Remote Control Door Lock Transmitter Programming (Scan 100)

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

The 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 the same time.
