MiBlock Immobiliser | Active Tag Ignition Immobiliser | Car Tracking – Phantom Ltd


We know

Equipped with the MiBlock Active Tag, you can be sure that your vehicle cannot be started by anyone that is not authorised to do so, without having to use a large, cumbersome device attached to the steering wheel, for example.

Feel safe with the MiBlock Active Tag immobiliser

The MiBlock Active Tag is our intelligent ignition immobilisation device. It can be installed on its own to work on a stand-alone basis, but can also be coupled to the Mi50 vehicle tracking system. When used together with the Mi50 system, the immobiliser will also be activated after GSM jamming has been detected (jamming is often employed by thieves in an attempt to prevent the vehicle from being tracked). After jamming, the Active Tag or Emergency Key will be needed – in addition to the ignition key – to start the vehicle.

The combination of the Mi50 system and the MiBlock Active Tag immobiliser fully meets requirements set by insurers and car lease companies for vehicle security systems. When using the MiBlock Active Tag immobiliser on its own, your security system will be Thatcham accredited.

Mechanism of the MiBlock Active Tag

When the engine is shut off, the immobiliser will automatically reactivate after a few seconds (as a safety precaution e.g. in the event of temporary engine failure). As soon as the immobiliser is activated, the LED light will flicker and the vehicle’s engine control unit (ECU) will be intercepted in multiple places, making it impossible to start the engine. When the MiBlock Active Tag detects an Active Tag nearby (within 5 metres), the immobilisation device is then deactivated again.
