As technology advanced, more and more car makers began to combine physical and electronic protocols in order to prevent theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it harder for thieves to start the vehicle.
The key chips inside the keys have a unique serial number, which transmits an electronic signal to the receiver inside your car. The signal is compared with an identifier in the car's computer when it is received. If the codes match then your car will start. If not, it won't start at all. This is one of the primary reasons you should keep a spare key in your vehicle, especially in the case of a transponder-based system.

This code matches the unique digital serial numbers that are stored in the computer system of the car. This prevents unauthorized attempts to begin the car as only the right keys can be used.
This type of technology is thought to be more secure than a traditional car key because it makes it harder for thieves to "hot wire" the vehicle and then start it.
