PASS-Key® III uses a radio frequency transponder in the key that matches a decoder in your vehicle. PASS-Key® III Operation Your vehicle is equipped with PASS-Key® III (Personalized Automotive Security System) theft-deterrent system. PASS-Key® III is a passive theft-deterrent system. The system is automatically armed when the key is removed from the ignition. You do not have to manually arm or disarm the system. The security light will come on if there is a problem with arming or disarming the theft-deterrent system. PASS-Key III® uses a transponder in the ignition key that matches a decoder in the vehicle. When the PASS-Key® III system senses that the wrong key has been inserted into the ignition, it shuts down the vehicle's starter and fuel systems. The starter will not work and fuel will stop flowing to the engine. If someone tries to start the vehicle again with the wrong key, the vehicle will not start. Anyone using a trial-and-error method to start the vehicle will be discouraged to do so because of the high number of electrical key codes. When trying to start the vehicle, if the engine does not start and the STARTING DISABLED warning message on the Driver Information Center (DIC) comes on, there may be a problem with your theft-deterrent system. Turn the ignition off and try again. 2-22
