As time went on and technology improved as it did, automobile manufacturers began blending electronic and physical protocols to prevent theft. These key systems, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to steal an automobile.

The key chips contain a unique serial code which transmits a signal to the receiver inside your car. When the signal is received, it compares it to an existing code in the car's computer. If the codes match, your car will start. If not, it won't start at all. This is why you should keep an extra car key particularly if your system is transponder-based.
