The majority of cars had basic keys systems until the turn of 21st century. The keys themselves were just metal and had grooves that corresponded to the internal parts of the ignition cylinder. As technology improved the number of car makers began to mix physical and electronic protocols to stop theft. Key systems, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to steal a vehicle.

The key chips in the keys have a specific serial number, which transmits an electronic signal to the receiver inside of your car. The signal is compared to an identifier in the car's computer when it is received. If the codes match the car will begin to begin. If not, it will not start at all. This is one of the main reasons you should keep a spare key in your car, especially if you have transponder-based systems.

Transponder Keys

Transponder keys, also referred to as chip keys, come with a microchip embedded in the head of the key.

The energy is absorbed by the chip and sends back the radio frequency signal, which includes an identification code that matches with the unique serial number in the car's computer system. This stops unauthorised attempts to start the car as only the correct keys will be able.

This type of technology is thought to be more secure than a conventional car key, as it makes it more difficult for a criminal to "hot wire" the vehicle and start it. But it's not foolproof and thieves have discovered ways to deceive and defy the system - which means that even cars equipped with transponder keys are not protected from theft.
