Your mortise latch needs to be activated by pushing in that center activator. That will let the locking hooks come out of the door. Try pushing that activator to see if the mortise lock will operate. If it does then the problem could be in the strike plate in the door jamb. Take a look at our 89-042 to see if it's a match. If it does, then consider the 89-043 strike plate cover. However if your mortise latch does not operate when you depress the activator then you will need to replace it with the 82-238. To remove your handle you will need to remove the square screw hole covers in the inside handle to access the mounting screws. You can use a small flat blade screw driver to pry off the covers. |

The only square cover we sell in relation to the hardware discussed here is our 89-043, though this is for the keeper, not the mortise. If that is not what you were referring to then we will require photos in order to verify if it's something we can supply. |
