Automotive Locksmith Key ProgrammingModern vehicles require some form of key programming. Based on the model and make, the process may be as simple as using an additional key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.Most US and Asian car manufacturers have programming protocols that they share with auto tool makers in order to create software and hardware for locksmiths in the automotive industry to use.Transponder ChipsMost modern cars are equipped with transponder chips to prevent car theft.

This antenna is programmed so that it can detect the particular frequency of the chip inside the key.
