How to make a spare key for a car

On the updated Lada Granta FL family, as well as on the Lada Granta Cross, in some trim levels a folding ignition key has appeared, which also acts as a remote control for the central locking of the car. This innovation is not available to everyone; Lada Granta FL cars will be equipped with a folding key in the Luxury trim level, and on Lada Granta Cross cars the folding key is available in the Comfort and Luxury trim levels.

Types of keys

These devices have been in use for quite some time and have undergone several modifications. Therefore, on different car models of different years of manufacture you can find the following chip key options:

Separate. This type was used on VAZ models and can still be found now. Here, to start the engine, two things are required - the ignition key itself and a special remote control - a communicator. To start the car, you first need to bring the communicator to a special reading device, then the engine lock will be disabled. After that, you can start it with the key. But there is a drawback - you always need to have both of these things with you, and one of them can easily be lost, and then you won’t be able to start the car.
Chip in the key. This is the most common option now. Here the chip is located inside and is powered by a miniature battery or battery. You cannot start the engine without such a key, and usually there are several in the kit.
Map. To launch some foreign models, a special plastic card is used - a flat device in which a microcircuit is built-in. This card is inserted into a special reader on the car console, and the engine is started using the “Start” button.
Wireless. Such a device does not need to be inserted anywhere or even taken out of your pocket. It communicates wirelessly with the car blocker, and they only need to be nearby. If there is no such device, then the engine will not be able to start. If the owner moves too far, the system completely blocks the engine and doors. When you get close, everything will unlock.

The second option is the most common and such a key can be recovered, so we will talk about it further.

Disassembling and replacing the folding key battery

The remote control uses a consumable battery (battery), so sooner or later you will have to disassemble the key and replace it. To disassemble the folding key and subsequently replace the battery, you will need the following:

New battery (CR2025 or CR2032)
Flathead screwdriver (or any other flathead tool)
Small piece of fabric

The folding key must be disassembled with the key blade exposed, as shown in the photo above. There is a recess at the end of the key into which you need to insert a flat-head screwdriver (it would be a good idea to wrap the screwdriver blade with a cloth so as not to damage the plastic body of the key):

Then you need to turn the screwdriver clockwise, if your result is similar to what is shown in the photo below, then you did everything right:

and now you can proceed to directly replacing the battery. If nothing works for you, most likely the area of your screwdriver is too small, as a result of which the necessary force is not created on the housing cover, try to find a more suitable tool.

The power supply element of the remote control is shown in the photo above, remove it and replace it with a new one. Most often, Lada Granta FL folding keys use a coin cell battery marked CR2025

However, sometimes there are remote controls with a
CR2032
. These two power elements differ in thickness (the difference is several millimeters); any of them will suit the remote control.

Why do you need a duplicate?

Having only one key, a car owner can face big troubles in a variety of situations:

the key may be lost or stolen;
the transponder can be forgotten somewhere;
you can accidentally leave it in the cabin and slam the door.

Of course, these are only the most common situations, but they are all very unpleasant, and you won’t be able to get inside the car, let alone drive. If the transponder is inside, it can be done by breaking the locks or breaking the glass, but if it is lost, you will have to make a duplicate, and a complete analogue of not only the key, but also the chip.

Where to make a chip key for a car

Just a few years ago, to get a duplicate you had to contact an official dealer and place an order. Then we had to wait a long time for it to be manufactured and delivered at the factory. It costs a lot and takes a long time, and all this time the car is forced to stand idle.

Now you can make a duplicate in the city at a service station, and quite quickly. Where car keys are made, you can usually order a copy of the chip key. It is very difficult to do this on your own, as special equipment is required. And if the metal part of the key can still be made after several attempts, then it will be difficult to program the chip correctly. After all, you also need to read the information from the original or from the dashboard.

Of course, everything is simplified if you have the original key and you just need to make another copy. But it is much more difficult if it was lost. Accordingly, the cost may vary.

How much does the service cost?

