Car alarm Sherkhan Logicar 5i is one of the most popular solutions for protecting mid- and premium-class vehicles. This model combines advanced security functions, convenient control via a key fob and mobile application, as well as flexible settings for the individual needs of the owner. However, even the most “smart” alarm system requires correct installation, competent configuration and an understanding of the principles of operation - otherwise the risk of false alarms or, worse, an incorrect reaction to a real threat increases significantly.

In this guide we will look at all stages of working with Logicar 5i — from installation and first startup to fine-tuning sensors and integration with additional modules. We will pay special attention to the typical mistakes that owners make during self-installation, as well as the nuances of operation that are not written about in the standard instructions. If you plan to install an alarm system yourself or just want to understand its capabilities, this article will help you avoid costly miscalculations.

1. Equipment and preparation for installation

Before installation Sherkhan Logicar 5i Be sure to check the completeness of the kit. Standard delivery includes:

  • 🔑 Main keychain with LCD display (2 pieces in the Premium set)
  • 🚗 Central control unit (brain of the system)
  • 🔊 Self-powered siren (12V)
  • 📡 Antenna module (for communication with the key fob)
  • 🔧 Set of wires and connectors for connection
  • 📄 Brief instructions in Russian
  • 🔋 Additional sensors (shock, tilt - depending on the configuration)

The absence of at least one element is a reason to contact the seller. It is especially critical to check the presence antenna module: without it, the communication range of the key fob with the alarm will be reduced to 10–15 meters.

Also prepare your tools:

  • 🔧 Screwdriver set (phillips, flat)
  • 🔨 Multimeter to check voltage
  • 🧲 Electrical tape and heat shrink tubing
  • 🔌 Soldering iron (if you need to connect to the CAN bus)
⚠️ Attention: If your car is equipped with a system Keyless Go or immobilizer with dynamic code, for correct operation Logicar 5i An additional immobilizer bypass module may be required (for example, Sherkhan BP-03). Without it, the alarm will not be able to start the engine remotely.

2. Connection diagrams and installation of the central unit

Successful installation Sherkhan Logicar 5i 80% depends on the correct placement of the central unit and routing of wires. Follow these principles:

  • 📍 Block location: Choose a hidden location under the dashboard, but not near sources of heat (such as a heater) or vibration (such as speakers). Optimally - behind the glove compartment or under the steering column.
  • 🔌 Power connection: Red wire (+12V) connect directly to the battery through a fuse (10–15A). Black (GND) - to the car body, having previously cleaned the metal.
  • 🔄 CAN bus: If your car supports CAN protocol, connect the wires CAN-H and CAN-L to the OBD-II diagnostic connector (usually pins 6 and 14).

To connect to the standard alarm system or central locking, use the relays included in the kit. The connection diagram depends on the car model. For example, for Toyota Camry 2018+ you will need:

Alarm wire Color Connection to car
Central locking (locking) Green/black To the lock wire on the driver's door (LOCK)
Central locking (unlocking) Green To the lock wire on the driver's door (UNLOCK)
Door sensor White/black To the driver's door switch (DOOR)
Starter (remote start) Red/yellow To the starter wire after the ignition switch

If you are not sure about the wiring diagram for your car model, use search by VIN code on the website Sherkhan or contact an electrician. Incorrect connection to the CAN bus can damage the standard electronics!

3. Setting up the key fob and basic functions

After installation, it is necessary to synchronize the key fobs with the central unit. To do this:

  1. Turn on the ignition (do not start the engine).
  2. Press and hold the button Valet (service) on the central unit for 10 seconds until 3 siren signals sound.
  3. Press the button on the key fob I (close) - 1 confirmation signal should sound.
  4. Repeat step 3 for the second key fob (if available).
  5. Turn off the ignition. Synchronization is complete.

Now you can configure the basic settings:

  • 🔕 Sensor sensitivity: Hold III on the key fob for 3 seconds, then select the level (1–5) using the buttons I/II. For the city, 2-3 are enough, for street parking - 4-5.
  • 🚗 Auto start based on temperature: In the key fob menu (Menu → Settings → Autorun) set the threshold, for example, +5°C or -10°C.
  • 🔋 Economy mode: Activated in the key fob settings (Menu → Energy saving). Useful for long-term parking (reduces current consumption to 20 mA).
⚠️ Attention: If after setting up the key fob stops responding to commands, reset it to factory settings: press and hold I + III for 10 seconds. After this, resynchronization will be required.

Critical Feature Logicar 5i: When Panic mode is activated (hold II 3 seconds) the siren will work until you press any button on the key fob or insert the key into the ignition. This can drain your battery in 2-3 hours!

💡

If the key fob starts to “glitch” (does not show the temperature, does not respond to pressing), remove the battery from it for 10 minutes, then insert it back. In 80% of cases this solves the problem without reflashing.

4. Remote engine start: settings and nuances

One of the key features Sherkhan Logicar 5i — remote engine start. For it to work correctly, you must:

  1. Make sure the car is equipped electronic control unit (ECU) with autorun support. An additional module will be required on the mechanical box Sherkhan BP-02.
  2. In the key fob menu (Menu → Autorun) install:
    • Start timer (eg every 2 hours)
    • Temperature threshold (for example, -15°C)
    • Engine running time (recommended 10–15 minutes)
  • Check settings immobilizer. If it is not bypassed, the engine will not start.

    • To start from the key fob:

    • Click II (open) + III (trunk) simultaneously for 2 seconds.
    • The engine will start if all conditions are met (neutral gear, handbrake engaged, etc.).

