Power Unlock Inhibit
WARNING: This page is about a different car, the 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, 2003 Ford Excursion, and 2003 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
With the ignition off, 20 seconds after electrically locked (keyless entry remote transmitter, keypad, door lock control switch locked with door ajar) and all doors are closed, the power door unlock switch will be disabled if this feature is enabled. (The lock function will still operate.)
