Automotive Locksmith Key Programming

Modern vehicles require some form of key programming. Depending on how to program a car key and model, the process can be as easy as programming onboard using a spare key that works or as complicated as OBD2 or EEPROM programming.

Transponder Chips

Most modern cars are equipped with what are called transponder chips to prevent car theft. These are small computer microchips that emit low-level radio signals.
