Automotive Locksmith Key Programming Modern automobiles require some kind of key programming. Based on the model and manufacturer, the process may be as simple as using a spare key to program the onboard computer, or as complicated as OBD2 programming or EEPROM. Most US and Asian automakers have a programming protocol that they share with auto tool makers, so they can develop hardware or software for locksmiths in the automotive industry. Transponder Chips Most newer cars use what are called transponder chips to prevent car theft. These are microchips in the form of computers which emit radio signals 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.
