Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Depending on the car's maker and model, the procedure can be as simple as programming onboard using a spare key that works or as complicated as EEPROM or OBD2 programming.

Transponder Chips
The majority of newer cars have what are called transponder chips to stop car theft. These are tiny computer microchips that emit low-level radio signals. The microchips have a unique serial number which authenticates your keys when you connect it to the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has been extremely successful in preventing car theft. It also saves many car owners a significant amount of money because they don't have to replace their vehicles.

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