Author: Victor
Sherkhan Logicar 3 is a new car alarm model, the installation of which requires minimal intervention in the on-board network, thanks to the presence of a built-in CAN module. This function is not implemented in Scher-Khan Logicar 2; otherwise, the characteristics and capabilities of the security systems are identical.

Protect yourself from robbery
When using the alarm models listed here, the owner will be able to increase the level of privacy used by the system. You can activate two-step disarming: pressing the “1” key leads to arming, while to disarm it you need to know the code. The PIN code is entered by pressing keys, typing two or four digits in succession. The option in question is also provided in the Scher Khan Logicar 3 systems produced in recent years. And the text below is taken from the instructions for the “Magikar” signaling device.
How to activate two-step protection
By default, the Scher Khan Magicar 3 system does not use two-step disarming. To use this option, activate it:
- Disarm the car, turn off the ignition, turn off the “Hands-free” mode (see above);
- Press buttons “1” and “4”, hold them for 2 seconds;
- A short signal from the “dimensions” and a siren will follow;
- Press the "4" button 6 times;
- Wait 4-5 seconds, 6 signals will follow;
- To use a 4-digit code during operation, press the “2” key, and if you need a two-digit code, press the “3” key;
- Two or three signals will follow.
The entire sequence above will need to be repeated. In the fourth step, you will press the key not 6, but 9 times. In the sixth step, press the “2” button, thereby activating the protection. It remains to change the code value, which by default is “1111”.
Table of programmable options, "Magikar"
The instruction manual supplied with the Magikar systems contains several links to a page where one control sequence is given. Performing the actions specified in it will allow you to change the code:
- Disarm the car, turn off the ignition;
- Press buttons “3” and “4”, hold them for 2 seconds;
- A single signal should follow;
- Press the key fob corresponding to the first digit;
- After you hear the confirmation beeps, repeat Step 4 for the remaining numbers.
Setting the secret code in Scher Khan Logicar 3 systems is performed in the same way: you need to open the door, turn on the ignition and go to “step 2” indicated in the list below. The top list is suitable for Logicar without changes, but option numbered “6” is replaced there by “option 8”:
Programmable Options Table, Logicar
This means that in step “4” you will press the button not 6, but 8 times.
Let's say option “6” or “8” is in the “factory” value, and two-step protection is activated. Then, in order to disarm the car during operation, the “2” key must be pressed twice.
Disarming without a key fob
Modern equipment is equipped with a Valet button, the presence of which will allow you to disable the security mode when the key fob is lost. For the Scher Khan Magicar 3 signaling, everything looks simpler: within 4 seconds, turn the ignition on and off three times, and the system activates the “Valet” mode. If you have a key fob, then press the “1-3” keys, which will disable the “Valet” mode and disarm the car.
Marks on the ignition switches
Cars protected by a Scher Khan Logicar 3 alarm system are no more difficult to disarm: turn on the ignition, press the Valet button, first for a long time, then briefly. But if you set a PIN code, the system will not allow you to disable the security until it receives the correct value. This is also true for the Magikar family of signals. The instructions for them say the following:
- If option "6" is set to "2" or "3", first perform the steps required to disarm without using a code;
- After the “dimensions” flash, turn the key to dial the value of the first digit;
- Repeat “step 2” to enter the second digit;
- If the code was four-digit, enter each digit by analogy with “step 2”.
As a result, the system will switch to “Valet” mode, in which you can drive the car, use the central locking, etc.
Whatever alarm you use, always set a secret code. It is enough to enable option “6”, set the required value, and the car will receive additional protection. For Scher Khan Logicar 3 systems, use option “8”. By the way, even a two-digit code has 16 options. No one will go through them.

Connecting autorun in Logicar
Here we discuss how best to connect the Scher khan logicar 2 alarm system. It is initially equipped with auto-start, but the required circuit is not included in the basic instructions. The data given below is in the service documentation for Sherkhan equipment. And by implementing any of the schemes, you can get the autostart option without the need to carry out repairs later. We also note that any Scher khan car alarm needs to be configured.
Regular ignition switch
During installation, a set of terminal blocks is connected to the Scher khan Logicar alarm unit. To make autostart work better, the cord from the CN5 terminal block, the shell of which is painted yellow and black, is connected to the tachometer. The Sherkhan company's instructions also provide another option - connecting to a generator.
