Automotive Locksmith Key Programming
The majority of modern cars require some kind of key programming. Based 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 OBD2 programming or EEPROM.
Most US and Asian automakers use the same programming protocols as auto tool makers, which means they can develop hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are used in many newer cars to prevent car theft. These are tiny computer microchips which emit radio waves of low-level. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has proven to be a huge success in preventing theft of cars.

The antenna is programmed with the frequency of the chip inside the key. The onboard computer in the car will recognize the key as valid and allow fuel flow and power the starter to start the engine.

This means that if you get your keys replaced, you'll have to have the new key fob programed to the car in order for it to work.
