Integrated Keyhead Transmitter (IKT)
WARNING: This page is about a different car, the 2014 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The RKE system uses an IKT . The IKT incorporates both the PATS and RKE functions into a single device. The factory installed remote start (if equipped), is controlled by the IKT function and allows the engine to be started from outside the vehicle. The RKE functions controls the door lock/unlock features.
