Certain cars with more modern technology have rolling key technology that prevents thieves from using a stolen vehicle's key to open it.

Transponder chips

Car keys with transponder chips require a special programming to function. Any hardware store can make you an entirely new car key, but the real challenge lies in integrating it with your vehicle. The key needs to be programmed to match the exact identification number of your car, otherwise it will not start.

Transponder chips, used to protect cars from theft are a standard feature of modern cars. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is put in.

This makes it more difficult for car thieves with no experience to hot wire a vehicle and start it.

The chip and the key are linked by a circuit board that includes an induction coil. When the key is inserted into the ignition it creates a magnetic field around the transponder. This creates a signal which is taken up by the coil and then transmitted to the key's identification. The ID number of the key is transmitted back to the vehicle, and if it matches, the engine will start.
