This can be done by inserting a flathead screwdriver into the slot in the middle of the key fob. After a bit of work, you will be able of splitting the key. Remotes Modern Saab vehicles don't use keys made of metal to lock their cars. Instead, they employ an immobilizer system based upon the recognition of a special chip built into every key. This is why a specific type of key is needed to unlock the car and insert it into the ignition. It is for this reason that the Saab owner should always carry a spare. The classic metal keys are easy to duplicate however the issue is that the electronic portion of a key-fob has to be connected to a specific car in order for the key to work. This process is carried out in the car's computer modules that are known as CIM (Column Integration Module) or TWICE (Theft Warning Integrated Central Electronics).

Transponders A transponder or electronic chip, is a tiny electronic chip that is placed inside the key fob. It transmits an individual coded message. replacement saab 9-3 key 's a component of the immobilizer to prevent thieves from using a stolen vehicle key to start the car. The transponder signals are received by a device close to the ignition, which determines the serial number from the transmission. If the numbers match, the car starts. The majority of cars built during the last two decades use transponder keys. They are also used on airplanes. Air traffic control uses these to identify friendly aircraft by using an encoded signal called IFF (Identification friend or foe). Some airplanes are equipped with mode C or mode S transponders that transmit the identifying codes and altitude to ATC. They also include systems to avoid collisions. The metal parts of a standard Saab key are easy to duplicate, however the microchip that is connected to the immobilizer is hard to duplicate.

This means that they can easily be bypassed by hackers who are able to detect the messages that travel back and back on the CAN bus. These systems are far more sophisticated than conventional immobilizers, which use one fixed code. The latest models have the capability of changing or rolling codes to make them more secure. The issue with these is that hackers are still able to find ways to crack the code and use the key to start your car. To solve this problem, the DST80 has a longer code to make it harder to figure out. Unfortunately researchers were able to break this too. It's essential to keep your keyfob with you even when you're not in use.
