I pulled a remote out of a drawer that hasn't been used in a long
time. The 1 key doesn't seem to work. Pushing 1-9 causes a light on
the remote to flash, but 1 doesn't flash.
I opened it up and blew on it. It is still broke. :)
s24 is the "switch" behind the 1 key and it looks as good as all the
rest. I am guessing something else has failed.
All the buttons seem to be just a piece of black plastic that touches
I should have turned the flash off, but you can still make out what
the circuit board looks like.

The black button material on the end of each key is conductive, it
bridges the two printed patterns on the printed wiring board when you
press the key. Have you tried interchanging a good key with the bad
one to see if the conductive material on the end of the key has worn
off from use or is dirty?. I have fixed several remotes by cleaning
off the dirt that was on the surface of the PWB and on the surface of
the key, which kept the key from electrically bridging the two
intermingled fingers on the pwb.
+1 on that. I love this stuff from Radio shack.

Expensive-- but worth the price of a can the first time it save an
electronic gadget. I bought my first can to fix a tuning knob on
the TV wee were playing Atari games with. I just bought my second
can last year.
It eats corrosion, gum, gook on any electrical contact. I've cleaned
up remotes, cables of all descriptions, MP3 players, phones. . . .
You beat me to it.
Deoxit is a great product. I can't see it eating corrosion, but otherwise
it's a good cleaner and protectant.
Again, CRC 2-26 available at the home depot, among others is a great
contact enhancer, but does leave some light lube.
MCM electronics, among others used to sell kits to refurbish remote pads.

You probably need to remove the rubbery membrane and clean both its
black circular contacts and the circuit board beneath it with alcohol.
Some of those contacts were lubricated at the factory with silicone
oil, and sometimes the oil evaporates, leaving behind only the thick
greasy part. It's possible that you need to reapply some new silicone
spray, but sometimes that makes the buttons work a lot worse.

After the first time I put it back together, I tried all of the
buttons and a couple of other buttons didn't work either. Two were
labeled macro, so it may be a single push wouldn't cause them to
light. But there was at least one other button that should have light
I cleaned all of the contact points (alcohol and a coffee filter)
giving extra time to the 1 key. When I tried again, the 1 key still
did not work.
I was going to use it so I could add a TV to the HD box. I also have
a set of pyramids so you can be in another room and change the channel
in the main room.
The universal remote is so old that it didn't even have Motorola on
the code list. While I may have been able to get it to work anyway, 1
button being broke was enough reason to toss it.
First clean the pad and contact.
If that fails, slice off a comparably sized pad from a trashed remote and
crazy glue to the failed pad. You may need to practice until you get a
suitably thin slice.
Can you recruit a helper? Kid from the neighborhood?
You need a 11 or 12 year old boy, who has nimble
fingers. They used to use child labor for such reasons,
now days you can do it unofficially for small tasks.

I take meds that make my hands shake. Trying to do
that would be torture for me. :) Glue with anything everything stuck to everything.
