PCM (vehicles computer) is not recognizing RFID ..chip in key. Do you have an original KEY(s)or have they been lost? programming a FOB is one issue not to difficult, but without the original correct RFID key that's trouble! DEALERS like approx $90 for the FOB and another for $115 "programing" ... I do this with the right electronic gear 5-8 minutes. I suggest trying to locate a local CAN BUS guy that knows what up, to assist you call around. Regards '03 SAAB likes the (Old GM Tech 2) for computer work

Dealer said $1000... shameful! The original FOB is where I would begin.. so it lost then recovered ...next you bought a cover and battery and changed (replaced) this "out" and now the immobilizer doesn't recognized it correct?

Is the ignition cylinder stuck in the down position, making the car think there is a key in it? If you're getting error on the key, look at the circular antenna there around the ignition key and the connections between that and the TWICE unit.....SAAB calls there immobilizer system a "TWICE" does the key FOB lock or control any function now? The immobilizer communicates with the RFID tag in the key and sends the key's ID to the TWICE module. The TWICE compares the key's ID to the one that its programmed for. It then sends a "Key accepted" signal to the car's BUS. The TWICE also interprets the ID of the remote control used. SEE Ignition photo ...

The only "ring" that has any wires going to it is part of the cover. There is also a remote control receiver located in the console. The TWICE module is under the drivers seat.
