As technology advanced the number of car makers began to combine physical and electronic protocols in order to prevent theft. Key systems like these are also referred to as transponder keys or chips keys, are designed to make it difficult for thieves to start the vehicle.

If the codes match then your car will begin to start. If not, it won't start at all. This is the reason you should keep an extra car key, especially if your system is based on transponders.
