Lockout Prevention
WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
This function is intended to prevent the vehicle operator from locking the doors if the key is left in the ignition and any vehicle door is open. The body control module (BCM) will react after locking all the doors by unlocking the driver door. The lockout prevention function can be overridden by manually locking the door.
