PASS-Key® III Operation Your vehicle is equipped with the PASS-Key® III (Personalized Automotive Security System) theft-deterrent system. When the PASS-Key® III system senses that someone is using the wrong key, it shuts down the vehicle's starter and fuel systems. The starter will not work and fuel will stop being delivered to the engine. Anyone using a trial-and-error method to start the vehicle will be discouraged because of the high number of electrical key codes. If the SECURITY message is shown on the Message Center when trying to start the vehicle, the key may have a damaged transponder. See "PASS-Key® III Security Message" under Message Center on page 225. Turn the ignition off and try to start the vehicle again. If the engine still does not start, and the key appears to be undamaged, try another ignition key. At this time, you may also want to check the fuse. See Fuses and Circuit Breakers on page 463. If the engine still does not start with the other key, your vehicle needs service. If your vehicle does start, the first key may be faulty. See your dealer who can service the PASS-Key® III to have a new key made. PASS-Key III is a passive theft deterrent system. This means you do not have to do anything different to arm or disarm the system. It works when you insert or remove the key from the ignition. ® 125
