If you can't tease the switch apart to clean up the inside, I can send
you one.
I got a set of 5 from ebay a couple years ago but only used one.
There is a guy selling them right now too, but only in sets of 20 for $40
https://ebay.com/itm/196074860932
Actually, if you send me your bad switch I bet I can repair it with my
bad switch, because on mine the contacts work fine, the stem is broken
so it can't hold a keycap. If your step is good, then together that's a
working switch.
Kinda silly to repair a single keyswitch but, but aren't we all kinda silly?
I don't remember where I got the keycap puller, maybe came in an ifixit
kit? Maybe from a local microcenter?
The keycap puller is this one. It was nothing special when I got it, but
now it's more useful than most, because today most pullers have the
other end has another kind of grabber to pull the switch out of modern
mechanical keyboards that have removable switches, which is no use on
anything old or soldered. While this one the back end of the handle is a
thin flat spudger which is useful.

I had to search to find:

the K key."
What was anyone supposed to do with that?
What I said below and the video wouldn't help with a 100. It only
applies to a 102.
100 has a totally different kind of keyswitch, and no similar easy
possible fix to try, other than just wash the switch with distilled
water (to clean out possible sugars from drinks), then alcohol (to dry
the water), then deoxit (to refresh the actual copper contacts inside),
and actuate the switch a bunch of times (after the deoxit soaks a
while,
you also need a little mechanical action to actually scrub away the
oxidized surface).
If simply washing and deoxit doesn't make it work, then you have to
look
for corroded traces, loose solder joints, desolder and disassemble the
keyswitch itself, maybe replace from ebay (the switches are available
sometimes).
