Saab Car Key Replacement  
  
Saab key replacement for cars is something that all drivers will have to tackle at some point. Saabs require keys that are special and have chips that identify them.  
  
If you are unable to replace one of them the car won't start unless you have the other. However you can save a lot of cash by buying it yourself instead of paying a dealer.

The owners of the 03-11 SAAB 9-3 have an unique problem when it comes to their car keys. Key fobs like these are prone to breaking easily and are not very durable. Many people don't have an extra, which could be a security risk during an emergency.  
  
You'll have to pay about $400 to the dealer to add an extra key. You'll need an additional key and transponder, plus have the existing one programmed to the car. The dealer will use the Tech-2 tool to execute this process. It is a simple process, but you'll need some mechanical expertise to make the key. It's best to leave this to a professional. The first step is to take the emergency key from the case. Insert a flathead in the slot located in the middle of your key fob. After a little work you will be able of splitting the key.  
  
Remotes  
  
The modern Saab cars do not use traditional keys made of metal to provide security. Instead, they employ an immobilizer system that is based on the recognition of a unique chip that is embedded in each key. This is the reason a particular kind of key is needed to unlock the car and then insert it into the ignition. This is the reason that the Saab owner should always carry a spare.  
  
The traditional metal keys can be copied easily but the issue is that the electronic component of a key-fob must be compatible with a particular vehicle in order for it to function. This is accomplished through the computer modules of the car, referred to as CIM (Column Integration Modul) or TWICE. If you lose your sole working key and you lose it, it will cost the dealer a lot of money to replace these modules and to program a new key.  
  
A local locksmith can reprogram the EEPROM in your car's computer and make you a new key, which can save you up to 50 percent or more than dealers charge! We suggest you contact us as soon as you can if you lose your key. This will allow you to avoid the expense of a dealership.  
  
Transponders  
  
A transponder is an electronic device embedded in a key-fob that transmits a unique, coded signal. It's part of the immobilizer system to prevent thieves from using a stolen key to start your vehicle. The transponder signals that the key emits are detected by the receiver that is located near the ignition. The receiver decodes serial numbers that are generated by the transmission. If the number is in line, the car will begin. Transponder keys are found in the majority of cars built in the last two decades.  
  
They can also be found on airplanes. Air traffic control uses them to identify friendly aircraft using the use of a coded signal called IFF (Identification friend or foe). Certain aircraft are equipped with transponders operating in mode C or PROGRAM S, which transmit the identification codes and altitudes to ATC. They also provide collision avoidance systems.  
  
The metal parts of a standard Saab Key are easy to duplicate. However the microchip that communicates with the immobilizer could be difficult to copy. If you have one of these, it is crucial to ensure its security.  
  
Every Saab owner must have two keys working. You'll have to shell out a significant amount of money should you lose only one key. You will need a new, specialized computer module, as well as the cost of a second key as well as programming to convince the car you aren't trying to take it.  
  
Immobilizers  
  
Immobilizers are a further security measure to prevent thieves from hotwiring your car. They stop the engine from starting unless the transponder inside the key fob matches. Most cars with immobilizers also display a warning icon in the instrument cluster, indicating that the key is not in the. If you lose your keyfob you'll need to go to a dealer to deactivate it and then purchase a new one.  
  
These systems are built on encryption of the information that is sent between the transponder and the car's systems. Recent studies have revealed that encryption sequences can be accessed by computers. Hackers are able to bypass them by analyzing the messages sent back and forth over the CAN bus.  
  
These systems are far higher-tech than the standard immobilizers, which rely on an unchanging code. The newer models feature an option of changing or rolling codes to ensure they are secure. The problem with these codes is that hackers still have the ability to find ways to crack the code and program use keys to start your car. To combat this problem the DST80 was designed with a more lengthy sequence to make it harder to deduce. Researchers were also able solve it. As such, it's important to always keep your key fob with you when you're not using it.
