When a Saab key fob is used the car recognizes it and allows it to turn on. However, it is only able to do this if the key fob has an unmodified chip that has been programmed to match it. Otherwise, the car will reject the key and won't start.

It has a visual indicator with a black band that indicates which direction current will flow.

Sanabria states that a number of the tools sold in auto parts stores, like the Autel MaxiIM IM608PRO and IM508 are able to assist customers shopping or DIY customers to program replacement keys and restore immobilizer data.
