It is a part of the immobilizer, which prevents thieves from using a stolen car key to start it. The transponder signal is received by a detector close to the ignition, which decodes the serial number of the transmission. If the serial number matches the car's number, it will start. Transponder keys are found for the majority of automobiles manufactured in the past two decades. They are also utilized in airplanes. ATC uses them to identify friendly aircraft by using a coded signal called IFF (Identification friend or foe). Certain aircrafts are equipped with mode C or mode S transponders which transmit identifying codes as well as altitude to ATC. They also include systems to avoid collisions.

Immobilizers Immobilizers provide another security measure to prevent thieves from hotwiring your car. They're designed to prevent the engine from starting unless the transponder is in the correct key fob. Most cars with immobilizers also display a warning indicator in the instrument cluster to indicate that the key is not inside. If you lose your keyfob you will need to visit a dealer to disable it and then purchase a new one. These systems rely on the encryption of information between the transponder system and the vehicle. However, recent studies have found that these encryption codes are too easy for computers to crack. Hackers can bypass them by analyzing the messages that are transmitted back and forth over the CAN bus. These systems are superior to the traditional immobilizers which use a fixed code. Modern models have a system that changes or rolls codes to increase the security of the system. The issue with these versions is that hackers still have the ability to find ways to break the code and use keys to start your vehicle. To combat this problem the DST80 was developed with a longer sequence to make it more difficult to deduce. Sadly researchers were able to get around this. It's essential to keep your keyfob with you, even when not in use.
