I would have to search out a wider pen. Can anyone earlier who was talking about opening a lock with NBA key describe what they did?
Earlier, people were talking about stretching out the bottom of their pen barrel, but I applied a lot of force and twisted clockwise etc and it did expand to fit around the wider cylinder, but I still couldn't get anything to move.
both of my locks, purchased this year, are NBA 5XXX. The vulnerable one was NBA50xx, and the one I couldnt open was NBA51xx. I don't think the series matters as much as the pin heights thogh. I noticed the 51XX had a slightly higher high postion and a far lower low position on the key...in fact the low was so low you could barely see it. That could have made it incredibly hard to pick since one tumbler was very well at teh division line to begin with, and the other had to be pressed completely down.
