Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Depending on the car's maker and model, the process can be as simple as programming onboard using a spare key that works or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian auto manufacturers share their programming protocol with auto tool manufacturers, so they can develop hardware or software for automotive locksmiths.
Transponder Chips
