General Description

Remote Lock Control Transmitter (Typical):

The Remote Control Door Lock Receiver System allows the driver to unlock the drivers door, unlock all doors, lock all doors or release the rear compartment lid by the use of a hand held transmitter.

The range of the transmitter is approximately seven meters (23 feet). If the transmitter range becomes less than approximately seven meters (23 feet) the battery in the transmitter 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. Service and Repair

Under some conditions the range of the transmitter may be decreased from normal range or the receiver may not operate due to interference from anonymous radio signal transmissions. Therefore, the door lock key (oval head) should be attached to the ring on the transmitter so it will be available if needed.

When the drivers door or rear compartment lid is unlocked by using the transmitter the interior lamps are turned 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. Interior lamps are controlled by a switch mounted on the door handle. The Remote Control Door Lock Receiver controls (turns on) the interior lamps when the UNLOCK or REAR COMPARTMENT LID button on the transmitter is pressed.

Serial data is transmitted on a radio frequency carrier signal at 315 MHz from the transmitter to the Remote Control Door Lock Receiver when one of three buttons on the transmitter is pressed. The three buttons are:
^ Lock Doors
^ Unlock Door(s)
^ Rear Compartment Lid Release

The transmitter is resistant to moderate temperature changes, shock, moisture, dust and most common household and automotive fluids.
