Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the model and manufacturer the process 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 car makers use the same programming protocols as auto tool manufacturers to allow them to develop hardware and software for locksmiths working in automotive vehicles.
Transponder Chips
Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit low-level radio waves. They have 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 stop the engine.

Transponder chips have drastically reduced the number of thefts.
When you insert the transponder keys in the ignition the signal is picked up by an antenna that is concealed around the barrel. The antenna is programmed with the frequency of the chip in the key. The onboard computer in the car will recognize the key as being valid and will allow fuel flow and start the starter. start the engine.
