As technology advanced, more and more car makers began to mix physical and electronic protocols in order to prevent theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it more difficult for thieves to open the vehicle.
The key chips that are in the keys have a unique serial number that transmits signals to the receiver in your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are compatible, then your car will begin to start. If not, it won't start at all. This is one of the primary reasons you should keep a spare key on your car, especially if you have transponder-based systems.
