These key systems are referred to as transponder keys or chip keys and they're designed to make it harder for thieves to get into the vehicle.
The key chips that are in the keys have a unique serial number that transmits an electronic signal to the receiver inside your car. The signal is then compared to a code in the computer of the car when it is received. If the codes match then your car will begin to start. If the codes aren't compatible, your car won't even start. This is why it is important to keep an extra car key, particularly if your system is transponder-based.
