The remote keyless entry (RKE) system allows operation of the door locks and
interior lighting from outside the vehicle. Radio frequencies or discharged batteries
may disable the system.
Keyless entry allows you to operate the following components:
| • | The illuminated entry lamps |
| • | The panic alarm (instant alarm) |
The keyless entry system has the following main components:
| • | The body control module (BCM) |
When you press a button on a transmitter, the transmitter sends a signal to
the BCM. The BCM interprets the signal and activates the requested function.
Unlock Driver's Door Only

| • | Chirp the horn twice (if selected ON in personalization). |
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:

| • | Sound the chime 3 times if any door is open when the lock button is pressed
(delayed locking). |

A single press of the panic button performs the following functions:
| • | Illuminate the interior lamps. |
| • | All will occur for a predetermined period of time or until any of the
following conditions occur: |
| - | The panic button is pressed again. |
| - | The ignition switch is turned to the RUN position with a valid key. |
| - | The vehicle is unlocked with the key. |
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) are synchronized to the appropriate order. If
a programmed transmitter sends a signal that is not in the order that the BCM
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.
