The first step is to remove the emergency key from the case. Insert a flathead into the middle slot of your key fob. After a bit of work the key should split open. Remotes The latest Saab automobiles do not use traditional keys made of metal to provide security. Instead, they employ an immobilizer system based on the recognition and a unique chip that is embedded in each key. This is why a specific type of key is required to unlock the car and put it into the ignition. It is for this reason that the Saab owner should always carry a spare. The traditional metal keys can be copied easily however the issue is that the electronic component of a key-fob must be matched with a specific vehicle in order for it to work. This matching is performed in the car's computer modules, which are called CIM (Column Integration Module) or TWICE (Theft Warning Integrated Central Electronics). If you lose your only working key and you lose it, it will cost the dealer a considerable amount to replace these modules as well as to program the new key. Local locksmiths can reprogram the EEPROM chip in the car computer to create a new key. This can cost you as much as 50% of the cost dealers would charge. We suggest that you contact us as soon as possible in the event that you lose your key. This will help you avoid the expense of a dealership. Transponders A transponder, or electronic chip, is an electronic chip that is embedded in the key-fob. It transmits an individual coded message. It's part of an immobilizer system that prevents thieves from using stolen keys to start your vehicle. The transponder signals that the key emits are picked up by the receiver close to the ignition. The receiver is able to decode the serial numbers of the transmission. If the number is in line, the car starts. 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 these to identify friendly aircraft with an encoded signal called IFF (Identification friend or foe). Certain aircraft are equipped with transponders in modes C or S that transmit the identification codes and altitudes to ATC. They also provide collision avoidance systems. The metal parts on the standard Saab Key are simple to duplicate. However the microchip that communicates with the immobilizer can be difficult to copy. If you own one of these, it's vital to protect it. Anyone who owns a Saab should have at least two keys that function for the car. If you lose just one that you have, it will cost an enormous amount to replace it. You'll need a brand new, specialized computer module and the costs of a new key and programming to convince the car that you aren't trying to steal it. Immobilizers Immobilizers add another layer of protection to stop thieves from hotwiring your car. They are designed to stop the engine from running unless the transponder is on the correct key fob. In saab 9-3 key to that the majority of vehicles that have immobilizers are equipped with a warning symbol on the instrument cluster that shows the key isn't in. If you have lost your key fob, you'll need to take it to an authorized dealer to get it removed and then get an alternative. These systems are built around encryption of data that is transmitted between the transponder and the car's system. Recent studies have revealed, however, that these encryption sequences are able to be cracked by computers. Hackers could bypass them by reading the messages that are sent back and forth over the CAN bus. These systems are much more advanced than conventional immobilizers, which use a fixed code. The latest models use a technology which rolls or changes codes to ensure that the systems are secure. The problem with these codes is that hackers still have the ability to discover ways to break the code and then use keys to start your vehicle. To overcome this issue, the DST80 has a longer code to make it harder to figure out. Sadly researchers were able crack this as well. As such, it's important to keep your key fob with you when you're not using it.
