Smart Unlock
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The smart unlock feature prevents the doors from locking with the key in the ignition lock cylinder. When the SJB 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 SJB commands all the doors to unlock.
