2002 Cadillac DeVille Owner's Manual - Page 89

This device complies with RSS-210 of Industry Canada. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference received, including interference that may cause undesired operation of the device. Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment. PASS-Key III uses a radio frequency transponder in the key that matches a decoder in your vehicle. When the PASS-Key III system senses that someone is using the wrong key, it shuts down the vehicle's starter and fuel systems. The starter will not work and fuel will stop being delivered to the engine. Anyone using a trial-and-error method to start the vehicle will be discouraged because of the high number of electrical key codes. When trying to start the vehicle, if the engine does not start and the SECURITY light comes on, the key may have a damaged transponder. Turn the ignition off and try again. If the engine 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" in the Index. 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 who can service the PASS-Key III to have a new key made. 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. Canadian Owners: If you lose or damage your keys, only a GM dealer can service PASS-Key III to have new keys made. To program additional keys you will require two current driver's keys (black in color). You must add a step to the following procedure. After Step 2, repeat Steps 1 and 2 with the second current 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 current driver's key in the ignition and start the engine. If the engine will not start see your dealer for service. 2-21
