We sell many handle sets that are nearly identical to yours, in function if not in form, and many of those have key locks. However the problem is with the mortise lock. You have a very particular style that isn't generally compatible with the hardware we sell.

That's not to say that the hardware we sell won't work for you, but I think it'd be best to verify before we go further. I'd like you to remove the handle set from the door and show me a picture of the slot that takes the thumb lever. You don't have to remove the mortise, but it might help. That will tell me for sure if our parts are compatible or not.
