TELTONIKA Immobilizer Purpose

The purpose of the immobilizer "TELTONIKA IMB5" is the prevention of the car theft.

• The driver is identified when the person with the active paired ID card comes inside the communication area.
• If the person has no ID card, the immobilizer regards the vehicle is under unauthorized use and transfers the signal for engine immobilization.
• The system supports up to 5 ID cards.

The Set and Components

The immobilizer includes:

• System Unit: An electronic module hidden inside the vehicle.
• ID Card: An electronic key that should be kept in the driver's pocket or handbag.
• Buzzer: For acoustic signals and status warnings.
• LED Indicator: For visual status information.

The ID Card

The ID card is not intended for use as a remote key fob and shall be kept separately from the car keys.

ID Card Modes

You can change the ID card mode by pressing and holding the button:

• Active Mode (Green LED): The card constantly communicates with the System Unit. Recommended for daily use.
• Passive Mode (Orange LED): The card only communicates when the button is pressed. Recommended for long-term storage or battery saving.
• OFF Mode (Red LED): The card is completely turned off.

Battery Replacement

• Battery type: 3V CR2032.
• Life span: It is recommended to replace the battery every 12 months.
• Low Battery Warning: When the ignition is turned ON, the system warns by a series of 4 double buzzer signals if the ID card battery is low.

Anti-Carjack Protection

If the ID card signal is lost while the ignition is ON (e.g., if the driver is forced out of the car):

1. The system starts a countdown (60s or 120s depending on settings).
2. The buzzer will warn with increasing frequency.
3. Finally, the engine will be immobilized.
