Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Depending on the model and manufacturer, the process may be as simple as using a spare key to program the onboard computer or as complicated as EEPROM or OBD2 programming.

Transponder Chips
Most modern cars are equipped with transponder chips in order to prevent theft. These are tiny computer microchips which emit radio waves at a low level. They have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal, the engine will be shut down. This technology has been a huge success in preventing theft of cars.

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