This can be accomplished by inserting a flathead screwdriver in the slot in the middle of the key fob. After a little effort you will be able of splitting the key. Remotes Modern Saab automobiles do not have keys made of metal to lock their cars. Rather they have an immobilizer system based upon the recognition of a specific chip embedded into each key. This is why a particular type of key is needed to unlock the car, and then insert it into the ignition. It is for this reason that an Saab owner should always have an extra. The traditional metal keys can be copied easily, but the real issue is that the electronic part of a key-fob must be connected to a specific vehicle in order to function. This process is carried out within the car's computer modules, which are called CIM (Column Integration Module) or TWICE (Theft Warning Integrated Central Electronics). If you lose your only functioning key in the process, it will cost your dealer a substantial amount to replace these modules as well as to program the new key.

Transponders A transponder can be described as an electronic chip inside a key fob that emits a unique coded signal. It's part of an immobilizer that stops thieves from using stolen keys to start your car. The transponder signal from the key are detected by the receiver located near the ignition. The receiver is able to decode the serial numbers that are generated by the transmission. If the numbers match the car's serial number, it starts. Transponder keys can be found in the majority of cars built in the past two decades. They are also utilized on airplanes. Air traffic control utilizes them to identify friendly aircraft through the use of a coded signal known as IFF (Identification of Friend or Foe). Certain aircrafts are equipped with mode C or mode S transponders that transmit identifying codes and altitude information to ATC. They also include systems to avoid collisions. The metal parts of the standard Saab Key are easy to duplicate. However, the microchip which communicates with the immobilizer may be difficult to copy. If you have one of these, it's essential to ensure its security. Every Saab owner should have two working keys. If you lose the only one, it will cost you a lot to replace it. You'll need a special computer module and a second key and program the vehicle to convince it that you're not trying to take it. Immobilizers Immobilizers are a further safeguard to stop thieves from hotwiring your car. They're designed to prevent the engine from starting unless the transponder is in the correct key fob. In addition to that many cars with immobilizers also display an alert symbol in the instrument cluster which indicates the key isn't in. If you lose your key fob, you'll need to take it to an authorized dealer to have it removed from the system and obtain a replacement. These systems are based on the encryption of data between the transponder system and the vehicle. Recent research has shown that these encryption sequences can be accessed by computers. Hackers could bypass them by reading the messages transferred back and forth across the CAN bus. These systems are more sophisticated than traditional immobilizers which use one fixed code. The newer models feature the capability of changing or rolling codes to ensure they are secure. Hackers can still hack these codes and use keys to start your vehicle. In an effort to solve this issue the DST80 was created with a longer sequence to make it harder to deduce. Researchers were also able to crack it.
