Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Based on the car's make and model, the procedure can be as easy as onboard programming using a spare key that works or as complex as OBD2 or EEPROM programming.
Most US and Asian auto manufacturers share their programming protocol with auto tool makers, which means they can develop tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are used in a variety of newer vehicles to prevent car theft. These are tiny computer microchips that emit radio waves at a low level. They have an unique serial number that authenticates your keys when you insert it into the ignition barrel. If your vehicle isn't able to recognize the signal and the engine is shut down.
