Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the car's maker and model, the process can be as simple as onboard programming using a spare working key or as complex as OBD2 or EEPROM programming.

These are small computer microchips that emit low-level radio signals. reprogram car key are equipped with an unique serial number that authenticates your keys when you plug it into the ignition barrel. If your car isn't able to recognize the signal it will shut down the engine. This technology has proven to be an immense success in stopping auto theft.

When you insert the transponder key into the ignition, the signal is received by an antenna hidden around the barrel. This antenna is programmed with the frequency of the chip within the key. The computer onboard of the car will then recognise the key as being valid and allow fuel flow and power the starter to start the engine.
