The keys themselves were metal and featured grooves that corresponded to the internal components of the ignition cylinder. As programming car key went on and technology advanced, more and more car manufacturers began blending electronic and physical protocols to prevent theft. These key systems are called transponder keys or chip keys and they're designed to make it more difficult for thieves to start the vehicle.
The key chips that are in the keys have a specific serial number, which transmits a signal to the receiver inside of your car.

This code matches the unique serial numbers that are stored in the computer of the car. This prevents unauthorised attempts to start the car, as only correct keys will be able.
This technology is believed to be more secure than traditional car keys because it makes it much more difficult for thieves to "hot wire" a vehicle and get it started.
