Before you do...

These switches don't wear out of too much use, but get a little
non-conductive oxide on their contacts caused by using to less!!!

So try the following - as someone else suggested somewhere, sometime:

"Hammer" those offending keys (with you your fingertips), and eventually
they came to life!
In the past all my 5 desoldered keyswitches from the Master128 are
actually still (electrical) ok!
