Automotive Locksmith Key Programming Modern cars need some kind of key programming. Based on the car's make and model, the process can be as simple as onboard programming with an extra working key or as complicated as OBD2 or EEPROM programming. The majority of US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, so they can design tools or hardware for automotive locksmiths. Transponder Chips Transponder chips are used in a variety of newer vehicles to guard against theft of vehicles. These are small computer microchips 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 connected to the ignition barrel.
