latch mechanism broken

We have what looks like a the Atrium 82-400 lockset. Can you tell me if the internals can be replaced or do we have to buy the whole set? The latch mechanism has failed, i.e. if you try to enter from outside it won't engage. But works ok from the inside going out.
Thanks in advance!

If your hardware works okay from the inside, but not from the outside, then I don't think the inside mortise lock is the problem. It might just be the outside handle. A good way to test it out is to remove the inside and outside handles and then try to manually throw the mortise lock from both sides.

I have the same issue, however, I can't disengage the handles. Where could I get a manual to do so? I've tried everything I could think of, but nothing happens when I push into the pinholes in the bottom of both handles. In advance, thanks for any guidance you can provide.

I believe the handles are held on with an Allen wrench type set screw. In the case, where the inside unlocks the door and not the outside, check to see if the Allen screw is loose.
