Depends on your keyboard, but most you can gently pry (using a flat
bladed screwdriver) on the underside of the sticky key. It will pop
out, then you can clean the affected area with isopropyl alcohol.

Most sticky keys can be fixed this way. However if your problem was
say a spilled sugary drink (but that usually affects a number of keys,
not just one), the problem could be the sticky substance is between
the membrane and the PCB (printed circuit board). If this is the case,
you have to take the keyboard apart.

This isn't too difficult either, just flip the keyboard over (keys
facing down, and put something along the underside edges of the
keyboard (to keep the keys from actually touching the tabletop, then
unscrew the back off, maybe have to unscrew the PCB, then lift the PCB
out. Just be careful not to knock the front faceplate of the keyboard
off the spacers you put to key the keys off the tabletop, or the keys
(depending on how they are set in there) will come out of the
faceplate, because then you'd get to play "Does the "S" key go on the
left side of the "D" or the right?" <grin> Once the PCB is pulled out,
you can separate the rubber membrane from it and clean both with
Isopropyl alcohol.

While you wouldn't get zapped, it's always a good idea to do this
with the keyboard unplugged. Saves you from getting a bunch of
extraneous keystrokes to the computer as well while you're fiddling
with it.

I've repaired/cleaned many a computer operator's keyboard after they
spilled coffee or soda in it.


Cheers,
Leif Gregory
