Automotive Locksmith Key Programming Modern cars need some form of key programming. Based on the model and manufacturer the process could be as simple as using an extra key to programme the computer onboard, or as complicated as EEPROM or OBD2 programming. Most US and Asian automakers share their programming protocol with auto tool makers, which means they can develop hardware or software for automotive locksmiths.
