very cool I had no idea it was a puzzle key and lock but I just watched the video on the pictures of it theres a video of a guy doing it, I figured out it's not a pull up one but a circle obviously so just be patient and feel the movement loosen up and bravo 20 minutes and I have it sussed so worth it just try to get into anything its locking good luck they will need it definitely worth it I got 3 more

Nice, relatively simple puzzle. Hasp a little tight but loosens slightly with manipulation.

good puzzle. I still can't figure it out. that must be why they call it a puzzle. he'll! lol!
