Smart Unlock
WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. 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 (only), and the key is in the ignition lock cylinder with one of the front doors open, the SJB commands the doors to unlock.
The vehicle can still be locked with the ignition key in the ignition cylinder by locking the doors with the push button rods, the door lock cylinder or an RKE command from an integrated key or the keyless entry keypad.
