Before the turn of the 21st century, the majority of cars had basic key systems. The keys themselves were just metal with grooves that matched the internal parts of the ignition cylinder. As technology improved, more and more car makers began to mix electronic and physical protocols in order to prevent theft. Key systems like these, also known as transponder keys or chips keys are designed to make it difficult for thieves to steal a vehicle.
The key chips come with a unique serial code which transmits a signal to the receiver inside your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes match, your car will start. If the codes aren't compatible, your car won't even start. This is one of the primary reasons why you should always keep a spare key in your vehicle, particularly when you use an electronic transponder.

This prevents unauthorized attempts to begin the car, as only correct keys will be able.
The technology is believed to be more secure than a traditional car key, as it makes it difficult for a criminal to "hot wire" the vehicle to start it.
