Lockout Prevention
WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
The lockout prevention feature prevents the locking of the driver door if the ignition key is left in the ignition lock cylinder. If a lock command occurs from any door lock switch and the BCM detects an active state on either the left front door latch signal, secondary door latch switch signal and/or the liftgate ajar switch signal circuits and the key in ignition switch signal circuit is in the YES state, the BCM, driver door lock/window switch and passenger door lock/window switch will lock the doors and then driver door lock/window switch will unlock the driver door.
