If you lose either of these, you'll not be able to start your vehicle until you get the second. You can save a lot by purchasing it yourself instead of paying the dealer.

The 03-11 SAAB owners face a unique issue with their car keys. These key fobs aren't all that durable and they tend to break quite easily. Many people don't even own a spare key, which poses an extremely risky safety issue in the situation of an emergency or an accident. It will cost you around $400 to the dealer if you want to add an extra key. You'll need a new key, transponder, and also to have your existing key programmed. This is accomplished using the special tool known as a Tech-2 that dealers have. The process is straightforward, but you will need to have some mechanical knowledge to successfully add the key. It's best to leave this to a professional. The first step is to remove 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 bit of work, the key will split open. Remotes Modern Saab automobiles do not have keys made of metal to lock their cars. Instead, they use an immobilizer system built around recognition of a chip that is embedded in each key. This is why a specific type of key is needed to unlock the car and put it into the ignition. This is one of the main motives for a smart Saab owner to always keep a spare key handy. The traditional metal keys can be easily copied but the issue is that the electronic component of a key-fob needs to be matched to a specific vehicle in order to function. This matching takes place in the computer modules of the car, known as CIM (Column Integration Modul) or TWICE. If you lose your sole working key in the process, it will cost your dealer a lot of money to replace these modules and to program the new key. G28 Car Keys can modify the EEPROM chip of your car computer to make a new key. This will reduce your costs by up to 50% of the cost dealers would charge. We recommend you call us as soon as possible in the event that you lose your key. This will allow you to avoid the expense of a dealership. Transponders A transponder or electronic chip, is an electronic chip that is placed in the key-fob. It sends an unicoded message. It's part of an immobilizer system to prevent thieves from using stolen keys to start your vehicle. The transponder signals from the key are detected by the receiver close to the ignition. The receiver decodes serial numbers from the transmission. If the number matches, the car starts. The majority of cars built in the last two decades use transponder keys. They are also used in aircrafts. ATC uses them to identify friendly aircraft with an encoded signal, IFF (Identification of Friend or Foe). Certain aircrafts are equipped mode C or mode S transponders that transmit identifying codes and altitude information to ATC. They also include systems for collision avoidance. The metal parts of a typical Saab key are simple to duplicate, however the microchip which communicates with the immobilizer is hard to copy. If you have one of these, it's very important to secure it. Every Saab owner should have two working keys. You will have to shell out a significant amount of money in the event that you lose your primary key. You will need to buy an extra computer module, a second key, and program the car to convince it that you are not trying to steal it. Immobilizers Immobilizers add another security measure to prevent thieves from hotwiring your vehicle. They stop the engine from being started until the transponder on the key fob is in order. The majority of vehicles with immobilizers display a warning indicator in the instrument cluster to signal that the key isn't inside. 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 the encryption of data between the transponder systems and the vehicle. Recent studies have shown that encryption sequences are able to be cracked by computers. They can also be bypassed by hackers who can read the messages that are sent back and forward on the CAN bus. These systems are more advanced than traditional immobilizers which use one fixed code. The latest models use a technology that alters or rolls codes to ensure that the systems are secure. The issue with these is that hackers can still find ways to crack the code and use a key to start your car. To overcome this issue, the DST80 has an extended code that makes it more difficult to guess. Researchers were also able get it to work. This is why it's essential to always keep your key fob with you when you're not using it.
