Keys, Doors, and Windows You do not have to manually arm or disarm the system. The security light comes on if there is a problem with arming or disarming the theft-deterrent system. When the PASS-Key III+ system senses an incorrect key, the vehicle does not start. 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 engine does not start and the security light on the instrument panel comes on when trying to start the vehicle, there may be a problem with the theft-deterrent system. Turn the ignition off and try again. If the engine still does not start, and the key appears to be undamaged, try another ignition key and check the fuses. See Fuses and Circuit Breakers on page 10‑30 for additional information. If the engine still does not start with the other key, the vehicle needs service. If the 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. In an emergency, contact Roadside Assistance. See Roadside Assistance Program (U.S. and Canada) on page 13‑7 or Roadside Assistance Program (Mexico) on page 13‑9.

The following procedure is for programming additional keys only. If all currently programmed keys are lost or do not operate, you must see your dealer or a locksmith who can service PASS-Key III+ to have keys made and programmed to the system. See your dealer or a locksmith who can service PASS-Key III+ to get a new key blank that is cut exactly as the ignition key that operates the system. 2-15 To program the new additional key: 1. Verify that the new key has a 1 stamped on it. 2. Insert the already programmed key in the ignition and start the engine. If the engine does not start, see your dealer for service. 3. After the engine has started, turn the key to LOCK/OFF, and remove the key. 4. Insert the key to be programmed and turn it to the ON/RUN position within five seconds of the original key being turned to the LOCK/OFF position. The security light turns off once the key has been programmed. 5. Repeat Steps 1 through 4 if additional keys are to be programmed.
