Automotive Locksmith Key Programming

Most modern-day cars require some kind of key programming. Depending on the car's maker and model, the procedure can be as easy as programming onboard using a spare key that works or as complex as OBD2 or EEPROM programming.

The majority of US and Asian car manufacturers share their programming protocols with auto tool makers to allow them to develop software and hardware for locksmiths working in automotive vehicles.

Transponder Chips

Transponder chips are found in a lot of modern cars to stop theft of cars. These are microchips in the form of computers which emit radio signals of low-level. The microchips have a unique serial number which authenticates your keys when you insert it into the ignition barrel. If your car doesn't recognise the signal it will stop the engine.
