The keyless entry system is a supplementary vehicle entry device. Radio frequencies
or discharged batteries may disable the system.
Keyless entry allows you to operate the following components:
| • | The door locks, including the rear compartment |
| • | The illuminated entry lamps |
The keyless entry system has the following main components:
| • | The radio antenna module |
When you press a button on a transmitter, the transmitter sends a RF signal
to the radio antenna module. The module interprets the signal and activates the requested
function via a class 2 message over the serial data line.

instructions, refer to
Driver Personalization
in
Personalization.
Rolling Code
The Keyless Entry 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 the keyless entry system sends and receives the signals. The transmitter
sends the signal in a different order each time. The transmitter and the radio antenna
module are synchronized to the appropriate order. If a programmed transmitter sends
a signal that is not in the order that the radio antenna module expects, then the
transmitter is out of synchronization. This occurs after 256 presses of any transmitter
button when it is out of range of the vehicle.
Automatic Synchronization
The keyless entry transmitters do not require a manual synchronization procedure.
If needed, the transmitters automatically resynchronize when any button on the transmitter
is pressed within range of the vehicle. the transmitter will operate normally after
the automatic synchronization.
