The RKE transmitters 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 smart junction box (SJB) every time an RKE button is pressed.
All RKE transmitters must be present to begin diagnosis of the RKE system.
