Automotive Locksmith Key Programming Most modern-day cars require some form of key programming. Depending on the vehicle's make and model, the procedure can be as easy as onboard programming with a spare key that works or as complex as EEPROM or OBD2 programming.

Transponder Chips Transponder chips are found in many newer cars to guard against theft of vehicles. These are tiny computer microchips that emit radio waves of low-level. The microchips are equipped with an unique serial number that authenticates your key when you plug it into 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 in the key.
