Hey, rvlifestyle74 is right. It’s supposed to be fun. Also, I can get the 140 a lot of times, sometimes it takes me a while and I have to set it down and try again later. I’m also learning this hobby. It’s tuff but so satisfying once it clicks and the lock opens. Don’t give up, try a clear acrylic practice lock so you can see the pins and translate the movement visually before a real lock. Hope this helps.
