### Remote Keyless Entry Transmitter Programming

The remote keyless entry system allows for the use of as many as five (5) transmitters for each vehicle. Replacement remote keyless entry system transmitters must first be programmed to specific vehicle using the Secan 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.

All transmitters for a specific vehicle must be programmed at same time. 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. Ensure that the doors, hood and trunk/tailgate hatch are closed prior to starting the programming procedure.

Ensure that transmitters from other vehicles in the immediate area are not activated during programming procedure. Turn the ignition to ON before installing in the scan tool. Failure to connect in this procedure may cause communication errors and the programming procedure will not complete.

Any keys that are not programmed at this time will no longer function.

1. Turn ON the ignition, with the engine OFF.
2. Install the scan tool.
3. Select PROGRAMMING KEY FOBS from the BODY menu.
4. Follow the scan tool instruction with each key until all keys are programmed.
5. Turn the ignition to the LOCK position, disconnect the Tech 2 and test all the keys.
