WARNING: This page is about a different car, the 2002 Buick LeSabre. However, it is still accessible from the selected car via links, so may be relevant.
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.

When you press a button on a transmitter, the transmitter sends a signal to the remote control door lock receiver. The RCDLR interprets the signal and activates the requested function via a class 2 message over the serial data line.
