This can be accomplished by inserting a flathead screwdriver into the slot located in the middle of the key fob. After a short amount of work the key should split open. Remotes Modern Saab automobiles do not have keys made of metal to secure their vehicles. Instead, they utilize an immobilizer device that is built around recognition of a chip embedded into every key. That is why the car only starts when a certain type of key (called a “key-fob”) is used to unlock it, and then insert it into the ignition. It is for this reason that anyone who is a Saab owner should always have a spare. The classic metal keys are easy to duplicate, but the real problem is that the electronic component of a key-fob needs to be matched with a specific car to allow the key to function. This is accomplished through the computer modules of the car, known as CIM (Column Integration Modul) or TWICE. If you lose your only functioning key in the process, it will cost your dealer a lot of money to replace these modules and to program the new key. A local locksmith can reprogram the EEPROM inside the car's computer to give you a new key, saving you 50 percent or more than dealers charge! We suggest you contact us as soon as possible in the event that you lose your key. This will allow you to avoid the cost of the dealership. Transponders A transponder can be described as an electronic chip inside a key-fob which sends out a unique coded signal. It's part of the immobilizer that prevents thieves from using a stolen vehicle key to open the door. The transponder signals that the key emits are detected by the receiver near the ignition. The receiver decodes serial numbers of the transmission. If the number matches the car will begin. Transponder keys are found in the majority of cars built in the past two decades. They are also used on aircrafts. Air traffic control makes use of these to identify friendly aircraft with an encoded signal known as IFF (Identification friend or foe). Certain aircraft are equipped transponders in mode C or S that transmit the identification codes and altitudes to ATC. They also include systems for collision avoidance. The metal components of a typical Saab key are simple to duplicate, but the microchip that communicates with the immobilizer is hard to duplicate. It is important to secure these keys when you own one. Anyone who owns a Saab must have at a minimum two keys that are functional for the car. If you lose the sole one the cost will be an enormous amount to replace it. It will require a new, specialized computer module, as well as the cost of a second key as well as programming to convince the car that you aren't trying to steal it. Immobilizers Immobilizers offer an additional layer of protection against hotwiring. They're designed to prevent the engine from starting unless the transponder is located on the proper key fob. The majority of vehicles with immobilizers display a warning symbol in the instrument cluster to signal that the key is not in the. If you lose your key fob you'll need to take it to an authorized dealer to have it removed and then get a replacement. These systems rely on encryption of data between the transponder system and the car. Recent studies have shown that these encryption sequences can be cracked by computers. Hackers are able to bypass them by analyzing the messages transmitted back and forth over the CAN bus. These systems are more advanced than conventional immobilizers, which use one fixed code. The latest models come with a system of changing or rolling codes to make them more secure. Hackers can still crack these codes and use keys to start your vehicle. To address G28 , the DST80 has an extended code that makes it more difficult to determine. Researchers were also able to get it to work. This is why it's essential to always keep your key fob in your purse when you're not using it.
