As technology improved, more and more car makers began to mix physical and electronic protocols to avoid theft. These key systems are also referred to as transponder keys or chips keys, are designed to make it difficult for thieves to open an automobile.
The key chips that are in the keys have a unique serial number that transmits a signal to the receiver inside of your car. The signal is then compared to an identifier in the car's computer when it is received. If the codes are identical, your car will begin. If the codes aren't compatible, your car will not even start. This is why it is important to keep an extra car key, especially if the system is based on transponders.
