Automotive Locksmith Key Programming

The majority of modern cars require some form of key programming. Based on the model and make, the process may be as simple as using an additional key to program the onboard computer or as complicated as EEPROM or OBD2 programming.

The majority of US and Asian automakers have a programming protocol that they share with auto tool makers, so they can develop tools or hardware for locksmiths in the automotive industry.

Transponder Chips

Transponder chips are found in a lot of modern cars to prevent car theft. These are tiny computer microchips which emit radio waves of low-level.
