Depending on your vehicle's model and manufacturer the process could be as simple as using a spare key to programme the computer onboard, or as complicated as EEPROM or OBD2 programming. Most US and Asian car makers share their programming protocols with auto tool makers so that they can develop hardware and software for locksmiths in the automotive industry to use. Transponder Chips Transponder chips are in many newer cars to guard against theft of vehicles. These are tiny computer microchips that emit low-level radio signals. They are equipped with a unique digital serial number that authenticates the key to your car when it is plugged 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 extremely successful in preventing theft of cars. It has also saved many car owners a lot of money as they don't have to replace their cars.

Transponder chips have drastically reduced the number of thefts. When you insert a transponder key into the ignition, it will send an electrical signal that is picked up by a hidden antenna around the barrel of the ignition. This antenna is programmed with the frequency of the chip within the key. The onboard computer in the car will then recognise the key as valid and allow fuel flow and start the starter. begin the engine.

For instance, a “smart key” that lets you call your car to parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
