Sometimes the troglodyte approach to fixing keyboards

Also, on some types of keyboard, you can get at the contacts just by
pulling off they keycap. I have no idea if any Model 4's used that
type, though. Quite likely not.
You can get at the contacts, but you'll have to desolder the entire switch
first. I desoldered an entire PT210 keyboard, which uses the same
keyswitches, and applied pcb-trace paint to the black rubber part. It
works great now.
