Glad to report problem fixed. Best I could do with Greg's advice was hang the fob on lampshade nearly touching the lighted bulb. These modern bulbs don't throw out much heat tho. After a couple hours of that tried again. I think the heat helped some. What helped more was instead of trying to twist the blade of the srewdriver in the slot to pry the fob open, I applied the force straight up (the video does suggest this as an option). When you're prying straight up the plastic in the slot doesn't feel so vulnerable so I pushed quite a bit harder and at least created a crease in the side of the fob that i could get the screwdriver into and finish the job. Now has been reassembled and working ok despite 5 degree temp. Still a lot harder than it needs to be. Am going to try applying some very light coating to the edges of the top and bottom of the fob (bar soap?) before reassembling again.
Thanks again Greg.
