Automotive Locksmith Key Programming Modern cars require some type of key programming. Based on the car's make and model, the process can be as easy as onboard programming with an extra working key or as complicated as OBD2 or EEPROM programming. The majority of US and Asian automakers use the same programming protocols as auto tool manufacturers, so they can develop software or hardware for locksmiths in the automotive industry. Transponder Chips Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are tiny computer microchips which emit radio waves of low-level. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has been an enormous success in preventing theft of cars.
