Smart Unlock

The smart unlock feature prevents the doors from electronically locking with the key in the ignition lock cylinder. When the BCM  receives a lock command from a door lock control switch, and the key is in the ignition lock cylinder with one of the front doors open, the BCM  commands the doors to unlock. To override the smart unlock feature and intentionally lock the doors with the key in the ignition, close all doors and lock the vehicle using the keyless entry keypad or pressing the lock button on an IKT  , or lock the doors manually with the lock rod before closing the door.
