As technology advanced, more and more automobile makers began to combine electronic and physical protocols to avoid theft. These key systems are known as transponder keys or chip keys and are 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 inside your car. The signal is then compared to a code in the computer of the car when it is received. If the codes are similar, your car will begin. If not, it will not start at all. This is one of the primary reasons you should keep a spare key in your vehicle, particularly in the case of an electronic transponder.

This code matches the unique serial numbers in the computer system of the car. This prevents any attempts by anyone else to start the car, as only correct keys will be able.
