GM Service Manual Online
For 1990-2009 cars only

This feature lets the driver delay the actual locking of the vehicle. When the driver's power door lock switch or the remote keyless entry lock button is pressed, with the key removed from the ignition and the driver's door open, a chime will sound three times to signal that the delayed locking system is active. When all doors have been closed, the doors will lock automatically after five seconds. If any door is opened before this, the five-second timer will reset itself once all the doors have been closed again.

Pressing a power door lock switch or the remote keyless entry lock button again will override this feature.

Personalization Programming

The delayed locking feature can be turned on or off.

If your vehicle is equipped with the Driver Information Center (DIC), you must program this feature through the DIC. See DIC Vehicle Personalization .

If your vehicle is not equipped with remote keyless entry, the delayed locking feature can be turned on or off by using the following procedure:

  2. Press and hold the driver's power door lock switch in LOCK through Step 4.
  3. Cycle the parking lamp switch from off to on six times. On the sixth cycle, the doors will unlock to confirm that the feature has been turned on. Your doors will remain locked if delayed locking is off. If the doors unlock, delayed locking is on.
  4. To change modes, cycle the parking lamp switch once more. A locking action will confirm the new mode.
  5. Release the power door lock switch.

To turn the feature off, repeat the previous procedure.

If your vehicle is equipped with remote keyless entry, your vehicle can be programmed to each driver's preference for each of the transmitters. Use the following procedure to turn the feature off using the corresponding transmitter:
