Automotive Locksmith Key Programming Modern vehicles require some form 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 OBD2 programming or EEPROM. Most US and Asian automakers share their programming protocol with auto tool makers, which means they can design software or hardware for automotive locksmiths. Transponder Chips Transponder chips are in a variety of newer vehicles to guard against theft of vehicles. These are tiny computer microchips which emit radio waves of low-level. They have 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.
