The keys themselves were just metal and had grooves that were connected to the internal parts of the ignition cylinder. As technology advanced, more and more car makers began to mix electronic and physical protocols to stop theft. These key systems are called transponder keys or chip keys, and are designed to make it difficult for thieves to open the vehicle.

The key chips that are in the keys have a specific serial number that transmits a signal to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes are identical the car will begin to begin to start. If not, it will not start at all. This is one of the primary reasons to keep a spare key for your vehicle, especially if you have transponder-based systems.
