Normal Operation

WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The RKE transmitters and the smart junction box (SJB) use a rolling code to prevent the codes from being captured by a code grabber. The system advances the counter in the RKE transmitter and in the SJB every time a RKE transmitter button is pressed.

All RKE transmitters must be present to begin diagnosis of the RKE system.
