The majority of cars had basic keys systems up until the turn of 21st century. Keys themselves were metal with grooves that matched the internal components of the ignition cylinder. However, as time progressed and technology advanced, more and more automobile manufacturers began to combine electronic and physical protocols to stop theft. Key systems like these, also known as transponder keys or chips keys, are designed to make it difficult for thieves to open a vehicle.
The key chips contain unique serial codes which transmits a signal to the receiver in your car. When the signal is received it is compared to an existing code in the car's computer.

This helps prevent unauthorised attempts to start the car, because only a valid key will be able to start the car.
