Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Depending on the car's maker and model, the process can be as simple as onboard programming with an extra working key or as complex as EEPROM or OBD2 programming.
Most US and Asian automakers have a programming protocol that they share with auto tool makers, which means they can develop hardware or software for automotive locksmiths.
Transponder Chips
The majority of newer cars have what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit radio waves at a low level. The microchips are equipped with a unique serial number that authenticates your key whenever you connect it to the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has been an immense success in stopping auto theft.
