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
- The rear compartment lid release
- The illuminated entry lamps
- The panic alarm/instant alarm
The keyless entry system has the following main components:
- The transmitters
- The endgate module (EGM) (XUV only)
- The liftgate module (LGM) (Except XUV)
When you press a button on a transmitter, the transmitter sends a signal to the liftgate module. The module interprets the signal and activates the requested function via a class 2 message over the serial data line.
