Many people don't own a spare, which can be a security risk in an emergency. If you're looking to add an additional key, it will cost you around $400 at the dealer. You'll have to purchase the new key and transponder, plus have the existing one programmed to the car. This process is done with an instrument known as a Tech-2, which the dealer owns.

The first step is to remove the emergency key from the case. This can be done by inserting a flathead screwdriver in the slot that is located in the middle of the key fob. After a few minutes of work you should be able to split the key. Remotes The latest Saab automobiles don't rely on traditional keys made of metal to provide security. Rather they have an immobilizer system based on the recognition of a unique chip inside every key. This is why a specific kind of key is needed to unlock the car and then insert it into the ignition. This is among the primary reasons for a responsible Saab owner to always keep a spare key handy. The traditional metal keys can be copied easily but the problem is that the electronic part of a key fob needs to be matched with a specific vehicle in order to function. This matching is performed in the car's computer module and are referred to as CIM (Column Integration Module) or TWICE (Theft Warning Integrated Central Electronics). The dealer will charge you a lot to replace the modules and program a new one in case you lose the only key.

Transponders A transponder, also known as a electronic chip, is a tiny electronic chip that is incorporated in the key-fob. It sends an unique coded message. It's a component of the immobilizer, which prevents thieves from using a stolen car key to start it. The transponder signals from the key are detected by the receiver close to the ignition. This receiver decodes the serial numbers that are generated by the transmission. If the number is in line, the car will start. Most cars manufactured in the last two decades utilize transponder keys. They are also used in airplanes. Air traffic control makes use of these to identify friendly aircraft using a coded signal called IFF (Identification friend or foe). Certain aircrafts are equipped mode C or mode S transponders which transmit identifying codes and altitude to ATC. They also support systems to avoid collisions. The metal components of a typical Saab key are simple to duplicate, but the microchip that communicates with the immobilizer is difficult to copy. If you have one of these, it's vital to protect it. Everyone with a Saab should have at least two working keys for the car. You'll be required to pay a considerable amount of money when you lose your sole key. You'll need to purchase a special computer module as well as a new key and program the car to convince it you're not trying to steal it. Immobilizers Immobilizers are an additional layer of protection against hotwiring. They stop the engine from being started unless the transponder in the key fob matches. In addition, most cars with immobilizers also display an indicator in the instrument cluster which indicates the key isn't in. If you lose your keyfob, you will need to visit an authorized dealer to deactivate it and purchase a new one. These systems rely on encryption of data between the transponder systems and the vehicle. Recent studies have revealed, however, that encryption sequences can be cracked by computers. Hackers can bypass them by reading the messages that are sent back and forth over the CAN bus. These systems are far more advanced than conventional immobilizers which use a fixed code. Newer versions use a system which rolls or changes codes to increase the security of the system. The issue with these versions is that hackers can still find ways to hack the code, and then use a key to start your car. To solve this problem the DST80 was designed with a longer sequence to make it more difficult to guess. Unfortunately researchers were able to solve this problem as well. Therefore, saab replacement keys uk G28CarKeys to always keep your key fob with you when you're not using it.
