Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the car's maker and model, the procedure can be as simple as onboard programming using a spare working key or as complicated as EEPROM or OBD2 programming.
Most US and Asian car manufacturers use the same programming protocols as auto tool manufacturers to allow them to develop hardware and software for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are used in many newer cars to stop theft of cars. These are tiny computer microchips which emit low-level radio waves. They have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle isn't able to recognize the signal, the engine will be shut down. This technology has proven to be an enormous success in preventing auto theft.
