Characteristics of the security system

Another interesting feature of the scher khan logicar 2 is the time synchronization algorithm of the alarm key fob and the head unit (reception and execution of the command is possible only if they completely coincide. This algorithm is described in more detail by the standard instructions.
The latest error correction system of the scher khan logicar 2 allows the radio path to operate reliably even in the presence of a lot of interference.The communication range of magicar is about five hundred meters, notifications can be delivered to the owner at a distance of up to one and a half kilometers.

scher khan logicar 2 comes with a key fob equipped with a TFT screen, on which the vehicle status and a number of other service data are displayed using icons and indicators:

• feedback signal quality;
• battery voltage;
• air temperature inside the car;

The Scher-Khan LOGICAR 2 car alarm is a security system that supports two-way data exchange with a protected vehicle through a communication channel protected by a crypto-resistant algorithm. A key fob with a large LCD display provides the owner with comprehensive information about the condition of the car at a distance of up to 1.5 km. The system has an autostart function and can control the start of any engine based on several events or a direct command from the key fob.

Functions and Features

The integrated CAN and K-LINE digital bus adapter allows the SCHER-KHAN Logicar 5i to be perfectly integrated into the on-board electronics of the most modern vehicles. With a minimum number of connections, SCHER-KHAN Logicar 5i allows you to mobilize all the security and service potential that was laid down by the automaker. SCHER-KHAN Logicar 5i is equipped with an upgraded modification of the proprietary signal encryption algorithm - MAGIC CODE PRO 3.

Compared to earlier versions, the size of the code message was doubled. In addition, SCHER-KHAN Logicar 5i uses an individual encryption key for each instance of the security system, the radio channels of which are encoded using this algorithm. All these technologies make it possible to effectively repel any intelligent hacking attempts.

SCHER-KHAN Logicar 5i offers an extensive range of service functions, including a TURBO mode with automatic determination of the time required to cool the turbine, a Pit Stop mode that allows you to arm a car with a running engine without a key in the ignition. Additionally, SCHER-KHAN Logicar 5i allows you to implement the automatic engine start function.

Preparing the key fob for use

Before using the scher khan logicar 5i car alarm remote control for the first time, bend the latch holding the battery compartment cover, press the cover and move it away from the antenna. Install a new battery according to the polarity indicated on the case. Close the battery compartment cover. Done, the scher khan logicar 5 keychain can be used.

Energy saving mode

Battery Save Mode technology is designed to reduce energy consumption by the car alarm key fob. In this mode, information about protective zones is not displayed on the LCD screen and the communication range is reduced.

Enabling security mode

Initially, you need to turn off the ignition, close all doors, the engine compartment lid and the trunk. Next, press the I key of the key fob once. The security mode is activated, the power unit is locked and all the locks are closed.

The car will remain in this position until the protection is turned off. After which the protective mode will be turned off and all locks, including the trunk and hood lid will open

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:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.

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.

Conclusion

Car alarms Sherkhan Magikar 4, Logikar 4 are mid-level security systems with wide functionality. At the moment, Sherkhan Magikar 4 is no longer relevant; the model has been discontinued from mass production. The main reason is insufficient protection against hacking, interception of pulses, and signal transmission and reception.

A similar fate befell previous modifications, such as Magikar 2, 3, 4. However, at one time, signaling devices were in demand, the technical characteristics were above average.

The most common problems and their solutions

There are a number of problems due to which the Sherkhan alarm system is not set to autostart. These include the following phenomena:

1. After turning off the ignition, the car refuses to stall. To deactivate autostart, you need to open/close the doors. The problem itself is eliminated by performing functions 1-16, which are activated by a button with value 2. Next, you need to turn off the engine by turning the ignition key to the “off” position.
2. The next stage involves enabling the “Valet” service mode by emergency deactivation of the alarm. To fix the problem, you need to hold down buttons 1 and 3 at the same time.
3. If you need to quickly turn off the engine from the pager, hold button 2 long enough.

