As technology improved, more and more automobile makers began to mix electronic and physical protocols in order 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 that are in the keys have a specific serial number, which transmits a signal to the receiver inside of your car. When the signal is received it compares it with an existing code in the car's computer. If the codes match, then the car will start. If the codes don't match, your car won't even start. This is one of the primary reasons why you should always keep a spare key for your vehicle, particularly in the case of transponder-based systems.
