As time went on and technology improved, more and more automobile manufacturers began blending physical and electronic protocols to prevent theft. These key systems are known as transponder keys or chip keys and they're designed to make it harder for thieves to start the vehicle.

The key chips inside the keys have a unique serial number that sends signals to the receiver inside your car. When the signal is received it is compared to an existing code in the car's computer. If the codes match, then your car will begin to start. If not, it will not start at all. This is the reason you should keep an extra car key, especially if the system is transponder-based.

The code is matched to the unique digital serial numbers that are stored in the car's computers. This helps prevent unauthorised attempts to start the car as only the correct key can perform the task.