Characteristics of Scher-Khan Logicar 3 and Scher-Khan Magicar 3

Alarm installation and connection

All diagrams below are provided with installation instructions. Power is supplied to the processor unit through the power connector, or more precisely, through the “red” cord connected to the lock contact “30”. However, the documentation states the following: power for the alarm is supplied from the fuse terminal. But the 30 amp fuse in question is usually present in the starter circuit.

Main unit of the security system

Anyone who thinks that the setup is complete is mistaken. There is an LED installed under the curtain, and it should only light up when the engine is running. If the instructions are not followed, change the alarm setting - set selector “2” to a different position. The “ON” mark corresponds to a high ripple level, the “OFF” mark to a lower one.

Now let's look at how the car alarm is connected to the ignition switch. The Scher Khan Magicar A system has the following feature: it switches the starter circuit as well as the first ignition circuit. If two different circuits are responsible for the ignition process, install an additional relay. The alarm itself will control it by shorting the purple connector cord to ground.

Power connector, connection diagram

The following cables are connected to the ignition switch contacts:

1. ACC terminal – white wire;
2. Terminal “15/1” – green;
3. Terminal “50” – yellow;
4. Terminal “30” or fuse connector is red.

The blocking relay is connected between contact “50” and the connection point of the signaling wire. However, you can do without blocking, but the “green” cord must be connected in any case.

The “green” cable is not only an output, but also a low-current input for a car alarm. Connect it even if you do not implement automatic launch.

Low current inputs and outputs

Using the diagram provided by the basic instructions, you can immediately understand which wires the size lamps are connected to. A relay is installed inside the car alarm housing, and its contacts can switch both “positive” and “negative” voltage. This is the positive feature of Scher Khan Magicar A.

Signal input connection options

More precisely, you need to use only one wire, which is selected depending on the polarity. This is true if we talk about car alarms of any model, and not just about the Scher Khan Magicar A or Logicar systems.

For some reason, the basic diagram does not show how exactly the first cord of the 9-pin connector is connected. In fact, if we are talking only about Sherkhan A, “minus polarity” sensors are connected to “cord 1”:

Connection diagram, “wire 1”

As you can see, a car alarm can receive data from several switches, but on the condition that each of them is connected to ground. To connect, use 1N4001 diodes, connecting their anodes to the “black” wire. But the power diodes indicated in the diagram must withstand significant current (2-3 Amperes). If you install only low-current diodes, problems will arise that will manifest themselves during long-term operation.

Let us note an important circumstance. The Scher Khan Magicar A system, the connection of which was discussed here, is an alarm system with automatic engine start

But any car alarm equipped with this option must monitor the state of the handbrake or brake lights. Otherwise, during operation, you can observe the following: a car left “in gear” begins to move on its own. Despite this, the alarm system of this model does not have low-current inputs connected to the handbrake micro button or to the brake pedal limit switch.

If autostart is implemented, be sure to cut the gearbox selection loop if you are using an automatic transmission. Otherwise, the car alarm will be able to start the engine even when the gear is engaged.

How to install?

Step-by-step installation algorithm:

Mount the main unit inside the instrument panel. The block is attached to a plastic panel body or a metal load-bearing frame. Double-sided tape or plastic ties are used for fixation. There are no standard fastening points with self-tapping screws on the block. It is recommended to place the unit at a distance from the standard electronic components of the car, which may emit radio interference. Install the antenna. The location is usually the windshield of a car. The antenna elements must be located at a distance of at least 5 cm from metal parts of the body. The antenna unit is located vertically, thereby ensuring maximum communication range

The wire is laid under the headliner and along the front pillars, subject to safety precautions. The manufacturer allows the antenna to be placed secretly, under plastic panels

In this case, the signal level may decrease and the range may be reduced. It is not allowed to install the unit under metal panels that will shield the signal. Stick a status indicator diode on the windshield and lay a signal wire. The diode can be located in a hole made on the plastic elements of the instrument panel or the trim of the front pillars. It is possible to fix the diode in the hole with glue or sealant. Install a siren on the engine side of the engine shield. Lay signal wires from the siren connector to the main unit. When installing a non-standard siren, follow the connection instructions. Modern cars can be equipped with signal switches in the trunk and hood locks. In the absence of such devices, free-standing mechanical limit switches are used. Installation is carried out in a hole made on the body or on a separate bracket attached to the body. The limit switch rod should not interfere with loading cargo into the trunk or maintenance of components and assemblies. Place an impact sensor in the cabin. For installation, standard self-tapping screws, plastic ties or double-sided tape can be used. Install an additional sensor that is used to control interior volume. Check the wiring to the main unit and connect them in accordance with the wiring diagram.

