizer unit can be divided into two classes - software and hardware. In the first case, the problem may be the destruction of the software recorded in the engine system control module. The standard immobilizer can fail as a result of desynchronization between the unit and the key.

Hardware errors and failures usually include a breakdown of the microcircuit or system control key. If the circuit is intact, then the reason may be a break in the communication buses, which are responsible for the exchange of information between the elements of the blocker. Regardless of the class of failure, detailed diagnostics and repair of the device or key will be required.

What is an immobilizer and why does it need a code?

An immobilizer is a small device that allows you to protect your car from theft by completely blocking the engine. The characteristic features of immobilizers can be considered:

the ability to connect to the car using wires or without them at all;
unlocking the system using radio tags, voice input or entering a code combination on standard buttons;
devices are very compact in size;
security systems with or without additional functions;
There are no buttons on the main blocks; they can be hidden anywhere;
have access to hood locks and can connect to standard alarms.

Each immobilizer has an individual code. It can contain from 4 to 7 characters. It is indicated on a special plastic card, which is easy for the car owner to lose. It is almost impossible to recover a lost code using the selection method, but using VIN code data is quite possible, and very quickly.

Purpose and principle of operation of the immobilizer

Translated into Russian, the word “immobillizer” means “immobilizer.” The device is an electronic circuit included in the car's wiring, which eliminates the possibility of unauthorized starting of the engine for the purpose of stealing the car. This is achieved by interrupting the vital electrical circuits of the machine. This module, unlike alarm systems using public address systems, operates covertly.

The main task of the device is to prevent the theft of a vehicle even if the interior is opened by attackers. In order to increase the efficiency of its operation, relays are installed in the circuit that block engine starting when the immobilizer is disconnected or removed, and even when the wires are shorted in the “correct” combination. Some models are combined with a standard alarm, which, when triggered, triggers the blocking.

The immobilizer includes the following elements:

The electronic unit, or the “brain” of the device, in which key codes are located and processed.
Engine control unit (ECU).
Reading coil.
Electromagnetic relays that break circuits and immobilize the machine.
A key held by the driver that acts as a control element and activates the system.

The immobilizer can block either a single unit (power unit, gearbox, brakes or steering) or several units.

What is a VIN code and what information does it contain?

Every person goes to stores, buys different goods, and on each of them they can notice a mark such as a barcode. This code contains complete information about a specific product and its manufacturer. For a vehicle, a unique barcode is the VIN code. It is there that hides complete information about the car for the entire time that has passed from its release to the last moment of operation.

This 17-digit code, consisting of numbers and letters of the Latin alphabet, allows the motorist to find out the following information:

date of manufacture of the car and its features;
information about the vehicle manufacturer and the features of a specific model;
data about the events that happened to the car during its entire operation - mileage, fines and accidents, whether it was mortgaged, whether the car was the subject of theft, how many owners have changed;
necessary data to restore lost codes of various security systems;
other information that concerns the vehicle and all its owners.

Deciphering VIN codes on your own is not a reality, because to calculate the necessary data you need to use a special calculator. Users will be able to download this program for decoding codes onto their personal computers or mobile devices or decipher the VIN code online.

What is a Thatcham device?

Thatcham Research is a not-for-profit group working with manufacturers, trade bodies and legislation to promote vehicle safety standards.

In the 90s, Thatcham grouped immobilizers and car safety devices into different categories, which the automotive industry now uses as benchmarks - there are eight in total.

Safety devices not approved by Thatcham are not included in these eight groups and are referred to as class 'Q' devices.

What determines which code is used for a particular immobilizer?

Regardless of how expanded the functional range of immobilizers of different brands and models is, their main function is to protect the vehicle by blocking the engine. Each immobilizer has its own unique code that will help unlock the system in case of emergency. Its value can contain 4, 5 or 7 characters. How long the immobilizer code will be depends on the following indicators:

car make, model and production time;
immobilizer brand;
immobilizer release time;
the specific model of the blocking device and its power.

The size and meaning of the code depend on several indicators. Having studied them, you can determine exactly how many characters are hidden in the immobilizer code, but choosing the right combination is pointless, especially if you need to unlock the system urgently.

Disabling or bypassing the immobilizer

The process of disabling the blocker depends on the make and model of the car, but in general the following methods are used:

Deactivate immo using a password. If there is a special code, the values are entered on the car’s dashboard, as a result of which the device recognizes and turns off.
Disabling using a spare key. The immo antenna is connected to the chip from the spare key. Before this, the chip itself must be carefully removed from the key and taped to the antenna with electrical tape.
Deactivating the device using a computer and special software.

You can make and install a device that will bypass the operation of the blocker so that the latter does not interfere with the operation of the car.

Items that will be required to manufacture the bypass module:

chip installed in the spare key;
a piece of wire;
Scotch tape and electrical tape;
relay.

The procedure for making a lineman is as follows:

A 15 cm piece is cut from a roll of electrical tape.
The electrical tape is then wrapped around the tape.
At the next stage, a piece of wire or wire needs to be wound onto the resulting skein. Approximately about ten turns should come out.
Then the electrical tape is cut slightly with a knife and wrapped on top.
The electrical tape is removed and its excess parts are trimmed.
The wiring is soldered to a piece of wire. The adhesion site must be isolated.

