1sweetride, Thanks for all that info. It is all helpful!
When starting the car there is a chip in the Fob that communicates with the SKREEM ( located behind the Instrument Cluster (IC). The ring around the stater switch where the key is inserted is the antenna:


It must be able to communicate with the SKREEM for the car to start.
SO Question; could you have disconnected either of those wires going to the SKREEM having been back behind the IC lately?
Have you replaced the FOB covers, or replaced the FOB batteries ? Some people have replaced the FOB case and in the process dislodged the "chip" that does the comms and you end up with a non start.
Trying to go thru all the possibilities before taking a guess you have a SKREEM problem. Ref post number #8 Without a good scan from something like the DRB III we are all doing a lot of troubleshooting / guessing.
