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 instrument panel fuse 12. 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 or a locksmith who can service the PASS-Key III to have a new key made. See "Fuses and Circuit Breakers" in the Index. It is possible for the PASS-Key III decoder to learn the transponder value of a new or replacement key. Up to 10 additional keys may be programmed for the vehicle. This procedure is for learning additional keys only. If all the 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 key: 1. Verify the new key has "PK3" stamped on it. 2. Insert the ignition key in the ignition and start the engine. If the engine will not start see your dealer for service. 3. After the engine has started, turn the key to OFF and remove the key. 4. Insert the key to be programmed and turn it to RUN within 10 seconds of removing the previous key. 5. The security message will turn off once the key has been programmed. It may not be apparent that the security message went on due to how quickly the key is programmed. 6. Repeat Steps 1 through 4 if additional keys are to be programmed. If you are ever driving and the security message comes on and stays on, you will be able to restart your engine if you turn it off. Your PASS-Key III system, however, is not working properly and must be serviced by your dealer. Your vehicle is not protected by the PASS-Key III system at this time. If you lose or damage a PASS-Key III key, see your dealer or a locksmith who can service PASS-Key III to have a new key made. In an emergency, call Pontiac Roadside Assistance. See "Roadside Assistance" in the Index for more information. 2-41
