Automotive Locksmith Key Programming
The majority of modern cars require some kind of key programming. Depending on the model and manufacturer the procedure could be as simple as using a spare key to programme the computer onboard, or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian auto manufacturers share their programming protocol with auto tool makers, so they can develop hardware or software for locksmiths in the automotive industry.
Transponder Chips
Transponder chips are in a lot of modern cars to prevent car theft. These are tiny computer microchips which emit radio waves of low-level. The microchips have a unique serial number that authenticates your key when you connect it to the ignition barrel. If your vehicle isn't able to recognize the signal it will shut down. This technology has proven to be extremely successful in preventing theft of cars. It has also saved many car owners a significant amount of money since they don't need to replace their vehicles.

When you insert the transponder keys in the ignition the signal is received by an antenna that is hidden within the barrel. This antenna is programmed to read the specific frequency of the chip within the key. The onboard computer of the car will then recognize the key as being valid and allow fuel flow, power the starter or start the engine.
