Remote Keyless Entry System: Description

CAUTION: When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES -- GENERAL MOTORS article in GENERAL INFORMATION before disconnecting battery.

The Remote Keyless Entry (RKE) system is used to lock and unlock the doors and release the luggage compartment lid of the vehicle. A small receiver is installed to the foundation of the rear compartment panel. The remote transmitter is a hand held item that is attached to a key ring. The transmitter has 3 buttons that control the functions of the remote keyless entry system.

The remote door lock receiver (keyless entry module) is battery fed and is always monitoring the transmitter signal. When the correct transmitter signal is received to lock all of the doors, a transistor driver will energize the correct lock control relay coil. The receiver will also control which lock control relays will be energized to unlock the driver's door or all of the doors.

The transmitter will transmit a radio signal to the receiver, which will control the 3 functions of the remote door lock receiver. The range is approximately up to 10 meters (33 feet).