There are many specialized workshops where they make new car keys. Prices are different everywhere, depending on both the city and the car model. For example, for Moscow the cost of work is approximately the following:

restoration of keys in case of complete loss – from 5,000 rubles;
cutting a new blade (if, for example, it breaks) - 700 - 1200 rubles;
production of a key for the ignition switch - from 3,000 rubles;
chip programming – from 2000 rubles.

Prices may be slightly different in other regions. If you bring the original to a specialized workshop that has all the equipment, cloning it will take literally 15 minutes. If there is no original, then you need to deliver the car there or call a specialist to extract the necessary information.

How to make a duplicate key with an immobilizer yourself

You won't be able to make a second set of keys for your car yourself. To do this you need to do the following operations:

make a copy of the key itself, its blade, and very accurately. The blank can be bought, for example, on Aliexpress;
purchase a special capsule with an empty chip, which is installed in the key. It is more difficult to find, but possible;
read information from the original;
flash a new chip;
install the capsule into the key.

All these operations require high precision and special equipment, which can only be available to those who do this professionally. Even making a key blade requires a professional approach - the slightest deviation will devalue the entire work. Therefore, specialized workshops use special machines that reproduce the original with perfect accuracy. Of course, you can also work with a file, but that's only half the battle.

Contact car immobilizer

Programming the chip also requires special equipment. Incorrect determination of the original PIN code also nullifies all the work. If the original is not there, you need to restore the key to the ignition switch and read information from the on-board computer, then this becomes a completely impossible task for the average car owner.

AvtoVAZ key training procedure (Video)

And once again about learning ignition keys on cars produced by AVTOVAZ. Not everyone apparently understands the technology for reading the key code and, accordingly, the learning procedure causes difficulties.

The key code is read remotely! And in fact, there is no need to even insert the key into the ignition switch, because you can turn on the ignition with a simple jumper (connect the pink wire on the ignition switch block and the blue-black one) and the ignition is on.

The main thing is the presence of both a training chip (in a key with a red plug) and then a working chip or control panel in the reader area (communication coil). Correct operation is ensured when the chips are located at a distance of up to 3 cm from the coil and approximately in the center.

The coil is located under a plastic cover that covers the lock cylinder. The easiest way to carry out the procedure is to still have a sting from your key, even without a chip. The main purpose of the sting is to turn the ignition on and off during the procedure.

At the end of the article there is a video on how to train or retrain keys in a way that may be necessary if you need to train an additional chip or if an anti-theft lock with a different key is installed...

All steps in the learning process are announced by the beepper of the body electronics unit.

Insert the learning key or bring the learning chip in, turn on the ignition, wait 2-3 seconds, turn off the ignition.

The immobilizer light blinked - the procedure opened. The lamp will blink during the entire procedure. And if it suddenly goes out, it means something went wrong or you made a mistake somewhere. Start over...

Removed the training key or chip to the side.

We inserted a working key or brought a working chip, turned on the ignition - we wait...

Three beeps, pause, two beeps, turn off the ignition.

Removed the working key (if you need to train another working chip or key, repeat the previous step with the second chip or key...

They inserted the learning key again or brought up the learning chip (this is the last step - closing the procedure) and turned on the ignition...

Three beeps, a pause, two beeps, the ignition is turned off, but we do not remove the training chip from the communication coil. We watch the lamp. After the warning lamp doubles its flashing frequency (on previous generation cars) or the buzzer sounds (Priora 2, Kalina 2, Granta Lux), turn on the ignition again and wait 3 seconds. That's it - training is complete!

Manufacturing instructions

The car owner himself can take some steps if the original key has been lost:

You need to remove the ignition switch from the car in order to make a new key using it. But manufacturers have specifically complicated this task for security against hijackers. Therefore, you may have to turn to the experts. Then you need to remove the secret part from the lock, and this is also difficult to do without help.
The secret part should be taken to a place where they make keys, preferably car keys. There, based on the location and design of the teeth, they will be able to cut a new blade, the same as an old car key.

