Patio Door Handle
Thanks for posting. I am afraid we don't have a match for this style handle set. It's just not one we've ever had in supply. Some customers have managed to replace this handle set with 3-15/16" style handle sets like the 82-030, but I can't be certain if it would work for you.
You also might want to see if the mortise lock inside the door is broken and the cause of the issues here. To check this, remove the handle set and try manually throwing the lock with a flathead screwdriver. If it doesn't throw, then the mortise lock will need to be replaced also. We also may not have the mortise lock that you have with this handle set; but you can show us a picture to be safe.
