GM Service Manual Online
For 1990-2009 cars only

This vehicle has a content theft-deterrent alarm system.

To activate the theft-deterrent system, do one of the following:

    • Press on the Remote Keyless Entry (RKE) transmitter or the power door lock switch when any door is open.

Object Number: 811473  Size: A1

The security light flashes.

    • When the door is closed, the security light stops flashing and stays on solid for approximately 30 seconds. The content theft deterrent alarm is not armed until the security light goes off.
        If the delayed locking feature is active, the alarm is not activated until all doors are closed and the security light goes off.
    • Press when the driver door is closed. The security light comes on solid for approximately 30 seconds and then goes off. The content theft deterrent alarm is not armed until the security light goes off.

The theft-deterrent system will not activate if the doors are locked with the vehicle's key or the manual door lock.

If a locked door is opened without using the key in the driver door key cylinder or the RKE transmitter, a ten second pre-alarm occurs. The horn chirps and the lights flash. If the key is not placed in the ignition and turned to START or the door is not unlocked by pressing during the ten second pre-alarm, the alarm goes off. The headlamps flash and the horn sounds for about two minutes, then turns off to save the battery power.

The vehicle can be started with the correct ignition key if the alarm has been set off.

To avoid setting off the alarm by accident:

    • Lock the vehicle with the door key after the doors are closed.
    • Unlock the door with the RKE transmitter. Unlocking a door any other way sets off the alarm if the system has been armed.

Press or place the key in the ignition and turn it to START to turn off the alarm.

Testing the Alarm

  1. From inside the vehicle, lower the driver side window and open the driver door.

  3. Get out of the vehicle, close the door and wait for the security light to go out.

If the alarm does not sound when it should, but the vehicle's headlamps flash, check to see if the horn works. The horn fuse may be blown. To replace the fuse, see Fuses and Circuit Breakers .
