How to remove 82-247 from door
Hello,
To replace the 82-247, you'll need to remove both the handle and lock housing cover. The cover is attached to the panel stile with several screws, which are each driven below flush to avert interference with the lock housing cover. Each of these screws must be removed in order to free the housing from the lock stile.
Once they're off, the screws for the mortise should then be exposed. Simply remove the four screws holding the assembly in place, and it should come right out.
To install the new one, just reverse the process. Hopefully, this information helps, but please feel free to reach out if we can be of any further assistance. Thanks for posting!
