I came across one of these, attempting to let my moms co-worker into her room. Well, actually, my mom needed access, not right away but I suggested that I might as well take a peek, because I was there afterall.
Anyways, I've seen previous posts towards this lock and how some have security pins, so instead of picking, I attempted to slide back the spring bolt. But, to my surprise, the spring bolt wouldn't fully retract. It would move in a little bit, but would stop about half way.
Are these locks designed this way? FalconLock.com doesn't specify. Nor did I try wiggling the door or anything.
