Remote Keyless Entry (RKE)

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

The SJB interprets radio frequency signals from the Remote Keyless Entry (RKE) transmitters. The SJB requests the illuminated entry feature to turn the interior lamps on when an unlock command is received. If a lock command is received, the illuminated entry feature turns off.

The RKE transmitter supplies a signal to the SJB when any button is pressed. The SJB then supplies voltage to the appropriate door lock actuator(s) to lock or unlock the doors. The RKE transmitter can also be used to release the luggage compartment lid or activate the panic alarm. On MKZ, the RKE transmitter also causes the SJB to send an MS-CAN message to the Driver Seat Module (DSM) to activate all memory features to the positions associated with the RKE transmitter being used.
