Handles, Locks, Latches and Entry Systems - With Intelligent Access (IA): Overview
WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The power lock/unlock feature locks or unlocks the doors upon a customer request from either door lock control switch in the vehicle, RKE transmitter, or keyless entry keypad. The power door locking system functions independently of ignition status or vehicle speed.
The Intelligent Access (IA) feature allows easy locking and unlocking of the vehicle and opening the power liftgate without having to use a key.
