BLE-42 Replacement Immobiliser

How the system works.

After the ignition switch has been switched off:

Once the ID-Tags are out of range the immobiliser wil automatically arm, meaning the car cannot be started. The arming occurs 35 seconds after the ID-Tag is out of range which is 10Mtrs approx. Once out of range the 'Opration LED' will constantly flash indicating the immobiliser is active.

Once the ID-Tag is in range the immobiliser will disarm allowing the vehicle to be started, disarming occurs 5 seconds after the ID-Tag is in range, for disarming is 5Mtrs approx. The 'Operation LED' will stop flashing,
