I am still new so am experimenting with different ways of opening locks. I have a Kwikset deadbolt and a Master No. 3 because I have heard that these are very easy to open...and they are. So I've been practicing with these two locks and have run into the situation where I can open one of the locks in the same manner 4 or 5 times in a row, and then all of a sudden I can't. It seems like I'm doing the same things, but the lock won't open. Then all of a sudden when I think I've bungled it beyond all hope..."CLICK" it opens.
Anyone else experience this as a newbie?
