The keyless entry system is a vehicle entry device. The keyless entry system is used in conjunction with the door locks to lock and unlock the vehicle. Keyless entry will lock/unlock the doors when a corresponding button on the keyless entry transmitter is pressed. This is accomplished by the transmitter sending a radio frequency to the liftgate module (LGM). The LGM interprets the signal and activates the requested function via a serial data message to the body control module (BCM). A low transmitter or vehicle battery or radio frequency (RF) interference from aftermarket devices, such as 2-way radios, power inverters, computers, etc., may cause a system malfunction. High RF traffic areas may also cause interference that could lead to a malfunction. Keyless entry allows you to operate the following components:

The keyless entry system has the following components:

The keyless entry transmitters are used to lock and unlock the vehicle door while away from a distance of up to 9 m (30 feet) away. Up to 4 transmitters may be programmed to a single vehicle.

The liftgate module (LGM) is a multifunction module that operates both the keyless entry system as well as the TPM system. When an RF message is received from a keyless entry transmitter, the LGM interprets this signal and will request via serial data that the body control module (BCM) perform the specific function, i.e. door lock, door unlock, or vehicle locate.

Momentarily press the transmitter UNLOCK button in order to perform the following functions:

Momentarily press the transmitter UNLOCK button a second time, within 5 seconds of the first press, to perform the following function:

Unlock the remaining doors and the liftgate.

Press the transmitter LOCK button to perform the following functions:

A press and hold of the panic button performs the following functions:

Vehicle lock/unlock functions may be personalized. For functional descriptions and programming instructions, refer to the vehicle Owner's Manual.

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 LGM are synchronized to the appropriate order. If a programmed transmitter sends a signal that is not in the order that the LGM 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.

The keyless entry transmitters do not require a manual synchronization procedure. If needed, the transmitters automatically re-synchronize when any button on the transmitter is pressed within range of the vehicle. The transmitter will operate normally after the automatic synchronization.
