Im new here just got my first set of pick today. I was trying to pick a 141D Master Lock and was really happy cause I got it open in about 20 min. Then I tried to do it a few more times and I couldnt seem to get it to open again. Well just now I decided to try the key on it, and now the key will not go all the way in. It goes almost all the way in and feels like it get stuck on the last pin. Like the key will not go under the last pin. So Im wondering what I did? I know the key worked before i tried to pick it. Is this a security feature or did I just break the lock? Help would be greatly appreciated.
