Automotive Locksmith Key Programming Modern cars need some kind of key programming. Depending on your vehicle's model and manufacturer, the process may be as simple as using a spare key to program the onboard computer, or as complicated as OBD2 programming or EEPROM. Most US and Asian automakers share their programming protocol with auto tool makers, so they can design tools or hardware for locksmiths in the automotive industry. Transponder Chips Most newer cars use what are called transponder chips to prevent car theft. These are small computer microchips that emit radio signals at a low level. The microchips are equipped with an unique serial number that authenticates your key when you plug it into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has been an enormous success in preventing auto theft.

These kinds of thefts have drastically decreased with the introduction of the transponder chip.
