GM Service Manual Online
For 1990-2009 cars only

This vehicle has a passive theft-deterrent system.

You do not have to manually arm or disarm the system.

The system is automatically armed when the key is removed from the ignition.


Object Number: 2010518  Size: G1

The security light, located on the center of the instrument panel, comes on if there is a problem with arming or disarming the theft-deterrent system.

The security light flashes when the system is armed.

When the key is inserted in the ignition the transponder in the key head transmits an electronic code to the vehicle and automatically cancels the system. Only the correct key starts the vehicle.

If the engine does not start, there could be a problem with the theft-deterrent system. 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. 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/retailer who can service the theft-deterrent system and have a new key made.

If any of the following conditions occur, contact your dealer/retailer.

    • The security light stays on.
    • The security light does not start flashing when the key is removed from the ignition.
    • The security light flashes inconsistently.

See your dealer/retailer to have a new key with a transponder made. Bring the key and key number with you.

In an emergency, contact Roadside Assistance Program. See Roadside Assistance Program .

Do not leave the key or device that disarms or deactivates the theft deterrent system in the vehicle.
