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 rear compartment lid release |
| • | The illuminated entry lamps |
| • | The panic alarm (instant alarm) |
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 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. The keyless Entry
transmitter has an operating range of 10 Meters (32 Feet) from the vehicle.

Keyless Entry Personalization
The exterior lamps and horn chirp may be personalized for two separate drivers
as part of remote activation verification. For mode descriptions and programming
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 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 the RCDLR 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.
