The keys themselves were just metal with grooves that corresponded to the internal parts of the ignition cylinder. However, as time progressed and technology improved and improved, car manufacturers began blending physical and electronic protocols to protect against theft. These key systems are called transponder keys or chip keys, and are designed to make it harder for thieves to get into the vehicle.

The key chips come with a unique serial code that sends a message to the receiver in your car. The signal is compared to the computer of the car when it is received. If the codes are similar, your car will begin to start. If not, it will not start at all. This is one of the main reasons you should keep a spare key on your car, especially if you have an electronic transponder.
