Yup! The shift keys, enter, and backspace can be rather troublesome. A
good first troubleshooting step is to check if you have some broken
rivets in that area, which is very likely considering the age. If that's
not the case, pop the key out and look at the chimney area where the
spring sits inside of the key. If there's some sharp edges you can
lightly file them inwards. I usually clean the stabilizers with a q-tip
and then spray some PTFE dri-film lubricant onto another q-tip and apply
inside the stabilizer as well as the key's stabilizer "post". I've had
really good luck so far with un-sticking keys, so I hope this helps!
Also, I'm curious as to what kind of 'dry' lubricant you are using?
(...and cleaning 'em up surely is gratifying! :D)

Have you encountered any problems with the r/h shift
key? Mine has a
habit of sticking if it's pressed in the r/h 20% or so of the key
width, and I assume from new they were designed so they they could be
hit at any spot; obviously it seems to pivot a little and then jam. I
assume it's worn somewhere, although there aren't any visible signs of
where it binds. A bit of 'dry' lubricant a couple of times a year
helps a lot, but isn't enough to cure it entirely (and most of the
time I'm not hitting the key in that last 20% anyway, but once in a
while it'll catch me out).
I could probably use another M (maybe even two) at some point, and
also a model F. But cleaning them up is part of the fun... :-)
