Automotive Locksmith Key Programming Modern automobiles require some kind of key programming. Based on the model and make, the process may be as simple as using a spare key to program the onboard computer or as complex as EEPROM or OBD2 programming. Most US and Asian automobile manufacturers have programming protocols that they share with auto tool makers in order to create hardware and software for automotive locksmiths to use.
