As his explanation went on and technology advanced as it did, automobile manufacturers began blending electronic and physical protocols to prevent theft. These key systems are known as transponder keys or chip keys and they're designed to make it difficult for thieves to open the vehicle.
The key chips contain unique serial codes which transmits a signal to the receiver in your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes are identical then your car will begin. If not, it will not start at all. This is why it is important to keep an extra car key especially if the system is transponder-based.
