System Description

The Remote Control Door Lock Receiver System allows the driver to perform the following functions by use of a handheld transmitter:
^ Unlock the drivers door (5)
^ Lock all of the doors (3)
^ Release the rear compartment lid The range of the transmitter is approximately seven meters (23 ft). If the transmitter range becomes less than seven meters (23 ft), the battery may need replacing. Refer to Transmitter Battery Replacement. The maximum range of the transmitter is dependent upon ambient conditions as well as other operating parameters.

The following conditions may occur due to interference from anonymous radio signal transmissions:
^ The range of the transmitter may decrease from the normal range
^ The receiver may not operate

Attach the door lock key (oval head) to the ring on the transmitter if needed.

When the drivers door or rear compartment lid is unlocked by using the transmitter, the interior lamps turn on and remain on for approximately forty seconds or until the ignition switch is turned to the RUN position.

This GM vehicle does not have door ajar switches. A switch that is mounted on the door handle controls the Interior lamps. The Remote Control Door Lock Receiver controls the interior lamps when the unlock or rear compartment lid button on the transmitter is pressed.

The serial data transmits on a radio frequency carrier signal at 315 MHz from the transmitter to the Remote Control Door Lock Receiver, when you press one of the following three buttons on the transmitter:
^ Lock Doors
^ Unlock Door(s)
^ Rear Compartment Lid Release

The transmitter is resistant to the following conditions:
^ Moderate temperature changes
^ Shock
^ Moisture
^ Dust
