Instead, they employ an immobilizer that is built on recognition and a unique chip embedded in every key. This is the reason a particular kind of key is required to unlock the car and put it into the ignition. This is one of the main reasons for a prudent Saab owner to always have a spare key available. The classic keys made of metal are easy to duplicate, but the real problem is that the electronic component of a key-fob must be matched to a particular car in order for the key to work. This is accomplished through the computer modules of the car, called CIM (Column Integration Modul) or TWICE.

Transponders A transponder, also known as an electronic chip, is an electronic chip that is placed inside the key fob. It sends an unique coded message. It's part of the immobilizer that prevents thieves from using stolen car key to start it. The transponder signals are received by a detector near the ignition, which interprets the serial number from the transmission. If the serial number matches, the car will start. The majority of cars built in the last two decades utilize transponder keys. They are also used in aircrafts. Air traffic control makes use of them to identify friendly aircraft using a coded signal, IFF (Identification Friend or Foe). Certain aircrafts have mode C or mode S transponders which transmit the identifying codes and altitude information to ATC. They also offer collision avoidance systems. The metal parts of a standard Saab key are simple to duplicate, but the microchip that connects to the immobilizer is hard to copy. If you own one of these, it is vital to protect it. Everyone who owns a Saab must have at minimum two keys that work for their car. If you lose just one and you lose it, it will cost a lot to replace it. You will need to buy an extra computer module and a second key and program the vehicle to convince it you're not trying to steal it. Immobilizers Immobilizers provide an additional layer of protection against hotwiring. They stop the engine from being started without ensuring that the transponder on the key fob matches. The majority of vehicles with immobilizers display a warning icon in the instrument cluster to signal that the key is not in the. If you lose your keyfob you'll have to visit a dealer to deactivate it and get a new one. These systems are based on encryption of the data that flows between the transponder and the car's system. However, recent studies have discovered that these encryption sequences are too easy for computers to crack. This means that they can easily be manipulated by hackers who can understand the messages going back and forward on the CAN bus. These systems are more sophisticated than traditional immobilizers which use one fixed code. The latest models come with a system of changing or rolling codes to make them more secure. The issue with these versions is that hackers are still able to find ways to break the code and use the key to start your car. To fix this issue the DST80 has an extended code that makes it more difficult to determine. Sadly, researchers were able to solve this problem as well. Therefore, it's crucial to always keep your key fob with you when you're not using it.
