The majority of US and Asian automobile manufacturers use the same programming protocols as auto tool makers to allow them to develop tools and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are used in a lot of modern cars to prevent car theft. These are small computer microchips which emit radio signals of low-level. The microchips are equipped with a unique serial number which authenticates your key when you plug it into the ignition barrel.
