Nothing. As I said, we never fixed them. I have put wires on CPU

Dead chip in the keyboard, usually. We never fixed them when I used
VT100s on a daily basis.
Do you know anything about the type/location on the board of this chip? Hmm.. VT100 keyboard schematics, anyone? :) I'd
really like to make this
into a console for my PDP-11.
Never seen keyboard schematics. I have some manuals for some of the
terminals, but I don't recall that the keyboards are really mentioned.
I know it's not what you want to hear, but they really were disposable.
Expensive, but disposable. I think people might have swapped switches
if they were physically broken (keystems snapping off or the leaves in
the switches getting bent from vigorous keytop insertion), but I do not
have a single memory of anyone attempting electronic repair 20 years ago.
