As technology advanced, more and more car makers began to mix electronic and physical protocols in order to prevent theft. Key systems, also known as transponder keys or chips keys, are designed to make it harder for thieves to steal an automobile.
The key chips come with a unique serial code which transmits a signal to the receiver in your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes match, the car will start. If the codes aren't compatible, your car won't even start. This is why you should keep an extra car key, particularly if your system is based on transponders.
