These key systems are referred to as transponder keys or chip keys and they're designed to make it difficult for thieves to get into the vehicle.
The key chips that are in the keys have a specific serial number, which transmits an electronic signal to the receiver inside your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes match the car will begin to begin to start. If the codes don't match, then your car won't even start. This is why you should keep an extra car key, especially if your system is based on transponders.
