Why The Biggest "Myths" About Automotive Locksmith Key Programming Could Be True
Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Based on the car's make and model, the process can be as simple as programming onboard using a spare key that works or as complex as OBD2 or EEPROM programming.
