Automotive Locksmith Key Programming

Modern automobiles require some kind of key programming. Depending on the model and manufacturer the process could be as simple as using an additional key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.

Most US and Asian auto manufacturers use the same programming protocols as auto tool manufacturers, so they can create tools or hardware for automotive locksmiths.

Transponder Chips

Transponder chips are found in a variety of newer vehicles to stop theft of cars. These are tiny computer microchips that emit radio signals at a low level. They have a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your car doesn't recognise the signal it will shut down the engine.

This antenna is programmed to detect the particular frequency of the chip inside the key. The onboard computer in the car will then recognise the key as being valid and allow fuel flow and start the starter. start the engine.
