Seems like the way to go.

There's an image in the above link that clearly shows how the keyboard action presses onto the contact strip, and it certainly looks less than ideal. It's taken a while to get to here, but the end result should be worth it.

Hey voip! Thanks for all the help
New key contacts - perfect. Turns out the guy did clean the contacts. With deoxit. I think my problems and inconsistencies were due to the fact that only three keys actually worked.
So - isopropyl alcohol only would be my opinion.
