On-Board programming Modern key fobs do more than unlock the rear hatch and start your car. They contain transponders that communicate with the vehicle via an antenna and transmit data such as an ID code or even the VIN of the vehicle. The vehicle will then be able to unlock doors and start the engine when the key is present. Transponders must also be programmed using the immobilizer codes. Certain vehicles come with an easy procedure, while others require special software and key programming tools. If you're working with a vehicle that has onboard programming, the owner's manual or an Internet search for “onboard programing steps for X car” will provide you with the necessary information. In some cases, the key will require cloning and the new key must have the same immobilizer codes as the one that is currently. This is accomplished by using an instrument designed specifically for key programming that harvests the code from the module and burns it into the new key. Certain vehicles require that the transponder to be completely programmed. This is possible through a J2534 connection however it typically requires removing the module.