In general, the Scher khan logicar signaling system controls lighting equipment through this terminal block.
There is a loop on the body of the Sher khan security system, which is cut if autostart is implemented in cars with automatic transmission. After completing the installation, the system is configured - the “tachometer/generator” control method is set by option F2-30. Setting up the Starline signaling would be completed here, but the Scher khan logicar firmware provides a whole set of parameters. Change all values after installation. If the Sherkhan alarm emulates pressing the brake, configure option F2-21. Nevertheless, in order to provide the system with a valid autostart, the Scher khan alarm connectors are connected as follows:
Main features, advantages and disadvantages
Description of the features and capabilities of the Sherkhan Logicar 3 anti-theft system:
- Protection of transmitted signals from scanning and interception. For this purpose, the developer Sherkhan has implemented dynamic pulse encryption technologies.
- Audible and visual confirmation of executed commands. If necessary, the user can turn off the warning signals of the key fob, as a result of which only the vibration signal will work. All data on the state of the anti-theft system is displayed on the communicator display in the form of indicators.
- The ability to start the vehicle engine automatically, without the presence of the user in the car. The power unit can start based on temperature readings, at time intervals, or based on an alarm clock.
- Monitoring voltage in the on-board network. If the operating value is less than 12 volts, the user will be warned about this by sending a message.
- Possibility of using all functions of the anti-theft system on vehicles equipped with a keyless entry system.
- CAN and K-Line buses are used to exchange data between signaling elements. This allows for faster information transfer and system response.
- Possibility of using Slave mode. The security complex will be controlled using a key from the car’s standard central locking system.
- Availability of vehicle protection mode when the engine is running.
- Possibility of using a personal password, with which the system will be turned on and off in emergency mode. The use of the code is relevant in case of loss or breakdown of the pager.
- Silent car security. When activated, the siren does not give alarm signals; only external lighting devices work.
- Possibility of controlling the central locking of the car from the ignition system. The device will lock when turned on and unlock when turned off.
- Automatic arming in case of accidental disabling of the protection mode.
Advantages of alarms according to user reviews:
- Long range of two-way communication. The range of the pager declared by the manufacturer is up to 500 meters in command transmission mode and up to 1500 m when receiving messages.
- Extensive functionality of the anti-theft complex.
- Availability of protection against automatic engine starting when the gear is engaged, if the car is equipped with a manual transmission.
- Screen backlighting, making it easier to use and set the alarm in the dark.
Cons of Sherkhan Logicar 3 and 2:
- possibility of false positives;
- insufficiently detailed instructions;
- reduced range in the presence of radio frequency interference;
- spontaneous blocking of individual circuits during the summer heat;
- the ability to intercept an encrypted signal with a code grabber;
- decrease in the range of the connector over time.
Key fob functionality
- vibration alerts;
- automatic backlight;
- sound signals about messages from the car;
- full programming of security system functions;
The magicar system is also equipped with a remote engine start function. Logicar is fully compatible with all types of engines, both gasoline and diesel. It also works with different types of gearboxes.
Just like other models of the Sherkhan brand, the Scher Khan Logicar 2 security system is protected by PIN code authorization technology to confirm the deactivation of the alarm. This approach provides a 100% guarantee against unauthorized access of an intelligent type, just as against the possibility of opening by stealing a key or key fob from the owner of the vehicle.
When this function is active, pressing the “disarm” key on the key fob is accompanied by the magicar car alarm switching to the PIN code entry mode, which is naturally known to one owner. Only after the password is received will the Logicar system disable the protection and unlock all the mechanisms of the machine. The code itself, entered when requesting a PIN code, can be changed at any time.
How to install an alarm?
In accordance with the installation manual, the system is installed on a vehicle with the battery disconnected. First, the user must deactivate the ignition, as well as all electrical equipment in the car.

Connection procedure
Guide for installing and connecting anti-theft systems Sherkhan Logicar 3 and 2:
- First, the microprocessor module is installed. Installation is carried out in the most hidden place of the cabin, maximally protected from moisture and other external factors. Fixation is carried out on a flat surface using self-tapping screws or double-sided tape. There should be no electronic devices in the installation location as this may affect the functionality of the module.
