Nearly all modern vehicles require some kind of transponder key or fob to operate, providing security and protection against theft.

While any hardware store can cut keys for you, the main challenge is making it function in conjunction with your particular car. The key has to be programmed to match the exact identification number on your car, otherwise it won't start.
Transponder chips, which are used to prevent car theft, are a common feature of modern cars. The chip is a microcircuit that transmits a radio frequency signals when the key is placed into the ignition. The car then scans for the signal and begins the engine if it is in line with the original frequency that was programmed into the vehicle. The car also shuts down if a frequency is not valid. This makes it harder for novice car thefts to hot-wire a vehicle and then turn it on.
A circuit board with an induction coil connects the key to the chip. When the key is placed in the ignition the magnetic field is generated around the transponder. This generates a signal, which is taken up by the coil and sent to the key's identification number. The key's identification number is then returned to the car and the engine is started if the identification number matches.
