UPDATE*

Aloha my fellow Crossies!
I spent some time messing with Xfire as it was a slow day.
I started the car.
I replaced the fuse. Alarm went off and key fob would not shut off alarm or lock/unlock doors.
I pulled #9 fuse again.
I turned of the car.
I replaced the fuse in #9. Alarm went off, but I re-tried key fob. It shut off alarm and doors locked!!!

This may have reset the SKREEM, etc.

Anyhow it now works. Start stop panic lights alarm all work fine. Was perhaps a glitch in its system.

BTW I had tried a new fob and my original fob (best to have a whole nother spare fob)

Thanks for listening and if this helps just one other Crossfire owner I'll be happy!
Saved me taking off the cowl, or the instrument cluster and buying another SKREEM or having mine repaired. Wish me luck that this is solved for now. The SKREEM siren does have a built in battery and you must replace the whole siren/batt combo if that is a problem on your Xfire.
I sent an Email to SOS about the VIN specific issue for the control module. I will relay their info when they respond.
I do believe a good used module from Ebay would solve other associated problems. No way would I pay more than $135 bucks for one, even new with warranty. Don't know why Mopar-Chrysler list two with the same part number and one at $900 and one @ $155. I would buy the $155 as there is no difference I can see except perhaps internal "programming".
These module devices should program themselves, replace unit, reconnect battery, insert key, turn key to #2 wait a minute and then try starting car. If the module (used or new) came from the same exact car with alarm it 'should' be plug and play. We'll see what SOS says.
Till then Aloha!