- The siren is installed in the engine compartment; a bracket for fixing it is pre-installed. The device is located in the place most protected from elevated temperatures. There should be no engine block near the siren, as well as metal surfaces adjacent to it. The device should be positioned with the connector facing down to eliminate the possibility of moisture accumulation inside. If extension of wires is required, then all cable contacts are connected in the cabin to prevent their oxidation.
- If the engine autostart option is used, some adjustments will need to be made after installing the microprocessor. Under the sliding cover of the control module there is a block closed by a conductor loop. If the car is equipped with a manual transmission, then you do not need to touch it; if it is automatic, then the cable must be cut.
- The transceiver is mounted on the inside of the windshield, the surface of which is previously cleaned and degreased. Fixation is carried out using glue or double-sided tape. The wire from the antenna module is routed to the microprocessor unit under the decorative trim of the interior.
- The engine temperature sensor is installed in the engine compartment, on the cylinder head or a metal surface adjacent to it.
- The impact controller is located inside the vehicle, in the central part of the body. A flat metal surface is used for fastening; fixation is made using self-tapping screws.
- A limit switch is installed on the hood or tailgate, the installation of which is not allowed on gutters. Next, the wire from the device is laid to the control module. If additional limit switches were purchased, they are installed on the car door.
- The “Valet” service button must be placed so that it is installed discreetly, but at the same time there is free access to it. This is due to the fact that during emergency control the user must be in the driver's seat to activate and deactivate the ignition. For additional camouflage, the button can be wrapped with electrical tape of a standard color (black or blue).
- After installation, all alarm components are connected to the microprocessor module. All high current circuits are protected by appropriately rated fuse devices.

How to set up the key fob?
Performing all alarm functions of Sherkhan Logicar 2 and 3 is possible only after entering the code about the communicator into the microprocessor memory.
The process of binding a pager is done as follows:
- Vehicle protection mode is disabled. The key is inserted into the lock and turned to activate the ignition. At the same time, you need to hold down the button to enter the service mode for two seconds.
- The vehicle lights will flash. Within five seconds after this, you must click on the “Jack” button again. The hazard warning light will blink twice and the status LED will remain lit continuously.
- On the key fob to be registered, the first control element is pressed. Information about the communicator code will be entered into the microprocessor memory. The vehicle's hazard lights will flash once.
The rest of the pagers are programmed in the same way. In total, the control unit allows you to register no more than three key fobs. If the microprocessor memory becomes full, the lights will blink twice and the system will exit the binding menu.

Programming Sherkhan Logicar 3 and 2 options
To program the anti-theft system operation options, perform the following steps:
- Auto protection is disabled. When the ignition is turned off, controls 1 and 4, 2 and 4, or 3 and 4 are simultaneously pressed for 2 seconds. Depending on the selected combination of buttons, different programming menus are entered. If the setup mode is successfully activated, the alarm will sound like a siren and lights.
- Using the fourth key, you select a function that is included in the menu. The number of “clicks” must correspond to the option number. Each time you press a key, the alarm is triggered by a siren and lighting devices.
- Then you need to wait about three seconds until the alarm reads the option number and activates it. In confirmation, short siren signals are heard. Their number must correspond to the option number.
- Using the controls, you select the required parameter. To assign a base value to an option, click the first button. The remaining keys are used to select additional settings. If an error is made during programming, the setup steps are performed from the beginning.
- After the parameters are set, you must wait four seconds. The alarm should leave the settings menu. The siren will sound once as confirmation.
If you need to reset all parameters of the security system to factory settings, perform the following steps:
- When the ignition and security systems are turned off, the first and fourth keys “click” simultaneously. The alarm will enter the setup menu.
- The third pager button is pressed three times. With each “click” the system is triggered by lights and a siren.
- Over the next five seconds, the alarm parameters will be reset to factory values. If the reset is successful, three beeps will sound and the alarm will sound.
An example of setting up the “Pit-Stop” option, in which the user can turn on security on a car with the power unit running:
- The vehicle stops in place. The gearbox lever is moved to the neutral speed position if the car has a manual transmission. If there is an automatic transmission, the selector is set to “Parking” mode. The handbrake lever is raised and the pedal is released.
