Power Unlock Inhibit
WARNING: This page is about a different car, the 2002 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
With the key OFF, 20 seconds after electrically locked (key fob, keypad, door lock control switch locked with door ajar) and all doors are closed, the power door unlock switch will be inhibited if this feature is enabled. (The lock function will still operate.)
