Before the turn of the 21st century, most cars used basic key systems. The keys were made of metal and had grooves to correspond to the internal parts in the ignition cylinder. However, as time progressed and technology improved as it did, automobile manufacturers began blending physical and electronic protocols to stop theft. Key systems like these also known as transponder keys or chips keys, are designed to make it harder for thieves to open an automobile.

The key chips inside the keys have a unique serial number that sends signals to the receiver inside your car. The signal is compared to a code in the computer of the car when it is received. If the codes match, your car will start. If not, it will not start at all. This is one of the primary reasons why you should always keep a spare key on your car, especially in the case of a transponder-based system.

This energy is absorbed by the chip, which then transmits the radio frequency signal, which includes an identification code that is matched with the unique serial number of the car's computer system. This will prevent any unauthorized attempts to start the car since only the right key will be able to do so.

This technology is thought to be more secure than the traditional car key, as it makes it harder for thieves to "hot wire" the vehicle and start it.