- The second key of the communicator is pressed for two seconds. This will turn on the ignition support system and the pager will emit a double beep. At this moment, the timer mode starts.
- The key is removed from the ignition switch. The power unit will continue to function.
- The driver leaves the cabin and turns on the security function. The engine will remain running, but the starter power circuit will be blocked.
How to enable and configure autorun?
When the engine starts automatically, the operation of the power unit is controlled by tachometer signals; to configure them, the following steps are performed:
- The machine security function is disabled. The power unit starts.
- The setting button is pressed for 2 seconds until the machine lights blink.
- The key is released and pressed again for four seconds. If configured correctly, the car's hazard warning lights will blink once. Otherwise there will be three blinks.
The implementation of automatic engine start on a vehicle with a manual transmission is possible only after setting up the box reservation option.
To do this, carry out the following actions:
- The car stops, the brake pedal is depressed. The gear selector is moved to neutral. The parking brake lever is lifted and the pedal is released.
- The ignition in the car is turned off, the key is removed from the lock.
- Over the next two minutes, the user leaves the car and turns on the security mode (he must lock all the doors).
- After activation, the power unit should stall. If the Turbo Timer option is enabled, the engine will not stop.
To configure autorun by timer, perform the following steps:
- The system programming menu is entered. The required time to start the power unit is set.
- To activate the option, you need to simultaneously press the second and fourth buttons on the communicator.
If you need to remotely start the engine on command, then the second pager key is pressed for two seconds. After a successful start, a corresponding indicator will appear on the key fob screen, as well as a countdown display until the engine stops.
How to turn off the alarm?
In emergency mode, disabling the Sherkhan Logicar 3 anti-theft system without a programmed password is done as follows:
- The key opens one or more car doors. The security complex will begin to play alarm signals.
- Within four seconds, the key in the lock is turned to the “On” position. You do not need to crank the engine with the starter to start.
- The service mode activation button is pressed for two seconds. If all actions are performed correctly, the alarms will turn off.
- Within 5 seconds, the key is pressed again, only briefly, without pressing. The siren will sound once, this will turn off the ignition circuits and the starter mechanism. The car's security will turn off.
If you have a personal password, disabling the alarm is done as follows:
- The door opens and the ignition system turns on. There is no need to start the power unit.
- The button to enter the service mode is pressed for two seconds. This will temporarily deactivate the alarm.
- Within 5 seconds, the key is briefly pressed once. The lighting devices and LED status indicator will blink.
- Over the next four seconds, the first character of the personal password is entered. The service key is used to indicate the code, but the pause between presses should be no more than 1.5 seconds. The number of “clicks” must correspond to the first digit of the code; it can be in the range from 1 to 4.
- To confirm successful entry, the signaling light will blink along with the diode. The light will then go into rapid flashing mode.
- The remaining characters of the password are entered in the same way. If the actions are performed correctly, the siren will sound twice, and the alarm light will also flash. If one of the items is completed incorrectly, an alarm will sound.
Key fob functionality
- vibration alerts;
- automatic backlight;
- sound signals about messages from the car;
- full programming of security system functions;
The magicar system is also equipped with a remote engine start function. Logicar is fully compatible with all types of engines, both gasoline and diesel. It also works with different types of gearboxes.
Just like other models of the Sherkhan brand, the Scher Khan Logicar 2 security system is protected by PIN code authorization technology to confirm the deactivation of the alarm. This approach provides a 100% guarantee against unauthorized access of an intelligent type, just as against the possibility of opening by stealing a key or key fob from the owner of the vehicle.
Main keychain
When this function is active, pressing the “disarm” key on the key fob is accompanied by the magicar car alarm switching to the PIN code entry mode, which is naturally known to one owner. Only after the password is received will the Logicar system disable the protection and unlock all the mechanisms of the machine. The code itself, entered when requesting a PIN code, can be changed at any time.
