Bound House Key
By editname
House Key adds a craftable House Key item that binds to the first player who right-clicks it and lets that owner lock and unlock doors so only their key can open them. Right-click a door with your bound key to lock it to that key, and sneak-right-click with the matching key to remove the lock; locked doors ignore normal interaction, empty hands, wrong keys, and other players' keys. Keys store their owner on the item stack, door lock ownership is saved with the world (and cleaned up when a locked door is broken), and the item includes a creative tab entry, texture, recipe, and in-game tooltips explaining usage.
