Transmitter Programming

METHOD 1-NO TOOLS REQUIRED
In the event that a transmitter is lost, program the old and the new transmitters into the memory of the remote control door lock receiver. Up to 4 transmitters may be programmed.

IMPORTANT:
^ Once entering this procedure, programming the first transmitter erases all previous transmitters. You must program all transmitters.
^ Program one vehicle at a time. One transmitter could be programmed into other vehicles that are also on program mode in close proximity.

1. Sit in the driver's seat.
2. Remove the ignition key from the ignition lock cylinder.
3. Close all vehicle doors.
4. Press and hold unlock on the door lock switch.
5. While holding the door lock switch in the unlock position, insert and remove the ignition key twice. Do not rotate the ignition lock cylinder.
6. Insert the ignition key a third time leaving the key in the ignition lock cylinder. The ignition must remain in the LOCK position for the rest of the procedure.
7. Release the door lock switch. You will hear three chimes. This chime feedback indicates that transmitter programming is active.
8. Press and hold the lock and unlock buttons at the same time on the keyless entry transmitter for 12 seconds. You will hear two chimes. This chime feedback indicates that the transmitter has been programmed successfully.
9. Repeat step 8 for the rest of the transmitters (for a total of 4 transmitters).
10. Exit this procedure by removing the ignition key from the ignition lock cylinder.

METHOD 2-SCAN TOOL REQUIRED
In the event that a transmitter is lost, program the old and the new transmitters into the memory of the remote control door lock receiver. Up to 4 transmitters may be programmed.

IMPORTANT: Once the keyless entry receiver enters the programming/diagnostic mode, the programming of the first transmitter erases all previous transmitter programming information. You must then program all of the transmitters.

Program only 1 vehicle remote control door lock receiver at a time. If you program multiple receivers simultaneously, the same transmitter may possibly be programmed to more than 1 remote control door lock receiver.

The following procedure describes how to program the remote control door lock transmitters to the remote control door lock receiver using the Tech 2 . You may also use an equivalent scan tool in order to perform this procedure.

Perform the following steps:
1. Connect the scan tool to the following components:
^ An applicable power source
^ The vehicle Data Link Connector (DLC)
2. Turn the ignition ON.
3. At the application menu screen, select F0 (body control module).
4. At the body control module screen, select F2 (special functions).
5. At the special functions menu screen, select F3 (program key fobs).
6. Follow the directions on the scan tool display in order to program the transmitters.
7. Press EXIT repeatedly until you view the application menu screen.
8. Disconnect the scan tool from the following components:
^ The accessory power port
^ The vehicle DLC
9. Validate that all the transmitters that were programmed operate properly. Refer to Remote Keyless Entry System Operation. Description and Operation
