The majority of cars had basic keys systems until the turn of the 21st century. Keys themselves were metal and had grooves that matched the internal components of the ignition cylinder. As technology advanced, more and more car manufacturers began to combine physical and electronic protocols to stop theft. Key systems like these are also referred to as transponder keys or chips keys are designed to make it difficult for thieves to start a vehicle.
The key chips inside the keys have a specific serial number, which transmits an electronic signal to the receiver in your car. The signal is compared with the car's computer when it is received. If the codes match, the car will start. If the codes don't match, your car won't even start. This is the reason you should keep an extra car key especially if the system is transponder-based.

The chip absorbs the energy and then transmits a radiofrequency signal that contains an identification code. The code is matched to the unique serial numbers that are stored in the computer system of the car. This prevents unauthorised attempts to start the car, since only the right key can start the car.
This technology is believed to be more secure than traditional keys for cars because it makes it harder for a thief to "hot wire" a vehicle and start it.
