However, as time progressed and technology improved as it did, car manufacturers began blending physical and electronic protocols to prevent theft. These key systems are known as transponder keys or chip keys, and they're designed to make it more difficult for thieves to open the vehicle.

The key chips come with a unique serial code which transmits a signal to the receiver in your car. The signal is compared to an identifier in the car's computer when it is received. If the codes are identical the car will begin to begin to start. If not, it will not start at all. This is why it is important to keep a spare car key, especially if the system is transponder-based.
