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. 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. 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 10‑32 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 13‑8 or Roadside Assistance Program (Mexico) on page 13‑10.
