Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Depending on the car's maker and model, the procedure could be as simple as onboard programming with a spare working key or as complex as OBD2 or EEPROM programming.
Most US and Asian automakers share their programming protocol with auto tool manufacturers, so they can design software or hardware for automotive locksmiths.
Transponder Chips
Most newer cars use what are called transponder chips to stop car theft. These are small computer microchips which emit radio signals of low-level. The microchips are equipped with a unique serial number which authenticates your keys when you plug it into the ignition barrel. If your car isn't able to recognize the signal it will stop the engine. This technology has proven to be an enormous success in preventing car theft.
