Hi John,
One test you can do is to type to the punch and see if the punch actually
punches the correct code. If it does, then the code bar in the typing unit
is stuck, not the keyboard. If you can read a paper tape with the correct
codes and they type correctly, then the keyboard is more likely to be the
culprit. You can also measure the signals at the output of the keyboard
without disassembling the whole unit. Taking apart the keyboard is a
_major_ pain.

Thanks to all who have responded so far.. I have tracked the
trouble to code level 5.. I have the parity keyboard with split
shifts and '5' is stuck marking all the time. I put myself to sleep
last night reading the maintenance manual, after lunch I'm gonna
dive into it.
WooHoo!