Where and how can I download the code calculator

Every vehicle owner can use the car code calculator without any problems. Such calculators work on a very simple principle, the essence of which lies in the following steps:

logging into the code calculator system;
search for a special field intended for entering data;
prescribing codes with the search term and indicating other personal data;
sending VIN or other code for decryption;
waiting for a response from the system and receiving the result.

In the calculator, you simply need to enter the VIN code in full and provide additional information about yourself. The system, after processing the entered data, will be able to send the user a full report on the work done, and send all the data that the user was interested in to his email account.

This calculator can be downloaded to most electronic and multimedia devices without any problems. To install a calculator for calculating the immobilizer code by VIN code, proceed as follows:

go to one of the search engines on the World Wide Web;
enter in a special line the request “download calculator for calculating the immobilizer code by VIN code”;
review several search engine results and find a licensed version of the program;
check the program file before downloading for viruses - for this, an antivirus must be installed on the device;
download the file in which the calculator is sealed and install it on a multimedia device;
open the program and enter all the data necessary for the calculation.

You won't have to wait long for the results. In addition to the lost immobilizer code, the user will have the opportunity to use the VIN code to find out a lot of useful information that relates to the features of his vehicle. Using the calculator will be absolutely free. Most often, a car is sold with a standard immobilizer installed in it and its code, like other data, is encrypted in the VIN code set.

Linemen

As usual, immobilizer scanners are installed at service stations. They can also completely disable the protection system, but this must be done by good specialists, since here they will have to interfere with the operation of the electronics.

Do I need to be connected to the Internet to use the code calculator?

To download a program that can read and decipher different codes and meanings, you must first find it on the Internet. After downloading, the code calculator will become a regular program that will always be present on the working panel of your mobile device or PC. But is downloading the program enough to restore the immobilizer code using the VIN code? This is not enough and the reasons for this response were the following features of the system:

all data about cars is stored in an online database and in order to receive it, the program must have an Internet connection;
if the user would like to download such a data table, the process will not be possible, because it takes up too much memory and must be constantly updated, but this is impossible in offline mode;
Only an Internet connection will allow the system to calculate current data on the VIN number, and not read outdated information.

Immobilizer Check

Before you start searching for the cause of the immobilizer failure, you should check and correct, if necessary, the following parts of the car:

Battery, and in case of insufficient charge, recharge.
Use the original ignition key specific to the vehicle model being used.
Remove other electronic and gadget devices that can interfere with the immobilizer signal.

You can check the functionality of the device by wrapping the key in food foil and inserting the lock into its ignition. If the key indicator on the dashboard does not light up due to signal shielding, the car will not start. When the foil is removed, the engine should start.

VIN code and immobilizer code are the first things a person should know when buying a car.

If a person went to a dealership and decided to buy a new car, then the presence of an immobilizer on it is a common thing, and VIN-CON is present on absolutely all cars. When purchasing, the driver must find out the meanings of these two encodings, because the vehicle will become his property and knowledge of its features will help to avoid problems in the future.

When buying a car that has already been used, it is worth finding out these two codes or at least the VIN code for the following reasons:

the VIN code will help to read complete information about the vehicle and the previous owner will not be able to hide any unpleasant facts from the buyer;
The immobilizer code will allow you to effectively use the security system and, if necessary, change its settings;
The immobilizer code will help you find out how effective this device really is;
The VIN code will help you check any car for theft and, if you lose the immobilizer code, calculate it.

Determining the immobilizer code by VIN is an easy process, but you also need to know the VIN. Using the VIN code, the calculator reads all data about the car and allows you to restore the operation of systems to which access was completely or partially lost. The immobilizer code is a security element of the security system. After all, in order to hack it you will have to enter exactly this value. Attackers will not spend half a day trying to figure out codes to steal a car and will simply leave it alone.

A VIN code is a 17-digit set of numbers and letters that allows you to find out information about a specific car, including the immobilizer code. If the code card is lost or a similar problematic situation occurs, do not despair, because a special calculator and VIN code will allow you to calculate the required combination in a short time. It's fast, simple, and most importantly, absolutely free and available to every car owner.

Transponder immobilizer system: what are the features and differences?

On modern cars you will most likely encounter just such a system. Its advantage is that it minimizes the risk of possible theft.

What makes it special? To activate the transponder immobilizer, even a professional auto mechanic will have to spend a lot of time and go through almost the entire car.

And the essence of such a system is contactless response.

The transponder immobilizer is locked or unlocked thanks to a special key fob or card, in which a special code or cipher is encrypted.

When the key is within the range of the immobilizer receiver, the car is unlocked and the owner can safely start the engine and drive in any direction.

When he moves away from the car, it will no longer be possible to start it in any other way, since the immobilizer is simply blocked.

Such a transceiver can also be hidden anywhere. The instrument panel, engine compartment, and seat upholstery are suitable for this. The most important thing is to make the disguise as reliable as possible. It is also impossible to find it using special equipment.

