As technology advanced, more and more car manufacturers began to combine physical and electronic protocols in order to prevent theft. These key systems are known as transponder keys or chip keys and they're designed to make it difficult for thieves to start the vehicle.

The key chips come with a unique serial code which transmits a signal to the receiver in your car. When the signal is received it is compared to an existing code in the car's computer. If the codes match, the car will start. If not, it won't start at all. This is one of the main reasons you should keep a spare key on your vehicle, especially if you have a transponder-based system.
