Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Depending on the vehicle's make and model, the procedure could be as simple as programming onboard using an extra working key or as complex as EEPROM or OBD2 programming.
Most US and Asian automobile manufacturers have programming protocols that they share with auto tool makers to allow them to develop hardware and software for locksmiths in the automotive industry to use.
Transponder Chips
Most modern cars are equipped with transponder chips to stop car theft. These are small 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 vehicle doesn't recognize the signal it will shut down the engine.

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