Last Door Closed Locking and Lockout Prevention

Last door closed locking is available on cars with power locks, this feature provides for delayed locking of the door (three seconds after the last door is closed). This allows the driver to exit the vehicle and press the lock button (either on the key fob or the door panel), but the doors will not lock until both doors are closed. When the locked switch is pressed, the chime will sound three times, indicating a last door closed locking is pending. Pressing the lock switch again will lock the doors immediately. Pressing the unlock switch will cancel a pending last door closed locking. Last door closed locking is disabled from the factory, and can be enabled if desired.

Lockout prevention protects the driver from locking the keys in the vehicle, this feature disables the power lock from locking when the keys are in the ignition and a door is open. If the power lock button is pressed when a door is open, the chime will sound 5 times as a reminder to take the keys before locking the door. Lockout prevention is enabled from the factory, and can be disabled if desired.

  2. Press the lock switch on the door.
  3. Listen to the number of chimes to determine current setting.
