I think you are on right track and would try to disconnect battery for a few minutes first to see if it resets.
This should certainly be a Ram/Dodge warranty issue as can't see any way Thor could have messed that up. Mine has to go back to the Dodge dealer because there is a programming error in the PCM for the Key Fob. I am hoping they don't blame that on Thor but is possible I suppose.