Then comes the stage of working with the chip.

Instructions for activating the standard immobilizer

Close the doors.
Turn on the ignition with the RED key and wait at least 6 seconds.
Pull out the key. The machine should blink at a frequency of 5 times per second.
Quickly (within 5-6 seconds) turn on the ignition BLACK.
3 squeaks + 2 squeaks.
Turn off the ignition and remove the key.
Quickly (within 5-6 seconds) while the car is blinking, turn on the RED ignition
3 squeaks + 2 squeaks.
Turn off the ignition RED KEY IN THE LOCK.
1 squeak.
Quickly (within 5-6 seconds) turn on the ignition for 2-3 SECONDS!
Turn off the ignition. KEY IN THE LOCK
3 beeps + machine goes out. We do not remove the key. (When working with some controllers, the light stops blinking and the buzzer emits 3 sound signals when you turn on the ignition. In this case, you should still turn off the ignition and wait at least 10 seconds)
wait at least 10 seconds.
Remove the key.
Checking immo activation. We turn on the ignition with any key, if when you turn on the ignition the car on the dashboard does not light up, then the immo is activated.

The learning process is also shown in the video:

Crib:

Close the doors.
Red - ignition for 6 seconds - remove
Black - ignition 3 beeps + 2 beeps - remove
Red - 3 beeps + 2 beeps - ignition off - 1 beep
Ignition on 2-3 sec - ignition off
Do not turn on the ignition for another 10 seconds.

To resynchronize the codes, turn on the ignition of the vehicle. Wait 6 seconds. If the CL starts flashing once per second (error), turn off the ignition and wait at least 10 seconds. Then turn the ignition back on. The CL should not blink, but the engine should start.

If 3 seconds after turning on the ignition the key light remains on continuously, it means that the anti-theft function is not activated and the key learning procedure should be repeated again.

Programming Features

It is impossible to give any specific advice on programming transponders. Each car model has differences in both software and safety systems, not to mention the design. Therefore, the keys can differ greatly even between different models of the same manufacturer, and even more so between different ones.

In the most general case, programming a new chip occurs after reading information from the original or from the dashboard. This requires special programs and equipment. Therefore, this is done by specialists who have experience working with different car models.

Therefore, it would seem that such a simple operation - making a second key for the car - today requires turning to specialists. You can't do this on your own.

Making a chip for autostart

To manufacture an autostart chip, special equipment is also required. In the simplest case, the information is simply transferred to a new “blank” - an empty chip. In difficult cases, each new device requires entering its codes into the on-board computer. So this also requires turning to specialists.

The best prices and conditions for the purchase of new cars

The average car owner has several items that, if lost, cause great stress. Few people experienced pleasant sensations when they did not find a driver’s license or registration certificate for a car in their pocket. A little less, but still a nuisance, is the loss of an insurance policy (CASCO or OSAGO). But according to statistics, drivers lose their car keys the most. And it’s good if this embarrassment occurred close to home - then there is a chance to use the second key, which, as a rule, comes with the purchase of a car. But if the car keys disappeared from the car owner’s pocket away from home, then it’s more complicated. And yet there is a way out of this unpleasant situation.

As soon as you discover that the car key is missing, immediately contact your family and friends and find out if it is at home. If the search for home ones is not successful, it is necessary, as mentioned above, to ask them to bring you a second set of keys, which are handed over by the car dealer upon completion of the car purchase/sale transaction. If you purchased the car second-hand and you do not have a duplicate key, or it was also lost, you will have to use outside help.

Let's say your car is new. Then you can call the dealer from whom you purchased the car and ask them to pick up a duplicate key for you. To do this, you will have to provide the dealership representative with information about the car (license number, model, year of purchase), including its VIN code. It’s good if you have this information at hand, but if the VIN code is indicated on a plate located in the engine compartment or on the front door opening, the situation becomes more complicated. In this case, you will have to call a tow truck, which will deliver the car to the salon, where its employees will open the doors with a duplicate key and hand it to you. Naturally, the car owner will have to pay for all these operations out of his own pocket (although for those drivers whose car is still under warranty and is covered by free assistance services, they can call a tow truck and open the doors for free). This method is suitable for those whose car was purchased from an official dealer. If the “iron horse” was purchased on the secondary market and there is no duplicate set of keys, then you will have to act differently.

