The remote keyless entry system allows for the use of as many as 4 transmitters for each vehicle. Replacement remote keyless entry system transmitters must be first programmed to the specific vehicle using the scan tool.

This process is completed using serial data communication between the scan tool and the remote keyless entry control unit and is the only method available for programming transmitters.

Important: All transmitters for a specific vehicle must be programmed at same time.

Important: Once the programming function of the remote keyless entry system is activated, any transmitter, existing or new, that is not programmed, or reprogrammed, during the programming procedure will no longer operate the remote keyless entry system of that vehicle.

Important: Make sure that the doors, hood and trunk/rear hatch are closed before beginning the programming procedure.

1. Connect the scan tool to the data link connector (DLC).
2. Turn the scan tool ON by pressing the power button. Wait for the MAIN MENU screen to be displayed.
3. From the MAIN MENU screen, select diagnostics by pressing the number 1 on the key pad.
4. From the MODEL YEAR screen, select the appropriate model year of the vehicle by either scrolling down to the year and pressing ENTER, or by pressing the respective item number on the key pad.
5. From the VEHICLE TYPE screen, select the specific vehicle model by either scrolling down to the model name and pressing ENTER, or by pressing the respective item number on the key pad.
6. From the SYSTEM SELECTION MENU screen, select body by pressing the number 2 on the key pad.
7. From the BODY SELECTION MENU screen, select coding by pressing the number 2 on the key pad.
8. From the CODE SELECTION MENU screen, select coding by pressing the number 1 on the key pad.
9. From the SECRET NUMBER OF CODINGS screen, enter 4 zeros in the 4 boxes labeled 1-2-3-4-.
10. From the CODING SYSTEM SELECT screen, select keyless entry by pressing the number 2 on the key pad.

Important: A slight delay may occur and PLEASE WAIT may be displayed before the next screen appears.

11. From the KEYLESS ENTRY CODING SYSTEM screen, select coding transmitter by pressing the number 1 on the key pad.
12. When directed by the scan tool, press any button on the first transmitter to be programmed.

Important: Ensure that transmitters from other vehicles in the immediate area are not activated during this procedure.

13. Continue programming transmitters when directed by the scan tool until all transmitters have been programmed.

Important: A maximum of 4 transmitters may be programmed to a vehicle.

14. Once all transmitters have been programmed, press the ESC button on the key pad. The display will confirm the number of transmitters programmed. If the number displayed does not match the number of transmitters programmed, repeat the procedure.
15. Turn the scan tool OFF by pressing the power button, then disconnect it from the DLC.
16. Wait approximately 10 seconds, then test the operation of each programmed transmitter to ensure it operates properly.

The control module/receiver leaves the programming mode automatically and switches to the normal operating mode when either of the following conditions occur:
