Brief description, anti-theft alarm: Immobilization

The immobilizer prevents the car starting if the wrong key is used. The fuel supply is shut off and the starter motor relay blocked. The car key contains a transponder with a unique identification code which is received by a receiver unit. The receiver is located in the ignition lock.

The receiver that is connected to TWICE sends the code to TWICE, which is programmed to recognize the car keys. If the correct key is inserted in the ignition switch (ignition position ON), the engine can be started. If a faulty transponder or one Which does not belong to the car is used, "KEY NOT ACCEPTED" will appear on the SID display.

In the event of a fault in the receiver unit or the transponder, the car key can be used to mobilize the car instead. The car will be mobilized if a button on the remote control is pressed after turning the ignition to the ON position.
