Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Based on the car's make and model, the procedure could be as simple as programming onboard using an extra working key or as complicated as OBD2 or EEPROM programming.
Most US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, which means they can develop hardware or software for locksmiths in the automotive industry.
reprogram car key are equipped with transponder chips in order to prevent theft. These are tiny computer microchips which emit radio waves of low-level. The microchips have an unique serial number that authenticates your keys when you connect it to the ignition barrel. If your car doesn't recognise the signal, it will shut down the engine.

The antenna is programmed to match the frequency of the chip within the key.
