Automotive Locksmith Key Programming Modern cars need some type of key programming. Depending on the model and manufacturer, the process may be as simple as using an extra key to program the onboard computer or as complicated as EEPROM or OBD2 programming. Most US and Asian automakers share their programming protocol with auto tool makers, which means they can develop tools or hardware for automotive locksmiths. Transponder Chips Most newer cars use transponder chips to stop car theft. These are tiny computer microchips that emit radio waves of low-level. The microchips are equipped with a unique serial number which authenticates your key when you connect it to the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has proven to be extremely successful in preventing car theft.
