The 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.

When trying to start the vehicle, if the engine does not start and the STARTING DISABLED DUE TO THEFT SYSTEM warning message on the Driver Information Center (DIC) comes on, the key may have a damaged transponder. 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. At this time, you may also want to check the fuse. See Fuses and Circuit Breakers . 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 Pontiac Roadside Assistance. See Roadside Assistance Program for more information.

It is possible for the PASS-Key® III decoder to accept the transponder value of a new or replacement key. Up to 10 additional keys may be programmed for the vehicle. The following procedure is for programming additional keys only. If all the programmed keys are lost or do not operate, see your dealer or a locksmith who can service PASS-Key® III to have keys made and programmed to the system.

If the keys are lost or damaged, only a GM dealer can service PASS-Key® III to have new keys made. To program additional keys, two driver's keys are needed.

Canadian Owners: A step must be added to the following procedure. After Step 2, repeat Steps 1 and 2 with the second driver's key. Then continue with Step 3.

To program the new key do the following:

  1. Verify that the new key has PK3 stamped on it.
  2. Insert the master 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 five seconds of removing the original key.
  5. The SECURITY DISABLED DUE TO THEFT SYSTEM warning message on the DIC will turn off, once the key has been programmed. It may not be apparent that the SECURITY DISABLED DUE TO THEFT SYSTEM warning message went on due to how quickly the key is programmed.
  6. Repeat Steps 1 through 5 if additional keys are to be programmed.

If the SECURITY DISABLED DUE TO THEFT SYSTEM warning message appears and stays on the DIC while the vehicle is being driven, the engine will be able to be restarted if it is turned off. Your PASS-Key® III system, however, is not working properly and must be serviced by your dealer. The vehicle is not protected by the PASS-Key® III system at this time.

If the PASS-Key® III key is lost or stolen, see your dealer or a locksmith who can service PASS-Key® III to have a new key made.
