As technology improved the number of car makers began to mix electronic and physical protocols to avoid theft. Key systems like these, also known as transponder keys or chips keys are designed to make it harder for thieves to open a vehicle.

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 are identical, your car will begin. If not, it will not start at all. This is why you should keep a spare car key, particularly if your system is based on transponders.