    Typical problems and solutions:

    Problem Possible reason Solution
    Engine won't start The immobilizer is not bypassed Install module BP-03 or BP-05
    Start works, but engine stalls Incorrect warm-up time setting Increase operating time in key fob settings
    Key fob shows error E4 Low battery voltage Charge the battery or check the generator
    ⚠️ Attention: On vehicles with turbocharged engines It is not recommended to set the autorun operating time to more than 10 minutes. This can lead to overheating of the turbine due to lack of cooling at idle speed.
    How to bypass the immobilizer without the BP-03 module?

    Theoretically, it is possible to connect a second ignition key with a chip in the area of the immobilizer antenna (usually around the ignition switch). However, this is not safe: if the key is lost or stolen, an attacker can easily steal the car. In addition, this method often leads to ECU errors.

    5. Integration with Sherkhan Mobile mobile application

    To remotely control the alarm via a smartphone:

    1. Download the app Sherkhan Mobile (available for Android and iOS).
    2. Register or log in to your account.
    3. Add device:
      • Enter the serial number of the central unit (located on the sticker).
      • Confirm your addition via SMS code.
  • Set up notifications for alarms, low battery, etc.

    • Application features:

    • 📱 Remote engine start (if the option is enabled in the unit settings).
    • 📍 Vehicle location tracking (requires GPS module Sherkhan GPS).
    • 🔔 Alarm history indicating the cause (impact, door opening, etc.).
    • 🔋 Battery voltage monitoring.

    If the application does not connect to the alarm:

    • Check that the car is turned on GSM module (if included).
    • Make sure that the SIM card in the module is active and has enough funds (balance of at least 50 ₽).
    • Reboot the alarm unit by disconnecting and reconnecting the power.
    💡

    For stable operation of the mobile application, use a SIM card with a tariff that supports data transfer (GPRS/3G). Cards with payment “per minutes” (for example, Tele2 “For calls”) are not suitable.

    6. Typical errors and their elimination

    Even with proper installation, owners Sherkhan Logicar 5i face typical problems. Here are the most common:

    • 🔋 The alarm is draining the battery:
      • Cause: Incorrect power connection or short circuit in the wires.
      • Solution: Check the leakage current with a multimeter (should be no more than 50 mA). Turn off the alarm unit and repeat the measurement.
    • 🚨 False alarms of the shock sensor:
      • Cause: Sensitivity is set to maximum or the sensor is not securely fastened.
      • Solution: Reduce sensitivity to 2–3 and fix the sensor on a hard surface (for example, on the body under a dashboard).
    • 📵 The key fob does not receive a signal:
      • Reason: The key fob battery is low or the antenna is damaged.
      • Solution: Replace the battery (type CR2032) and check the integrity of the antenna wire.

    If the alarm stops responding to commands at all:

    1. Check the line fuse +12V.
    2. Make sure the service button Valet not pressed (this disables security).
    3. Reset the unit to factory settings by turning off the power for 30 seconds.

    To diagnose errors, use service menu keychain:

    1. Clamp I + II + III for 5 seconds.
    2. An error code will appear on the screen (for example, E2 — problem with the door sensor).
    3. For decoding of codes, see the instructions or on the website Sherkhan.
    💡

    If the alarm goes off at night for no apparent reason, check to see if there are any trucks or trains passing nearby. Low frequency vibrations may trigger the shock sensor. The solution is to reduce the sensitivity or install the sensor on rubber shock absorbers.

    7. Firmware update and factory reset

    The manufacturer regularly releases firmware updates for Logicar 5i, fixing bugs and adding new features. To update:

    1. Download the latest firmware from official website (section "Support").

    3. Insert the card into the slot of the central unit (located under the cover).
    4. Turn on the ignition - the update will begin automatically (the siren will emit 5 beeps).
    5. Wait for it to complete (about 2-3 minutes) and reboot the unit.

    If the update is unsuccessful (the siren beeps continuously):

    • Remove the MicroSD card.
    • Turn off the unit's power for 1 minute.
    • Repeat the procedure with a new memory card.

    To perform a full factory reset:

    1. Turn off the ignition.
    2. Press and hold the button Valet.
    3. Turn on the ignition without releasing Valet.
    4. After 3 siren signals, release the button - the settings are reset.
    ⚠️ Attention: Resetting settings removes all user settings, including linked key fobs and sensor settings. After the reset, you will need to resynchronize the key fob and adjust the sensitivity.

    FAQ: Frequently asked questions about Sherkhan Logicar 5i

    Can Logicar 5i be installed on a car with an automatic transmission?

    Yes, but for this you need to connect an additional module Sherkhan BP-03 or BP-05, which simulates the presence of a key in the ignition switch. Without this module, remote engine starting will not work. Also make sure that the mode is selected in the alarm settings AT (Automatic).

    How to turn off the siren sound when arming/disarming?

    Press and hold the button III on the key fob for 3 seconds, then select the mode No sound (speaker icon with a strikethrough). You can also turn off sound signals in the key fob menu: Menu → Settings → Sound → Quiet mode.

    Why does the key fob show error E3?

    Error E3 indicates a problem with the temperature sensor. Most often this is due to a broken wire or a malfunction of the sensor itself. Check the connection of the sensor to the central unit (usually a white wire with a black stripe). If the wire is intact, replace the sensor.

    How to set up auto-start on alarm?

    In the key fob menu, go to Menu → Autorun → Alarm clock. Set the time (eg 7:00) and days of the week. The engine will start 10-15 minutes before the specified time if the temperature is below the specified threshold.

    Can I connect a rear view camera to the Logicar 5i?

    Yes, but this will require an additional module Sherkhan Video and compatible camera with resolution up to 720p. The camera will be activated when reverse gear is engaged or upon command from the key fob. Please note that video is recorded only when an alarm is triggered (not in continuous mode).
