One additional thought.
When we lived in the Forest Service cabin, more of a shack with tar paper exterior, we had no locks. We had little anyone would take and any neighbor looked out for one another. Although Bears liked the 'root cellar'... a strong door with a couple of 2x4's to secure them did the trick.
Hunted with a Remington 22 rifle for rabbit at 6 years old. Snow rabbits at 7. ...and no, I did not shoot myself or get lost. This was our Costco shopping in the deep forest, kind of thing. I still own the rifle.
