^ The panic mode

The keyless entry system has the following main components:
^ The transmitters
^ The remote function actuator (RFA) module

Rolling Code
The RFA system uses a 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 the RFA system sends and receives the signals. The transmitter sends the signal in a different order each time. The transmitter and the receiver are synchronized to the appropriate order. When the transmitter sends a signal that is not in the order that the receiver expects only the panic mode will function.
