If the number matches the car will start. The majority of cars built during the past two decades use transponder keys. They are also used on airplanes. Air traffic control uses these to identify friendly aircraft using an encoded signal known as IFF (Identification friend or foe). Certain aircrafts are equipped mode C or mode S transponders that transmit identifying codes and altitude to ATC. They also have collision avoidance systems.

Immobilizers Immobilizers provide an additional layer of protection against hotwiring. They stop the engine from starting unless the transponder inside the key fob is valid.

Recent research has revealed, however, that these encryption sequences can be broken by computers. They can also be snuffed out by hackers who are able to read the messages that are sent back and back on the CAN bus. They are more advanced than the conventional immobilizers that use a fixed code. Modern models have a system that rolls or changes codes to ensure that the systems are secure. The issue with these is that hackers still have the ability to find ways to break the code, and then use the key to start your car. To combat this problem, the DST80 was designed with a longer sequence that would make it more difficult to guess. Researchers also managed to break it. It is essential to keep your keyfob with you even when you're not using it.
