The keys themselves were just metal and featured grooves that matched the internal components of the ignition cylinder. As time passed and technology improved and improved, car manufacturers began blending physical and electronic protocols to prevent theft. These key systems also known as transponder keys or chips keys, are designed to make it more difficult for thieves to start a vehicle.

The key chips contain unique serial codes that transmits a message to the receiver inside your car. The signal is then compared to the computer of the car when it is received. If the codes match, your car will begin to start. If not, it won't start at all. This is why you should keep a spare car key, especially if the system is based on transponders.
