Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the model and manufacturer, the process may be as simple as using a spare key to program the onboard computer, or as complex as OBD2 programming or EEPROM.
Most US and Asian automobile manufacturers have programming protocols that they share with auto tool makers in order to create software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are in many newer cars to guard against theft of vehicles. These are tiny computer microchips that emit radio signals at a low level. They are equipped with a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel.
