Any hardware store can make you an entirely new car key, however the real challenge lies in integrating it with your vehicle. A key that has been reprogrammed will need to be compatible with the exact identification number of your vehicle, or it won't start the engine. Transponder chips, used to prevent car theft, are a common feature of modern cars. The chip is a microcircuit that emits a radio frequency signal when the key is put in the ignition. The car then recognizes the signal and starts the engine if it is in line with the original frequency that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it more difficult for car thieves with no experience to wire a vehicle and start it. The key and the chip are linked by a circuit board that includes an induction coil. When the key is put in the ignition, a magnetic field is created around the transponder. This generates a signal, which is absorbed by the coil and sent to the key identification number. The key's identification number is then transmitted back to the car, and the engine starts when the identification number matches.
