Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Depending on the vehicle's make and model, the procedure could be as simple as programming onboard using a spare key that works or as complex as OBD2 or EEPROM programming.
The majority of US and Asian car makers share their programming protocols with auto tool makers to allow them to develop tools and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Transponder chips are used in a lot of modern cars to guard against theft of vehicles. These are tiny computer microchips that emit low-level radio signals.
