Skoda Key Programming The key programming features useful if you run a repair shop for cars. Customers might require a new key fob because their original key fob is missing, or they may need you to duplicate transponder codes on a replaced module.

On-Board programming Modern key fobs go beyond a simple remote control that allows you to start your car, and also open the rear hatch. They contain transponders that communicate with the vehicle through an antenna, and also transfer information like an ID number or even the VIN of the vehicle. This is how the vehicle knows who has the key, and can unlock doors or start the engine. These transponders should also be programmed with immobilizer codes. Certain vehicles can accomplish this with a simple set of steps, while others require special software and key programming tools. If the vehicle you're working on is a vehicle that has onboard programming, you can learn about it in the owner's manual, or by searching the Internet for “onboard programming steps for X car.” In some cases, the key will require cloning in order to make it appear as if the new key must be equipped with the same immobilizer codes as the existing one. This is done through a specialized key programming tool that extracts the code from the module and then burns it into the new key. Certain vehicles require that the transponder to be completely reprogrammed. This is possible with a J2534 connection however, it usually requires removing the module.
