As technology advanced, more and more car manufacturers began to combine physical and electronic protocols in order to prevent theft. Key systems like these, also known as transponder keys or chips keys, are designed to make it difficult for thieves to start the vehicle.
The key chips come with a unique serial code that sends a message to the receiver inside your car. The signal is compared with the car's computer when it is received. If the codes are compatible, then your car will begin to start. If not, it will not start at all. This is why you should keep an extra car key especially if the system is based on transponders.

This is to prevent unauthorized attempts to begin the car since only correct keys will be able.
The technology is believed to be more secure than the traditional car key since it makes it harder for a thief "hot wire" the vehicle to start it. It's not foolproof, and thieves have found ways to evade detection and defeat the system. So even cars with transponder key are not immune to theft.
