Automotive Locksmith Key Programming Modern cars require some type of key programming. Based on the model and manufacturer the procedure could be as simple as using an additional key to program the onboard computer or as complicated as EEPROM or OBD2 programming. Most US and Asian auto manufacturers use the same programming protocols as auto tool makers, which means they can develop tools or hardware for automotive locksmiths. Transponder Chips Transponder chips are used in many newer cars to stop theft of cars. These are tiny computer microchips which emit radio signals of low-level. They have a unique serial number which authenticates your key whenever you insert it into the ignition barrel. If your car doesn't recognise the signal it will stop the engine.