Now in Russia there are many companies that provide services for making duplicate car keys based on the lock cylinder. Since the key for all cars is suitable for both opening the doors and the ignition switch, this restoration method is quite simple and, compared to restoration through an official dealer, inexpensive. However, there are also unpleasant exceptions to this method. The fact is that in many Japanese cars the design of the door lock cylinder is such that it will not be possible to make a duplicate key using the first method. There is still a way out: this is a purchase at any disassembly of the kit - an ignition lock, a door lock cylinder and two keys. Having purchased such a kit for your car (when purchasing, you need to check whether these parts will fit your car), you can call a specialist who will replace the ignition switch and door lock cylinder (if the key opens the passenger door and trunk).

All the recommendations described above apply to keys that are not equipped with a microchip associated with the immobilizer installed in the car. Today, almost all car models are equipped with factory immobilizers. In this case, making a duplicate key without a chip that unlocks the immobilizer is pointless - you may still be able to open the car door, but not start the engine. In this case, there is only one way out: contact an official dealer for help. Having called the dealership and reported the problem, you need to be prepared for the fact that the car will have to be transported by tow truck to the car dealership - usually such a home-visit service is not provided. You will make things much easier if you find the card that dealers give to the buyer after purchasing the car. It contains a radio code and an immobilizer code. If you haven’t found such a card, you’ll have to put up with the expenses that will be spent on restoring data about the immobilizer code. The timing here is also different: there have been cases when the dealer received the code and made a duplicate within several weeks, or even a whole month. When the key with the immobilizer chip is in your hands, do not rush to use it: the auto center specialists will have to reset all the data on your car’s immobilizer and configure new parameters so that the key not only opens the doors, but can also start the engine. This, by the way, is a guarantee that the person who finds your key will not be able to open the car doors and start the engine.

Those who own a car purchased second-hand should not despair - their key with a chip can be restored without contacting official dealers of the brand. Today there are companies that have programs that can select codes for almost any immobilizer. They also produce chip keys, and this operation, as a rule, costs less and is carried out faster than from an official dealer. The only question is whether you will entrust such confidential information to such a company - after all, the production of chip keys from official representatives of automobile brands is more reliable.

The immobilizer is designed to prevent unauthorized engine starting.

The immobilizer for cars of the LADA GRANTA and LADA KALINA 2 families consists of an immobilizer control unit integrated into the instrument cluster, a communication coil structurally located in the ignition switch, a training key 3 (Fig. 1) with a red container 4, a working key 2 with a remote control door locking, warning light 1 located in the instrument cluster and the corresponding part of the ECM software.

Rice. 1. Immobilizer composition
:

— immobilizer warning light in the instrument cluster;

— working ignition key with remote control (RC);

— training ignition key;

— a red container with a transponder (encoding device).

The operating modes and states of the immobilizer are displayed using a warning light and a buzzer inside the instrument cluster.

The instrument cluster communicates with the ECM via the CAN bus.

The ECM and instrument cluster can be in one of two states:

— with the immobilization function turned off (“clean”). In this condition, the ECM and instrument cluster are not a single system, and engine starting is permitted regardless of the instrument cluster;

— with the immobilization function turned on (“trained”). In this condition, the engine can only operate if the ECM receives the correct password from the instrument cluster.

The ECM and instrument cluster enter the trained state after completing the immobilizer training procedure, which is performed using a training key. After its execution, both blocks go into a trained state, and it is impossible to return them to a clean state.

