As time went on and technology advanced, more and more automobile manufacturers began blending physical and electronic protocols to prevent theft. These key systems are called transponder keys or chip keys and are designed to make it harder for thieves to start the vehicle. The key chips that are in the keys have a unique serial number that transmits an electronic signal to the receiver in your car.
