Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the model and make the process could be as simple as using an additional key to programme the computer onboard, or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian automobile manufacturers use the same programming protocols as auto tool makers to allow them to develop tools and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are used in a lot of modern cars to prevent car theft. These are tiny computer microchips that emit low-level radio signals. The microchips have a unique serial number which authenticates your key whenever you connect it to the ignition barrel. If your vehicle isn't able to recognize the signal and the engine is shut down.
