As time passed and technology improved, more and more car manufacturers began blending electronic and physical protocols to stop theft. These key systems are also referred to as transponder keys or chips keys are designed to make it harder for thieves to start the vehicle.

The key chips contain unique serial codes that sends a message to the receiver inside your car. The signal is then compared to an identifier in the car's computer when it is received. If the codes are compatible, then the car will start. If not, it won't start at all. This is why it is important to keep an extra car key, especially if the system is based on transponders.
