      Q:Is the deadbolt mechanism F13, F14, F20, or something else?
      by|Sep 30, 2021
      1 Answer
      Answer This Question

      A:  When the deadbolt is unlocked, the lock will be in Passage mode until the deadbolt is engaged using interior thumbturn or exterior key. When the door is ajar, you can enable the Storeroom function by pressing the button on faceplate on edge of door. Storeroom will not allow you to re-enter from the exterior without the key for the deadbolt. Thanks!

              Instructions were lacking. Function is shifty, seems to catch inside the body of the lock on some turns but not all.

              Mortise lock as expected. It was a significant project to modify the existing mortise to fit this lock but I got it installed.
