Saab Car Key Replacement Saab key replacement for cars is a problem that all drivers will have to tackle in the near future. Unlike many other cars, Saabs need special keys that contain a chip to identify them. If you lose either of these, you'll be capable of starting your car until you've got the second.

This is why it's better to leave the task to experts. The first step is to remove the emergency key from its case. This can be done by inserting a flathead screwdriver into the slot that is located in the middle of the key fob. After a bit of work, you will be able to split the key. Remotes Modern Saab vehicles don't use keys made of metal to secure their vehicles. Instead, they employ an immobilizer device that is built on recognition of the key and a specific chip embedded into every key. This is why a certain kind of key is required to unlock the car and then insert it into the ignition. This is one of the main reasons for a responsible Saab owner to always keep a spare key handy. The traditional metal keys can be easily copied but the issue is that the electronic part of a key-fob has to be matched to a specific vehicle in order to function. This process is carried out within the car's computer modules that are known as CIM (Column Integration Module) or TWICE (Theft Warning Integrated Central Electronics). If you lose your only functioning key in the process, it will cost your dealer a significant amount to replace these modules as well as to program the new key. Local locksmiths can modify the EEPROM chip inside your car's computer to create an entirely new key. This can help you save up to 50% of the cost dealers charge.

Transponders A transponder, or electronic chip, is a small electronic chip that is incorporated inside the key fob. It transmits an individual coded message. It's part of the immobilizer to prevent thieves from using a stolen car key to start the vehicle. The transponder signal from the key are detected 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. Transponder keys can be found in the majority of cars built in the last two decades. They are also used in aircrafts. Air traffic control utilizes them to identify friendly aircraft using the use of a coded signal known as IFF (Identification Friends or Foe). Certain aircrafts have mode C or mode S transponders that transmit the identifying codes and altitude information to ATC. They also provide collision avoidance systems. The metal parts of the standard Saab Key are simple to duplicate. However the microchip that communicates with an immobilizer could be difficult to copy. It is essential to keep these safe when you own one. Every Saab owner must have two keys working. You'll have to pay a lot of money if you lose your only key. You will need to buy a special computer module and a second key and program the car to convince it that you're not trying to steal it. Immobilizers Immobilizers provide an additional layer of protection against hotwiring. They stop the engine from starting without ensuring that the transponder on the key fob is in order. Additionally many cars that have immobilizers are equipped with an indicator in the instrument cluster, which indicates the key isn't in. If you lose your key fob, you'll have to visit an authorized dealer to get it removed from the system and obtain the replacement. These systems are built on encryption of the data that flows between the transponder and the car's system. However, recent studies have found that these encryption codes are too easy for computers to crack. Therefore, they are able to be bypassed by hackers who can understand the messages going back and forward on the CAN bus. These systems are far more sophisticated than traditional immobilizers which use one fixed code. Newer versions use a system which rolls or changes codes to increase the security of the system. The problem with these is that hackers still have the ability to discover ways to break the code and then use keys to start your vehicle. In an effort to solve this issue, the DST80 was developed with a longer sequence to make it more difficult to guess. Researchers also managed to crack it. It is important to keep your keyfob in your pocket even when you're not in use.
