Teltonika IMB5 — Professional Vehicle Immobilizer with Contactless RF Driver Identification


The Teltonika IMB5 is a trusted, professional-grade vehicle immobilizer built for both standalone vehicle security and integration with the Teltonika GN7 and GN8 alarm systems. Unlike basic relay-based immobilizers, the IMB5 uses contactless 2.4GHz RF communication between a discreet system unit hidden inside the vehicle and a compact ID card carried by the authorised driver — no physical contact or key fob button pressing required. The driver simply needs to be within range and the vehicle automatically recognises them as authorised.

Automatic engine blocking activates 40 seconds after ignition is switched off, ensuring continuous protection every time the driver leaves the vehicle without any manual arming step. If an unauthorised person attempts to start the engine, the IMB5 prevents it — and a configurable anti-carjack mode adds an additional layer of protection against theft while the vehicle is in motion.

As an official Teltonika distributor in the UK, Tracking Hardware UK stocks the IMB5 and ships directly from our London warehouse — with volume pricing available for vehicle security installers and fleet operators.


Key Features


  • Contactless 2.4GHz RF driver identification — the ID card communicates wirelessly with the hidden system unit at up to 5 metres range, automatically authorising the driver without any physical interaction

  • Automatic engine immobilisation — engine blocking activates automatically 40 seconds after ignition is switched off, providing continuous protection without any manual arming required

  • Driver recognition — the system identifies authorised drivers automatically when the ID card is within range, immediately blocking the engine if an unrecognised person attempts to start the vehicle

  • Up to 5 RF keys supported — up to 5 ID cards can be programmed simultaneously, allowing multiple authorised drivers to be registered for fleet or family use

  • Anti-carjack mode — advanced two-type anti-carjack protection disables the engine if the vehicle is stolen while in motion, providing protection beyond standard stationary immobilisation

  • 4-digit PIN code override — a configurable PIN code allows the vehicle to be started without the ID card in emergency situations, with the ability to change the PIN at any time

  • Double circuit immobilisation — two independent immobilisation circuits provide a higher level of security than single-circuit systems

  • Passive arming — automatic immobilisation activates after 40 seconds without requiring driver action, eliminating the risk of forgetting to arm the system

  • Status LED indicator — clear visual indication of system status for quick confirmation during installation and operation

  • Audio buzzer — provides audible feedback for system events and alerts

  • Compatible with GN7 and GN8 — integrates directly with the Teltonika GN7 Anti Theft Plus and GN8 Anti Theft Pro alarm systems for a complete layered vehicle security solution

  • Negative and positive door input — compatible with both negative and positive polarity door trigger signals for flexible installation across different vehicle types


Typical Use Cases


Ideal for fleet operators requiring authorised driver-only vehicle access, car rental and leasing companies preventing unauthorised vehicle use, high-value private vehicle protection beyond factory alarms, taxi and private hire operators controlling driver access to specific vehicles, integration with the Teltonika GN7 or GN8 for a complete vehicle alarm and immobilizer solution, and any application where automatic passive immobilisation without driver action is required.


Frequently Asked Questions


How does the IMB5 contactless identification work?

The IMB5 system unit is hidden inside the vehicle during installation. The authorised driver carries the small ID card in their pocket or bag. When the driver enters the vehicle and is within the 5 metre communication range, the system unit automatically recognises the ID card via 2.4GHz RF communication and disarms the immobilizer — no button pressing, key fob or physical contact required.


What happens if I lose my ID card?

If the ID card is lost, the PIN code override allows the vehicle to be started using a 4-digit code without the card. New ID cards can be programmed by the installer. Contact us for guidance on reprogramming.


Can the IMB5 be used with the Teltonika GN7 or GN8 alarm?

Yes — the IMB5 is designed to integrate with the Teltonika GN7 Anti Theft Plus and GN8 Anti Theft Pro alarm systems, providing a complete combined alarm and immobilizer solution with multiple layers of vehicle protection.


How many drivers can be registered on the IMB5?

Up to 5 RF ID cards can be programmed simultaneously, making the IMB5 suitable for shared vehicles, fleets and family use where multiple authorised drivers need access.
