The keys themselves were just metal and had grooves that were connected to the internal components of the ignition cylinder. As technology advanced the number of car makers began to mix physical and electronic protocols to stop theft. These key systems also known as transponder keys or chips keys are designed to make it harder for thieves to open a vehicle.

The key chips come with a unique serial code that transmits a message to the receiver in your car. The signal is compared with the computer of the car when it is received.
