These key fobs aren't all that durable and they tend to fall apart quite quickly. A lot of people don't have an extra, which could pose a risk to safety in an emergency. If you're considering adding an extra key for your car, it will cost about $400 at the dealer. You'll need to purchase an additional key and transponder, plus to program the current one to the car. This process is done with an instrument known as Tech-2. Tech-2, which dealers have. It is a simple process, but you'll need some mechanical skills to add the key. This is the reason it's better to leave it to an expert. The first step is to remove the emergency key from its case. Install a flathead into the slot located in the middle of your key fob. After a little effort you will be able of splitting the key. Remotes The newest Saab automobiles don't rely on traditional keys made of metal for security. Instead, they employ an immobilizer system that is built around recognition and a special chip that is embedded in every key. This is why the car can only start when a certain type of key (called”key-fob” or “key-fob”) is used to unlock it, and then insert it in the ignition. It is for this reason that anyone who is a Saab owner should always have a spare. The classic metal keys are easily copied, but the real issue is that the electronic component of a key-fob has to be matched to a specific vehicle in order to work. This matching takes place in the car's computer components that are known as CIM (Column Integration Module) or TWICE (Theft Warning Integrated Central Electronics). If you lose your only working key and it costs the dealer a considerable amount to replace these modules as well as to program a new key. Local locksmiths can modify the EEPROM chip of your car computer to create an entirely new key. This will cost you as much as 50% of what a dealer would charge. We recommend that you contact us as soon as possible when you lose your keys. This will help you save money by not having to pay buying a new key from a dealer. Transponders A transponder or electronic chip, is a tiny electronic chip that is embedded inside the key fob. It transmits an unicoded message. It is a part of the immobilizer, which prevents thieves from using stolen car key to open the door. The transponder signals are received by a device near the ignition, which interprets the serial number from the transmission. If the number matches, the car will begin. Most cars manufactured in the last two decades have transponder keys. These are also used in aircrafts. ATC uses them to identify friendly aircraft with a coded signal called IFF (Identification friend or foe). Certain aircraft have transponders in the mode C or S, which transmit the identification codes and altitudes to ATC. They also support collision avoidance systems. The metal parts of the standard Saab Key are easy to duplicate. However the microchip that communicates with an immobilizer could be difficult to copy. If you own one of these, it's vital to protect it. Every Saab owner should have two keys that work. If you lose the sole one that you have, it will cost a lot to replace it. It will require a new, specialized computer module, as well as the cost of a new key and programming to convince the car you aren't trying to steal it. Immobilizers Immobilizers are another layer of protection to stop thieves from hotwiring your vehicle. They are designed to stop the engine from starting unless the transponder is in the correct key fob. In addition the majority of vehicles with immobilizers will also display a warning symbol on the instrument cluster that indicates the key isn't in. If you lose your keyfob, you'll have to visit a dealer to deactivate it and get a new one. These systems are founded on encryption of data that is transmitted between the transponder and car's system. However, recent studies have shown that these encryption sequences are too easy for computers to hack. This means that they can easily be manipulated by hackers who can detect the messages that travel back and back on the CAN bus. These systems are more advanced than conventional immobilizers that use one fixed code. The latest models use a technology that changes or rolls codes to make the systems more secure. Hackers are still able to crack these codes and use keys to begin your vehicle. To address this problem, the DST80 was developed with a more lengthy sequence to make it more difficult to deduce. Sadly researchers were able to get around this. Therefore, it's crucial to always keep your key fob with you when you're not using it.