Self-installation of immobilizers is practically not carried out, since this requires high professionalism and extensive practice in working with such a device. Therefore, if you want to install an immobilizer on your car, it is better to contact specialists about this.

How can I find out if my car has an immobilizer?

Fanatus Vulgaris

You don’t need to show it to anyone, it’s very easy to check. wrap the part of the key that you hold with your fingers in foil from under the chip and try to start the car, since the chip is in the handle of the key, the foil will screen the signal from the chip in the key and the immobilizer will not receive a signal to unlock, as a result the car will start, but after a couple of seconds will stall. that's how you'll find out.

Without getting up from your computer, you can determine the vehicle's equipment at the manufacturer. Right here !

For free. According to the vehicle VIN, it is true that registration is required, but it will not hurt when ordering spare parts and searching for part numbers.

But. 1. If something has been tampered with in a car with an immobilizer, the manufacturer does not know it, and neither does this site.

2. There really should be a red round light bulb - but it can burn and go out, following the will of Belarusian or Lithuanian auto electricians.

3. The key manufacturer can only determine whether there is a chip in the key, but he cannot know whether there is a working immobilizer in the car.

4. The most reliable option is maux10n

- foil. But it’s a little weird for me to advise this. Suddenly something wrong gets blocked, the auto brain is no joke. And roads.

How can you find out if there is a standard alarm without a trip to the dealer? We don’t have a dealer in our city, but the question is bothering me. In the package I found: LMGP: Automatic Headlamps LNJP: Fog Lamps LSAP: Security Alarm

MLEP: Front Body Color/Chrome Fascia MLVP: Rear Body Color/Chrome Fascia

What does this mean? standing, but not active?

LSAP: Security Alarm

. . . What does this mean? standing, but not active?

In my opinion, this is not really about signaling, i.e. about the alarm system, but not about the anti-theft one. Correct me if I'm wrong with my knowledge of English.

About the immobilizer

it should be written, for example:
GXXS Sentry Key Theft Deterrent System
And about the alarm - I can’t find what it should be, but, Security Alarm - IMHO - Emergency alarm.

How does an immobilizer differ from a regular alarm system?

The main difference between an immobilizer and an alarm system is its shorter range of action and a more advanced, one might say, intelligent principle of protection. All this significantly reduces the likelihood of car theft.

For example, in order to intercept a signal coming from the key fob of a conventional security system, an attacker can be located at a considerable distance from the car - several tens of meters.

This will not work with an immobilizer; to intercept the signal you need to be directly next to the car, and this limits the possibilities of car thieves significantly.

Another advantage of the immobilizer is the almost impossibility of copying it, because for this you will need a special master card, which cannot be said about alarm key fobs, which in our time, by knowledgeable people, can simply be duplicated.

What to do if the immobilizer has blocked the engine from starting

Unlocking the immobilizer can be done in several ways, much depends on the type of device installed in a particular brand of car.

Common methods:

Using an infrared transmitter;
Using the central locking button.

Unlock using IR transmitter

The method, if the immobilizer has blocked the engine, is suitable for types of devices in which the central locking and immobilizer are controlled by an IR key, for example, like in Mercedes cars.

In this case, you will need a four-digit code, which is entered during the unlocking process by pressing the on-board computer button (hereinafter referred to as BC) while holding down the gas pedal. The button is located on the windshield wiper switch at the end (not on all cars).

Algorithm of actions:

Activate the immobilizer and turn on the ignition;
A flashing light on the instrument panel will indicate that engine starting is blocked;
We remove the blinking of the lamp by squeezing the gas pedal;
Find the BC button. Without releasing the gas pedal, press it as many times as the first digit of the code;
Take your foot off the pedal and the lamp will start flashing again;
We press the pedal again - by pressing the BC button we enter the second digit of the code.
Let's release the pedal;
We repeat the same steps two more times.

A constant light on the lamp, regardless of whether the gas pedal is depressed or not, will indicate that the immobilizer is unlocked and you can try to start the engine.

If the code was entered incorrectly, the immobilizer will block the engine again. Nothing bad happened, you have two more tries. If they were not successful, then after 15 minutes you can repeat them.

How to unlock using the central locking button

To unlock the immobilizer using the central locking control button, you will need to enter an emergency code.

It is important to understand that using the steps listed below you can only start the car, but not decode the computer and the solenoid valve.

Algorithm of actions:

Turn on the ignition. The light on the instrument panel will flash slowly.
Turn the ignition off and on again. The light will flash faster, other lights will appear and go out after 3 seconds.
After pressing and holding the central button on the key fob, the lamp will flash more slowly.
Carefully monitor the blinking process, it is important to count the flashes and when their number is equal to the first digit of the code, release the central button on the key fob.
Press and hold the button again. We release it as soon as the number of blinks matches the second digit of the code.
We repeat this two more times.

That's it, the immobilizer is unlocked and you can start the engine. But when the ignition is on, a lamp flashing every 3 seconds will indicate that the protection is disabled.

The immobilizer will be locked again, after which you will have to enter the code again if:

You turn off the ignition for more than 10 seconds.
Disconnect the battery.
The device will be blocked for 5 minutes if the code is entered 3 times in a row with an error.
