Default remote control keypad conductivity repair

For remote controls that have been properly cleaned out and still
don't work like new, I understand some conductive material needs to be
coated onto the circuit board contacts on the inside of the pad
buttons. Reviewing web discussions of this I wonder if a good approach
may be to mix graphite in silicone glue and lightly coat the surface
of the pad's underside. Anyone tried this or have a thought on it?
Others have used electrically conductive paint (e.g., that purchased
at auto supply stores to reconduct broken rear window defrost
circuits) but that would not seem to be as flexible as silicone glue
with conductive material mixed in it. I did read where someone mixed
finely shredded copper (from pipe) with thinly diluted white glue and
it worked well (but for how long?). It would seem that the latter
approach would be better if silicone glue was used, as it is more
flexible. What ye think?


Rob pairs (or more if same matrix dimensions) of buttons cut from the pad of
some disused zapper that has much the same size and spacing of buttons.


thanks, Jeff. your post was quite helpful (unlike some of the others
here, I won't mention any names ("Phil, Jamie and Angelo" (at least
the latter made an attempt)) will try the window defog preparation
first, then later explore the two articles on making your own . . .
