I installed a new Keyed 'Accent' Schlage Lever today.
This one:
LINK It has a Lever on both sides. One side is keyed, the other side has a 'latch/switch' that you can turn 180 degrees to lock.
So, the way this was APPARENTLY designed, is such that if you are inside, and use the switch to lock from the inside, then the exterior lever does not turn (fine by me), but the interior lever DOES TURN (what the heck?!).
So, if you have not already realized the problem, it is very easy to open a 'locked' door from the interior, walk out, close the door, and get LOCKED OUT!!!
It's the first time I ever see a lock work this way. Normally if you lock from the inside latch, then NEITHER lever (inside or outside) can be turned. This was you KNOW the door is locked and are FORCED to unlock it before exiting.
Is this by design? What was Schlage thinking?!
