The main difference with a triple bore hole door is your handleset options.
Schlage door does not shut have to use handle.
Insert the end of a door handle tool or small flat head screwdriver into the hole.
Press in on the tool or screwdriver while pulling out on the handle.
That s the metal catch on the door jamb which can move.
Slide the handle off the lockset until it butts up against the key.
What if you have a triple bore hole door.
Assuming it works when unlocked try locking the knob.
Put the two halves of the lock together on the counter not in the door yet and check if both of the knobs will turn when it is unlocked.
Look for a small hole in the side of the handle near the face of the lockset.
This is because the issue is not with the door and not even with the control the knob has over the stuck latch.
Jammed latch the issue a door latch stuck due to a jamming latch will have no real variation between how the latch moves when it is pressed in or when the handle is turned both when the door is open and when it is shut.
All the same benefits as above apply.
Like the other door setups your deadbolt can be mechanical electronic or smart.
When the doorknob doesn t latch completely and the door won t stay closed the fault usually isn t with the knob but with the strike plate.
