As technology improved, more and more automobile makers began to combine physical and electronic protocols to stop theft. These key systems are referred to as transponder keys or chip keys and are designed to make it harder for thieves to open the vehicle.
The key chips come with unique serial codes which transmits a signal to the receiver in your car. The signal is compared with the car's computer when it is received. If the codes are identical then your car will start. If the codes don't match, your vehicle won't start at all. This is why you should keep an extra car key, particularly if your system is transponder-based.
