As technology advanced the number of car manufacturers began to combine 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 get into the vehicle.
The key chips come with a unique serial code that sends a message to the receiver inside your car. The signal is compared with the computer of the car when it is received. If the codes match, your car will start. If not, it will not start at all. This is one of the main reasons you should keep a spare key for your vehicle, particularly if you have transponder-based systems.
