I can't imagine you can manufacture new keys at a repair price the
customer could tolerate.

There's a guy who shows up at local ham radio swapmeets and sells
radio attachment gizmos.
He has a 3D printer and claims to be willing and able to make custom gizmos.

It ain't quick, but you could digitize the shape of an ideal key set, get a 3D print of
its upper and lower surfaces (actually, just the lower surface is critical, the upper
can be done with hand tools), and mold your own key sheet.
If left-side and right-side match, you can (with care) dupe a left-side sheet,
building molds by (if necessary) bronzing the model item.

It'd be easier to get an off-the-shelf product, but most manufacturers (google on
"elastomer kepad" aren't big on stocked items.

So, are there any similar keypads on any items that have spare-parts departments?
