What can I lock? By admin | June 13, 2013 - 9:59 pm |June 13, 2013 You can lock chests, doors, trapdoors, fence gates, furnaces, dispensers, and droppers. Why not enderchests? Enderchest contents are per-player, so if you have stuff in an enderchest, someone else will see other stuff in they’re enderchest. Bookmark the permalink.
