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 features:

• | The panic alarm.

The keyless entry system has the following main components:

• | The transmitters.

• | The remote function actuator (RFA) module -- When you press a button on the transmitter, the transmitter sends a signal to the RFA module. The RFA module receives the signal and sends a GMLAN serial data message requesting the appropriate function.

### Unlock Driver Door Only
