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.
Unlock Driver Door Only
Momentarily press the UNLOCK button in order to perform the following functions:
| • | Unlock the driver door only. |
| • | Illuminate the interior lamps for a predetermined amount of time or until the ignition is turned ON. |

| • | Disarm the content theft deterrent (CTD) system. |
| • | Deactivate the CTD system when in the Alarm Mode. |
| • | Recall the memory seat and memory mirror positions for that driver. |
Unlock All Doors (Second Operation)
Momentarily press the UNLOCK button a second time (within 2 seconds of the first press) in order to perform the following functions:
| • | Unlock the remaining doors. |
| • | Illuminate the interior lamps for a predetermined amount of time or until the ignition is turned ON. |

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 the Owners Manual.
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.
