Automotive Locksmith Key Programming
Modern cars need some form of key programming. Based on source web page 's make and model, the procedure can be as simple as onboard programming with a spare key that works or as complicated as OBD2 or EEPROM programming.

Transponder Chips
The majority of newer cars have what are called transponder chips to stop car theft. These are small computer microchips that emit low-level radio signals. 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 doesn't recognize the signal it will shut down the engine. This technology has been an incredible success in preventing auto theft. It also saves many car owners a lot of money as they don't need to replace their vehicles.

Certain key fobs come with pseudo-random code generators that generate a new unlock code each time you press the button.
