Key systems like these also known as transponder keys or chips keys, are designed to make it more difficult for thieves to open a vehicle.
The key chips that are in the keys have a specific serial number that sends an electronic signal to the receiver inside of your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes match, the car will 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.
