Automotive Locksmith Key Programming Most modern-day cars require some type of key programming. Depending on the vehicle's make and model, the procedure could be as simple as programming onboard using a spare key that works or as complicated as OBD2 or EEPROM programming. Most US and Asian automakers share their programming protocol with auto tool manufacturers, so they can create hardware or software for automotive locksmiths. Transponder Chips Most modern cars are equipped with what are called transponder chips to stop car theft. These are small computer microchips that emit radio signals at a low level. They have a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel.
