The majority of cars had basic keys systems prior to the turn of 21st century. Keys were made from metal and featured grooves that match the internal components of the ignition cylinder. As technology advanced, more and more automobile makers began to mix electronic and physical protocols in order to prevent theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it difficult for thieves to start the vehicle.
The key chips in the keys have a unique serial number, which transmits signals to the receiver inside of your car. The signal is compared with the car's computer when it is received. If the codes are identical then your car will begin to start. If the codes aren't compatible, your car won't even start. This is one of the primary reasons you should keep a spare key for your vehicle, especially when you use an electronic transponder.

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 in the car's computer system. This prevents an unauthorized attempt to start the car, as only the correct key will be able to do so.
The technology is believed to be more secure than conventional car keys because it makes it difficult for thieves to "hot wire" an automobile and get it started. But it's not foolproof, and thieves have found ways to evade and defy the system - which means that even cars equipped that have transponder keys aren't protected from theft.