Increased communication range and additional level of code spoofing protection

This car alarm model uses a crypto-resistant coding algorithm

radio signal Magic Code Pro 2, which is distinguished by the use of continuous block-stream encryption of the entire packet of information sent on the air.
time synchronization
mode is used , thanks to which disabling the security mode is possible only if the time on the timers of the key fob and the alarm unit completely coincides.
The system can be controlled at a distance of up to 500
meters, and notifications will be sent to the main key fob at a distance of up to
1500
meters.

More detailed information on working with the security system is contained in the detailed instructions included in the kit.

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:

Connection diagram for Magikar signaling

Information on installing Sher khan security systems, when it comes to the Magikar family, is freely available.

Connecting "Magicars" of the old family

The circuit shown here is suitable for Scher khan magicar systems numbered 9 and less. Scher khan magicar modules of the “old family” are equipped with the same type of connector, which is done to make repairs or even replacements easier. Let us list the main differences between Logikar and Magikar:

• As can be seen from the diagram, to implement autostart, a Scher khan magicar signaling connector with six contacts is used. The Sher khan system of the Logicar family has three additional signal outputs, but here there is one (“purple” cord).
• The Scher khan magicar system can emulate all the circuits passing through the lock. This is not done for Sher khan systems of the Logicar family.
• Options similar to F2-29 were not provided for Scher khan magicar systems. It is possible to connect to the “START/STOP” button, and this will not lead to the need for repairs. But autostart will work every other time.

If the "START/STOP" button is used, and the engine needs to be equipped with autostart, do not buy a Scher khan magicar kit with number 9 or lower. The latter, by the way, is also typical for Starline signaling, unless they belong to new families.

Having studied the reviews, you can understand that the security system called Scher khan magicar is a reliable and durable device. The main unit itself rarely fails, but sometimes it is necessary to repair the key fob. What people get into their hands most often needs repair, and Sher khan keychains are no exception.

Keychain for the “fifth Magikar”

However, the above also applies to other systems, such as Starline, etc.

There is also an opinion that Sherkhans are hacked using a code grabber, since they use a one-way code. Starline, in turn, uses conversational coding, which looks better. We list the signaling models for which code grabbers exist:

• Logicar 1, 2, 3 and 4 (models 2 and 4 are equipped with autostart);
• Any Scher khan magicar alarm system up to the tenth family inclusive, as well as models A, B, C, D, Vegas.

We were talking about Scher khan magicar signaling devices with MAGIC CODE, MAGIC CODE PRO and PRO-2 coding. The “third” magic code has not yet been cracked.

Installation and connection

For Scher-Khan Logicar 4, the installation instructions require the following steps:

1. Preparing the car. Before connecting the alarm, the on-board network must be de-energized. To do this, turn off the ignition and disconnect the battery terminals.
2. Installation of the processor unit. The device is mounted in a place that is inconspicuous to potential criminals, such as behind the dashboard. To do this, remove the decorative trim of the steering column and unscrew the screws holding the shield. The block is placed in a free space and secured with screws.
3. Siren installation. The part is installed in a hidden place. The horn must be turned down. The siren must not be placed near the engine.
4. Installing the Valet button. The part is used for emergency shutdown of the alarm mode, so it must be mounted in a place inaccessible to criminals. The button can be hidden under the standard wiring harnesses and masked with electrical tape.
5. Installation of limit switches. The kit includes 1 controller, which is equipped with the hood or trunk. The remaining switches will have to be purchased separately. To install the parts, holes are drilled on the doors, after which the decorative trims and handles are removed.
6. Installing an engine blocker. The device is embedded in the ignition switch block.
7. Installation of the sensitivity sensor. The part is installed in the middle part of the body. The wiring is routed through holes in the partition separating the engine compartment from the passenger compartment. After installation, adjust the sensitivity of the sensor.

