Rolling Code

The Remote Keyless Entry (RKE) system uses rolling code technology. Rolling code technology prevents anyone from recording the message sent from the transmitter and using the message in order to gain entry to the vehicle. The term "rolling code" refers to the way that RKE system sends and receives signals. The transmitter sends signals in a different order each time. Transmitters and Remote Control Door Lock Receiver (RCDLR) are synchronized to the appropriate order. If a programmed transmitter sends a signal that is not in the order that RCDLR expects, then transmitter is out of synchronization. This occurs after 256 presses of any transmitter button when it is out of vehicle range.

Transmitter may also go out of synchronization if battery in transmitter is very weak, battery in transmitter has been replaced or vehicle battery has been in a low or no charge condition for an extended period of time. To resynchronize transmitters, see TRANSMITTER RESYNCHRONIZATION  under PROGRAMMING.
