It's part of the immobilizer to prevent thieves from using a stolen vehicle key to start the car. Transponder signals are received by a detector near the ignition that determines the serial number from the transmission. If the number is in line, the car will begin. The majority of cars built in the last two decades utilize transponder keys. They are also used on aircrafts. Air traffic control uses these to identify friendly aircraft with a coded signal called IFF (Identification friend or foe). Certain aircrafts have mode C or mode S transponders that transmit the identifying codes and altitude information to ATC. They also include systems to avoid collisions. The metal parts of a standard Saab key are easy to duplicate, however the microchip that connects to the immobilizer is hard to duplicate. It is important to protect these keys when you own one. Anyone who owns a Saab should have at least two keys that are functional for their car. If you lose just one, it will cost you lots of money to replace it. You'll need to purchase an extra computer module, a second key, and program the car to convince it you're not attempting to take it. Immobilizers Immobilizers are an additional layer of protection against hotwiring. They prevent the engine from starting unless the transponder in the key fob is correct. In addition many cars that have immobilizers are equipped with a warning symbol on the instrument cluster that indicates the key isn't contained. If you lose your keyfob, you'll need to go to a dealer to deactivate it and get a new one. These systems rely on encryption of data between the transponder system and the vehicle. However, recent research has shown that these encryption sequences are too easy for computers to break. Hackers can bypass them by analyzing the messages transmitted back and forth over the CAN bus. These systems are more advanced than the traditional immobilizers that rely on one fixed code. Modern models have a system that rolls or changes codes to ensure that the systems are secure. Hackers are still able to hack these codes and use keys to open your vehicle. To overcome this issue, the DST80 has a longer code to make it more difficult to determine. Sadly, researchers were able to break this too. It is essential to keep your keyfob with you, even when not using it.
