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 difficult for thieves to get into the vehicle.
The key chips come with unique serial codes which transmits a signal to the receiver in your car. The signal is then compared to the computer of the car when it is received. If the codes are identical then your car will begin to start. If not, it will not start at all. This is one of the main reasons why you should always keep a spare key in your car, especially if you have an electronic transponder.
