I've used Elmers white glue for this for a long time after getting 
unwanted noise with hide glue or Titebond.. It's the only good use I've 
ever found for the stuff. I've never had it make noise, so I don't have 
a fix. I'd start with Teflon powder. What were the key pins lubricated 
with, and what are the odds it transferred to the balance hole before 
you replaced the pins? Maybe spinning a bit of steel wool in the hole 
will break the surface up a bit and give the Teflon something to fill.

I've found this noise a lot in new Yamahas. Skritch on the first 
keystroke, and quiet on subsequent strokes. Let it sit for five minutes, 
and the skritch is back. Easing without lubrication typically worked for 
that.
