Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Based on the model and make the procedure could be as simple as using a spare key to program the onboard computer or as complicated as OBD2 programming or EEPROM.
The majority of US and Asian automakers use the same programming protocols as auto tool makers, so they can design tools or hardware for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves at a low level. The microchips are equipped with a unique serial number which authenticates your key when you insert it 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 an enormous success in preventing auto theft.

Transponder chips have dramatically reduced the number of thefts.
When you insert the transponder keys in the ignition, the signal is picked up by an antenna that is hidden within the barrel. This antenna is programmed to detect the particular frequency of the chip inside the key. The computer onboard of the car will then recognize the key as valid and allow fuel flow and power the starter to start the engine.

The majority of key fobs are equipped with security features that make it difficult for attackers to duplicate and copy the signals they transmit. Some key fobs have pseudo-random code generators, which generate a different unlock code every time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
