Numerical combination locks have kept our stuff safe for hundreds of years. (Thanks, numerical combination locks!) But why not mix things up a little bit? How about a lock with a cheat code, instead of a passcode?
Doesn’t feel terribly strong. (Not a comment on the lock’s ability to stay closed, but I worry that the little joystick thing might be a bit easy to break off, leaving you with a perma-locked lock.) Shackle is pretty small. Given that the only way to reset its memory is to compress the shackle down twice, the shackle is effectively even smaller than it looks. In practical terms, it’s big enough to fasten a chain, or a trunk, or a gym locker – pretty much anything designed to be padlocked. But anything with a combined diameter of more than about 3/4 on an inch is out.
