Automotive Locksmith Key Programming

The majority of modern cars require some form of key programming. Depending on the vehicle's make and model, the procedure could be as simple as programming onboard using an extra working key or as complex as OBD2 or EEPROM programming.

Transponder Chips

Transponder chips are in a lot of modern cars to guard against theft of vehicles. These are small computer microchips that emit radio signals at a low level. They have a unique serial number that authenticates your key when you connect it to the ignition barrel. If your vehicle doesn't recognize the signal it will shut down.
