Automotive Locksmith Key Programming
Modern cars need some type of key programming. Based on the model and manufacturer the procedure could be as simple as using an extra key to program the onboard computer, or as complicated as OBD2 programming or EEPROM.

Transponder Chips
Transponder chips are found in many newer cars to guard against theft of vehicles. These are tiny computer microchips which emit radio waves at a low level. The microchips have an unique serial number that authenticates your key whenever you insert it into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has proven to be extremely successful in preventing theft of cars. It also saves many car owners a significant amount of money as they don't have to buy new their vehicles.

The computer onboard of the car will then recognize the key as being valid and allow fuel flow, power the starter or begin the engine.

If you change your keys, you will need to program the new key fob into the car to allow it to function.
This is done by using a tool for programming keys for cars that are compatible with the vehicle's brand. This tool allows the locksmith to connect to the OBD port (OBD) within the vehicle and then enter a programming mode. The key programming device can be a handheld device that's inexpensive or one that is sophisticated and capable of doing more than just programming keys (like reading the eeprom file inside the ECU).