Possible malfunctions and their elimination
Problems that can occur in the operation of the Sherkhan Logicar 3 alarm system, as well as ways to solve them:
- If there is a physical impact on the body, the alarm does not emit warning or alarm signals. The reason is a poor connection of the shock sensor or its incorrect setting. To fix the problem, you should increase the sensitivity parameter of the controller and make sure that it is connected to the power grid. If the quality of the contact is poor, then the connector must be cleaned and the integrity of the electrical wiring checked.
- Sending alarm messages to the communicator without information about the activation of the security zone. The duration of the alarm is too short to determine the cause. The problem may be that the sensitivity of the shock controller is too high; the operating parameter should be reduced.
- Lack of alarm response to sending commands from the key fob. The cause of the problem may be that the power supply installed in the pager is low. Sometimes the fault lies in the lack of contact at the battery terminal clamp. To eliminate the cause, you should check the tightness of the terminals and also replace the batteries in the pager. If the reason is desynchronization of the communicator and the control unit, then the device must be re-registered into the module’s memory. The problem may be the presence of interference, then to disable the security you need to use emergency deactivation or move the remote control closer to the transceiver.
- Arbitrary deactivation of the vehicle protection mode. Either the shutdown button is pressed in the user's pocket, or the Hands Free option is enabled.
- No warning signals when the alarm is activated or deactivated. The cause of the problem may be an incorrect connection or failure of the signal relay. The latter is located in the microprocessor module. It is necessary to check the operation of the part and replace it if necessary.
- The execution of options is not displayed on the communicator display. When you press the controls, the pager's communication indicator with the transceiver blinks. The cause of the problem is usually the failure of the quartz element installed on the key fob transmitter. The device will need to be repaired or replaced. If this problem occurs, it is recommended to check the operation of the alarm using an additional pager.
Cryptographic strength Sherkhan
At the moment, systems of the Logicar families (except for series with the suffix i, but not iS!) and Magicar (up to the 13th model) are not considered crypto-resistant, which is confirmed by both theft statistics and tests of independent publications. In the case of a typical installation, if the owner (like most of them) does not bother to read the operating instructions, the resistance of the alarm to hacking is reduced catastrophically, since without the user specifying a PIN code for disabling the alarm, the thief can disable the alarm mode by two presses of the Valet button, which the creators of Scher-Khan persistently place it in the most visible place - in the LED module.
In Slave mode, outdated Scher-Khan systems do not have additional validation, that is, if the code of the standard radio key fob is cracked, they are completely deactivated, without checking the eligibility of access to the car.
A common problem with Scher-Khan systems that does not allow the implementation of full-fledged anti-theft systems on their basis is the extreme primitiveness of the start-up interlock mechanism: the installer has at his disposal only one built-in interlock relay (absent on a number of systems) and an additional low-current output to an external relay. The ability to assemble modular complexes, connect wireless blocking relays, or indirectly block the start via the CAN bus is not available in current Scher-Khan systems.
In addition to the ease of deciphering the code message, which the proprietary Magic Code communication protocol of all generations suffers from, it also has a proprietary flaw that is very familiar to owners of Logicar 1-3 alarms - the central alarm unit often loses synchronization with the key fob, ceasing to perceive commands coming from it.

Using the example of the Logicar 1 system, which appears most often in customer requests:
- Disarm the car and turn on the ignition.
- Briefly press the “Valet” button on the LED indicator housing, then hold it until the LED switches to constant lighting mode.
- Press button 1 on each key fob in the kit one by one; the command entry should be confirmed by the blinking of the LED.
- Wait 5 seconds or turn off the ignition.
It must be remembered that in the process of programming key fobs, previously stored ones are erased, so you need to register both the main one (which usually loses synchronization) and the additional one at a time.

The engine started, but it doesn’t show on the key fob
If the car was started not from an additional key fob, but from the main one, and incorrect information is displayed on it, then you should look for an error made when installing the alarm system.
Check that each connector on the main module is connected correctly. If there is no malfunction, contact a specialist.
Anti-theft systems are constantly being improved, protecting your car from break-ins and theft.
This is a necessary security measure even for those drivers who leave their cars in garages or paid parking lots; even they do not always save them from theft.
ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"
Thus, the Scher-Khan company offers several versions of protection systems: MOBICAR, UNIVERSE, MAGICAR, LOGICAR. All of them have the ability to configure auto-start alarms and provide a high level of protection for your car against theft.