When the learning procedure is completed, the system generates a new password, which is stored in the non-volatile memory of the ECM and instrument cluster. This new password is also written into the training key. After completing the training procedure, the training key with which it was performed becomes “its own” for the data of the instrument cluster and controller. In the future, the training procedure must be carried out only with “your” training key.

ATTENTION. The training key cannot be used to train any other instrument cluster-ECM pair.

During the procedure for transferring the immobilizer to the trained state, the working key is also trained. This key is used to disarm the immobilizer when operating the vehicle.

After completing the learning procedure, the door lock remote control is also activated.

IMMOBILIZER TRAINING PROCEDURE (How to train the immobilizer on Grant and Kalina 2)

1 Close all doors.
Insert the learning key (the key with the red container) into the ignition switch. Turn on the ignition, after 6 seconds the indicator in the instrument cluster will light up with a constant light, indicating the untrained state of the immobilizer. ATTENTION.

During subsequent training of the immobilizer, the warning light will not light up when the ignition is turned on.

2 Turn off the ignition. The indicator should flash 5 times per second. Remove the training key from the ignition switch.

3 Within no more than 6 seconds after turning off the ignition, insert the working key and turn on the ignition. The buzzer in the instrument cluster should emit three beeps.

If the buzzer does not sound and the indicator stops blinking, this means:

— the time interval of 6 s has been exceeded and it is necessary to repeat the learning procedure, starting from step 1;

— the working key has already been trained with another immobilizer;

- the working key is faulty.

4 After the buzzer gives three beeps, wait 6 seconds until the buzzer gives two more beeps, turn off the ignition and remove the working key.

5 After turning off the ignition for no more than 6 seconds, while the warning light is flashing, insert the learning key and turn on the ignition. The buzzer should beep three times. Wait 6 seconds for the buzzer to emit two more beeps.

6 Turn off the ignition, do not remove the training key. The buzzer should emit a single beep and the indicator should flash twice as fast.

The time between the moment the ignition is turned off and the indicator switching to an accelerated flashing mode depends on the type of ECM controller, but should not exceed 15 s.

If the sound signal does not sound and the flashing indicator stops, you should return to step 1 and repeat the learning procedure.

7 After the buzzer gives a single sound signal, no later than 10 s, turn on the ignition. The direction indicators should flash three times and the buzzer will beep three times. After three beeps are heard, turn off the ignition.

ATTENTION.

When performing step 7, after turning on the ignition, the process of memorizing the codes by the ECM and instrument cluster begins, therefore it is strictly forbidden to turn off the ignition until three beeps from the buzzer have sounded. To guarantee completion of the code memorization process, the time between turning the ignition on and off must be at least 5 seconds.

Failure to comply with the above conditions may result in the ECM becoming locked.

8 Remove the learning key. Wait with the ignition off for at least 5 seconds.

9 Check the operation of the door lock remote control. To do this, press the door lock button on the remote control - the locks should lock and the direction indicators should blink once. Then press the unlock button on the remote control - the driver's door lock should unlock and the direction indicators should blink twice. To unlock passenger doors, press the unlock button on the remote control again

10 Check the operation of the immobilizer. To do this, turn on the ignition with the working key; the immobilizer warning light should not flash or stay lit. Perform a test run of the engine. If the engine starts, the learning procedure is completed and the system is operational.

ATTENTION.

If for any reason the training procedure was interrupted after performing step 4, then it must be repeated and completed without changing the system components (ECM, instrument cluster, code keys). If one of the system components, after an incomplete training process on one car, is trained on another car with different components, then software failures in its operation are possible.

DIAGNOSIS OF IMMOBILIZER FAULTS

When the system is in good working order and activated, the immobilizer warning light does not light up and there are no buzzer signals.
If, when you turn on the ignition, the immobilizer warning light comes on with a constant light or starts flashing, and after about 10 seconds the immobilizer buzzer sounds and the same signal is repeated after another 10 seconds, this means that the immobilizer is either untrained or there is a malfunction in the immobilizer system.

The number of beeps and indicator signals indicates the type of malfunction.

