This chip contains an unique code that is inserted into the car’s computer in order to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. However, it will only do this if the key fob is equipped with a chip that is not modified that has been programmed to match the original. If not, the car will refuse to accept the key and will not start.

Jump-starting the battery
