Keyless Entry Module

All keyless entry modules (receivers) may be programmed to receive two vehicle access codes (VAC). That is, two different transmitters may be used to operate the remote control lock system on the vehicle. Also, several vehicles, each with the remote lock control may all be programmed to operate from the same transmitter or two different transmitters. During the programming of the keyless entry module, feedback is provided by the receiver by cycling the door locks. To program a keyless entry module (receiver) to match the VAC of one or two transmitters:

1. Jumper keyless entry modules "program" connector, with a jumper between the two cavities. The program connector is located forward of the left rear inner wheel panel, inside the luggage compartment. See Fig 1 . The program connector contains two cavities, A and B. See Fig 2 . The Tan wire in cavity A is the programming lead, and the Black wire in cavity B is a ground. Jumping cavity A to B will initiate the program mode. The module will cycle the door locks as an indication of program mode feedback.

2. Press one button on the transmitter one time to store that transmitters VAC. The door locks will cycle as feedback.
NOTE: If only one transmitter will be used, go to next step.
3. Press one button on the second transmitter, to store the second transmitters VAC. (The first transmitters VAC is retained.) The door locks will cycle as feed back. If a second VAC signal is not received before the programming harness is removed, the receiver will be programmed to the first transmitters VAC only. This procedure deters unauthorized programming without owner knowledge.
4. Remove programming (jumper) harness to restore normal system operation.
5. Verify proper operation of remote lock control system.
