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. This means nothing special needs to be done to arm or disarm the system. It works when the key is inserted or removed from the ignition. 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. 2-19
