These keys tend to break easily and aren't durable. Many people don't even have a spare key, which poses an extremely risky safety issue in the case of an emergency or an accident. You'll pay around $400 to the dealer to add an additional key. You'll need to purchase an additional key and transponder, and get the one you already have programmed to the car. The dealer uses a Tech-2 tool to perform this process. The process is straightforward, but you will require some mechanical expertise to successfully add the key. This is why it's best to leave the task to experts. The first step is taking the emergency key from its case. This can be done by inserting a flathead screwdriver in the slot located in the middle of the key fob. After a few minutes of work the key will split open. Remotes The latest Saab cars do not use traditional keys made of metal for security. Instead, they use an immobilizer system that is built around recognition and a unique chip embedded into every key. This is why a particular type of key is needed to unlock the car, and then insert it into the ignition. This is the reason that anyone who is a Saab owner should always carry a spare. The classic metal keys can be easily copied however the issue is that the electronic part of a key-fob must be matched to a specific vehicle in order for it to work. This matching is done in the computer modules of the car, referred to as CIM (Column Integration Modul) or TWICE. If you lose your sole working key and it costs the dealer a considerable amount to replace these modules and program the new key. Local locksmiths can modify the EEPROM chip inside the car computer to create an entirely new key. This could cost you as much as 50% of what dealer charges. We recommend you call us as soon as possible should you lose your key. This will help you save money by not having to pay a dealership. Transponders A transponder or electronic chip, is an electronic chip that is incorporated inside the key fob. It sends an unique coded message. It is part of the immobilizer system that prevents thieves from using a stolen key to start your vehicle. Transponder signals are picked up by a receiver close to the ignition, which interprets the serial number from the transmission. If the number matches the car will begin. Most cars built in the last two decades use transponder keys. These are also used in airplanes. Air traffic control makes use of these to identify friendly aircraft by using an encoded signal called IFF (Identification friend or foe). Certain aircraft are equipped transponders in modes C or S which transmit the identification codes and altitudes to ATC. They also provide systems for collision avoidance. The metal parts of the standard Saab Key are simple to duplicate. However, the microchip which communicates with the immobilizer can be difficult to duplicate. It is essential to protect these keys if you own one. Every Saab owner should have two keys that work. You'll have to pay a lot of money should you lose only one key. You'll need a special computer module as well as a new key and program the vehicle to convince it you're not attempting to take it. Immobilizers Immobilizers add another layer of protection against hotwiring. They are designed to stop the engine from running unless the transponder is in the proper key fob. Most cars with immobilizers also display a warning symbol in the instrument cluster to indicate that the key is not inside. If you lose your key fob you'll need to take it to an authorized dealer to get it removed from the system and obtain the replacement. These systems are based on encryption of the data that flows between the transponder and the car's system. However, recent studies have shown that these encryption sequences are too easy for computers to crack. Therefore, they are able to be snuffed out by hackers who can read the messages that are sent back and forward on the CAN bus. These systems are far 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. Hackers are still able to hack these codes and use keys to start your vehicle. To address this issue, the DST80 has a longer code to make it more difficult to guess. Researchers were also able break it. It is important to keep your keyfob with you, even when not using it.
