GM Service Manual Online
For 1990-2009 cars only

To activate the theft-deterrent system:

  1. Open the door.
  2. Lock the door with the power door lock switch or the Remote Keyless Entry (RKE) transmitter. If you are using the RKE transmitter, the door does not need to be open.
  3. Locking the driver's door with the key will not activate the theft deterrent system.

  4. Close all doors.

If the theft-deterrent system is activated and a door or the liftgate is opened without using the RKE transmitter, a 10 second pre-alarm will occur, and the security light will flash. The horn will sound rapidly for 10 seconds. If you do not press unlock on the RKE transmitter or insert the key in the ignition and turn if from the LOCK/OFF position, the alarm will go off. The horn will sound and the headlamps will flash for 30 seconds.

After the alarm has sounded for 30 seconds, the system will re-arm itself automatically.

Arming with the Power Lock Switch

The alarm system will arm when you use either power lock switch to lock the doors while any door is open and the key is removed from the ignition.

Arming with the RKE Transmitter

The alarm system will arm when you use your RKE transmitter to lock the doors, if the key is not in the ignition.

Disarming with the RKE Transmitter

The alarm system will disarm when you use your RKE transmitter to unlock the doors.

Disarming with Your Key

The alarm system will disarm when you use your key to unlock the doors and insert your key in the ignition and turn it from the LOCK position.

Unlocking the driver's door with the key will not disarm the theft deterrent system.
