Automotive Locksmith Key Programming The majority of modern cars require some form of key programming. Depending on the vehicle's make and model, the process can be as simple as programming onboard using a spare working key or as complicated as OBD2 or EEPROM programming. The majority of US and Asian car manufacturers share their programming protocols with auto tool manufacturers to allow them to develop tools and hardware for locksmiths working in automotive vehicles. Transponder Chips Most modern cars are equipped with transponder chips to prevent car theft. These are tiny computer microchips which emit radio waves of low-level. They have a unique serial number that authenticates the key to your vehicle when it is connected to the ignition barrel.

This antenna is programmed to detect the particular frequency of the chip within the key.

Locksmiths can program keys quickly by using onboard programming. It takes as little as a minute when everything is completed correctly.
