Hi,
I attempted to alter the functionality of a bathroom door lock by adding an anti lock-out function.
It’s a Legge 900 series Mortice lock, so all it needed was the screw into the existing 9A adapter to enable the anti lock-out function.
Once the screw was in, I tested the latch prior to reinstalling the lock in the door & it seemed to behave as expected - pressing the latch in caused the lock snib adapter to rotate to the unlocked position, indicating all should work once reinstalled.
But reinstalling the lock introduced two issues:
1) Turning the lock snib was difficult & I think resulted in its spindle becoming twisted.
2) Turning the latch handle was VERY hard & once pulled down, caused the latch to become partially stuck inside the lock.
It still kind of works - turning the internal handle does activate the adapter & rotates the lock snib, but it takes three pulls of the handle to allow the external handle to open the door.
Latch partially stuck
Lock position
Unlocked position (requires 3 pulls to unlock outer handle).
So I’m now concerned that I’ve broken the Mortice lock.
Can anyone explain what’s gone wrong here & possibly suggest a solution?
