Automotive Locksmith Key Programming

Most modern-day cars require some type of key programming. Based on the model and make the procedure could be as simple as using an extra key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM.

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

Transponder Chips

Most modern cars are equipped with what are called transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves of low-level. They have a unique digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your car doesn't recognise the signal it will stop the engine.

The antenna is programmed with the frequency of the chip inside the key. The car's onboard computer will then detect that the key is valid and allow the fuel to flow, then power the starter or start it.
