The majority of US and Asian automakers have a programming protocol that they share with auto tool manufacturers, so they can develop hardware or software for automotive locksmiths.

Transponder Chips

Transponder chips are found in many newer cars to stop theft of cars. These are tiny computer microchips that emit radio waves at a low level. They are equipped with a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel.
