On-Board programming Modern key fobs do more than just unlock the rear hatch and get your car started. Transponders connect to the vehicle via an antenna, and send data like an ID number or VIN. This is how the vehicle can identify who is the owner of the key and can unlock doors and start the engine. These transponders must also be programmed with immobilizer codes. Some vehicles can be programmed by following a straightforward sequence of steps, while others require specialized software and key programming tools. If the car you're working on is one that has onboard programming, you can find out about it in the owner's manual or by searching the Internet for “onboard programming steps for X car.” In some cases keys will need to be cloned, which means that the new key must be equipped with the same immobilizer codes as the one that is currently. This is accomplished by using a specialized key programming tool that harvests the code from the module and burns it onto the new key.