Connection diagram

The system components are connected to the head unit and power source according to the diagrams attached to the instructions. All power circuits are equipped with fuses of the appropriate rating. After connecting the cables, you need to check the functionality of the car alarm.

Logicar 3 car alarm kit

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.

Video: Control and configuration of Scher-khan magicar

Using the example of the Logicar 1 system, which appears most often in customer requests:

1. Disarm the car and turn on the ignition.
2. Briefly press the “Valet” button on the LED indicator housing, then hold it until the LED switches to constant lighting mode.
3. 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.
4. 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.

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:

1. Disarm the car, turn off the ignition, turn off the “Hands-free” mode (see above);
2. Press buttons “1” and “4”, hold them for 2 seconds;
3. A short signal from the “dimensions” and a siren will follow;
4. Press the "4" button 6 times;
5. Wait 4-5 seconds, 6 signals will follow;
6. To use a 4-digit code during operation, press the “2” key, and if you need a two-digit code, press the “3” key;
7. 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:

1. Disarm the car, turn off the ignition;
2. Press buttons “3” and “4”, hold them for 2 seconds;
3. A single signal should follow;
4. Press the key fob corresponding to the first digit;
5. 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:

1. If option "6" is set to "2" or "3", first perform the steps required to disarm without using a code;
2. After the “dimensions” flash, turn the key to dial the value of the first digit;
3. Repeat “step 2” to enter the second digit;
4. 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.

How to install?

The installation procedure is as follows:

1. Assemble all the alarm elements without installing them on the car. In accordance with the diagram, connect the components of the complex to the control unit, and then connect it to the battery. This is done to check the signaling. Having connected the system to the battery, activate and disable the protective function, check the main options. If everything is in order, we proceed to the next stage.
2. Disconnect the car's power supply. The installation of the security system is carried out with the on-board network turned off. Turn off the ignition and open the hood, use a wrench to loosen the alligator clip on the battery, and then disconnect it.
3. Install the control module. A criminal should not have access to it, so the unit is installed in a place hidden from the criminal. You can install the device behind the dashboard. We do not recommend installing a unit under the center console; this is the place criminals check first when breaking into a car. To install the module behind the dashboard, dismantle the trim on the steering column and unscrew the screws securing the control panel. Disconnect the wire connectors from it. In the free space, place the block and lock it in place. You can wrap the device with foam rubber to prevent it from being exposed to vibrations while the car is moving. The unit is attached to the car body or center console using self-tapping screws.
4. A siren is being installed under the hood. It is also advisable to place it in a hidden place. We recommend pointing the device's horn downwards or in the direction of travel of the car. The siren should not be installed in close proximity to the motor, since exposure to high temperatures will damage it.
5. Install the Valet service button. It can be used to activate emergency mode and emergency shutdown of the alarm. Therefore, it must be installed in a hidden place. You can disguise the button in the standard wiring by fixing it on the electrical circuit and wrapping it with electrical tape.
6. Install limit switches. The kit includes only one limit switch, so it can be installed on the hood or trunk lid. The remaining switches must be purchased additionally. To install them on the doors, you will have to make holes if they are not provided by the manufacturer. To do this, use a drill with a cutter. To install the switches, it is necessary to remove the door trim, handles and speakers.
7. Remove the ignition switch trim and install the engine lock relay. The device is connected in accordance with the diagram.
8. The sensitivity sensor is installed inside the car. For installation, it is advisable to choose a location in the central part of the body. You can use a partition separating the car interior and the engine compartment. This device will be responsible for the timely operation of the siren, so setting its reaction is important for the complex as a whole. After installation and connection, adjust the operation of the controller.
