The keyless entry system is a supplementary vehicle entry device. Radio frequency
interference or discharged batteries may disable the system.
Keyless entry allows you to operate the following components:
| • | The rear compartment lid release (Press and hold rear release button for
greater than 1.5 seconds to activate). |
| • | The illuminated entry lamps |
| • | The panic alarm (instant alarm) |
The keyless entry system has the following main components:
| • | The body control module (BCM) |
| • | The remote control door lock receiver (RCDLR). When you press a button
on the transmitter, the transmitter sends a signal to the RCDLR. The RCDLR receives
the signal and sends a class ll serial data message requesting the appropriate function
from the BCM. |
Unlock Driver's Door Only
Momentarily press the UNLOCK button in order to perform the following functions:
| • | Unlock the driver door only. |
| • | Illuminate the interior lamps for approximately 10 seconds or
until the ignition is turned ON. |
| • | Flash the park lamps twice if the ignition is turned OFF and the doors
are closed. |
Unlock All Doors - Second Operation
Momentarily press the UNLOCK button a second time, within 5 seconds
of the first press, in order to perform the following functions:
| • | Unlock all of the doors. |
| • | Illuminate the interior lamps for approximately 10 seconds or
until the ignition is turned ON. |
Lock All Doors
Press the LOCK button in order to perform the following functions:
| • | Immediately turn OFF the interior lamps. |
| • | Flash the park lamps twice if the ignition is OFF and the doors are closed. |
| • | Chirp the horn if the ignition is OFF and the doors are closed. |
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 body control module (BCM) or 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 BCM or the RCDLR expects, the system will not function.
This occurs after 256 presses of any button on the transmitter when it is out of range
of the vehicle.
