Smart Unlocking

WARNING: This page is about a different car, the 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The smart unlocking feature prevents the driver door from locking with the key in the ignition. When the vehicle security module receives a LOCK command from a door lock control switch, and the key is in the ignition with the driver door open, the vehicle security module commands the driver door to unlock. The doors can be locked with the key in the ignition using either the RKE keypad or the RKE transmitter.
