The keys themselves were just metal and had grooves that matched the internal components of the ignition cylinder. However, as time progressed and technology improved, more and more automobile manufacturers began to combine physical and electronic protocols to protect against 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 transmits a signal to the receiver inside your car. The signal is compared with a code in the computer of the car when it is received.
