It is possible for the PASS-Key® III decoder to accept the transponder value of a new or replacement key. Up to 10 keys may be programmed for the vehicle. If all the programmed keys are lost or do not operate, see your GM dealer or a locksmith who can service PASS-Key® III to have keys made and programmed to the system. Canadian Owners: If all the keys are lost or damaged, only a GM dealer can service PASS-Key® III to have new keys made and programmed to the system. The following procedure is for programming a new or replacement key when you have at least one already programmed key. 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 STARTING 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 SERVICE 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 STARTING 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. 104