1 buzzer sounds and the immobilizer warning light flashes - “Key cannot be read” fault.

Possible reasons:

a) Malfunctions of the transponder circuit - this group of malfunctions is characterized by the absence of a “signal about the key left in the ignition switch” when the ignition is turned off and the driver’s door is open:

— a malfunction in the ignition switch communication coil circuit.

Measure the resistance of the communication coil between the contacts of the 2nd terminal block from the ignition switch, which should be within 6 - 8 Ohms.

If the coil resistance is normal, check the continuity of the circuit between the 2-terminal block to the communication coil and contacts “16” and “18” of the instrument cluster;

— there is no transponder in the training key.

Check the presence of the transponder and its designation (must be PCF7936AS). If there is no transponder, take a “clean” training key and a “clean” ECM controller and retrain the immobilizer system;

— the transponder in the key is faulty (detected during pre-sale preparation).

In the training key - you need to take a “clean” training key and retrain the immobilizer system.

In a working key with a remote control (RC) - it is necessary to replace the remote control with a “clean” one and retrain the immobilizer system;

— malfunction of the input transponder circuit of the instrument cluster — it is necessary to replace the instrument cluster and retrain the immobilizer system.

b) “foreign” remote control - this malfunction is characterized by the presence of a “signal about the key left in the ignition switch” when the ignition is turned off and the driver’s door is open.

It is necessary to replace the remote control with a “clean” one and retrain the immobilizer system.

2 buzzer sounds and the immobilizer warning light flashes - “No communication with the ECM” malfunction.

Possible reasons:

a) CAN bus break - restore the circuit between contacts “7”, “8” of the instrument cluster and the corresponding contacts “X2/D2”, “X2/F1” of the ECM;

b) Malfunction of circuits in the instrument cluster or ECM via the CAN bus - to identify a faulty product, it is necessary to test replace them one by one. If after replacing the product the fault code does not recur, it must be replaced;

c) There is no power supply to the instrument cluster or ECM.

Check for voltage at the ECM contacts:

— contact “X2/F1” — power supply from terminal “15” of the ignition switch;

— contacts “X2/H1”, “X2/H2” — power supply from terminal “30” of the ignition switch after the main relay.

3 buzzer beeps sound, and the immobilizer warning light is constantly on or flashing - the fault “The code of the read key is not in the instrument cluster memory.”

a) If, after turning on the ignition, the immobilizer indicator lights up continuously for 20 seconds and 3 buzzer sounds sound, then the immobilizer system has not been trained; the system should be trained;

b) If, after turning on the ignition with the training key, the immobilizer indicator flashes and 3 buzzer signals sound, then the instrument cluster is “foreign” or the key is “foreign”:

— “Alien” instrument cluster.

If the instrument cluster turns out to be “foreign”, to restore functionality it is necessary to retrain the system with a “own” training key for the ECM;

— “Alien” training key.

If the training key turns out to be “foreign”, to restore functionality you need to take a “clean” training key and a “clean” ECM controller and retrain the immobilizer system.

The buzzer sounds 4 times and the immobilizer warning light flashes - fault “The ECM does not confirm permission to start the engine.”

This means that the ECM was previously trained with a different system; it is necessary to replace the controller with a “clean” one and retrain the immobilizer system.

If, after turning on the ignition, the immobilizer warning light is on for 20 seconds and the buzzer does not sound, then the immobilizer is trained with its keys, but the ECM is not trained.

The system needs to be retrained.

Replacing a faulty ECM

In the event of a controller malfunction, a “clean” (untrained) controller must be used for replacement. To restore the functionality of the immobilizer after replacement, it is necessary to perform the immobilizer training procedure using the existing training and working key.

Replacing a faulty instrument cluster

If the instrument cluster malfunctions, any functional instrument cluster of the appropriate type must be used for replacement. To restore the functionality of the immobilizer after replacement, it is necessary to perform the immobilizer training procedure using the “own” training key for the controller.
