Key - Lock chests, other containers and doors
by CMD-Golem
With Key, a container, door or trapdoor is locked to the player who placed the lock, and only that player can open it again.
What it does
Key locks chests, other containers, doors, trapdoors, fence gates and blocks from other mods, so items stay protected from other players and from Creepers. A locked block is tied to the player who locked it, not to a physical key item, so the lock holds until that player removes it. A hologram shows the lock owner, and a locked container cannot be broken by others.
The mod suits survival worlds and multiplayer servers where players share a base. Server owners can cap how many blocks each player may lock, both per player and for the whole world, and the mod provides an admin key for overriding locks. Locked furnaces and similar blocks keep their processing and fuel use, while hoppers placed underneath a locked container cannot pull items from it.
Key is published for Fabric, Forge, NeoForge and Quilt, and a data pack version exists too. Server owners install it, while players can join without it, since the environment is server required and client optional. Files cover 1.20.2 – 26.3 with 22 release versions, and the code is covered by a custom license that is not open source.
Key features
Locking containers and doors
Chests, other containers, doors, trapdoors and fence gates can be locked by the player who places the lock.
Owner-based access
Access depends on the player who created the lock, and the key item itself is not needed to open it.
Keys with durability
Keys wear down with use, can be enchanted with Unbreaking and Mending, and can be repaired at an anvil with a gold ingot.
Configurable limits
Server owners set a cap on locked blocks for each player and for the whole world through a settings menu or commands.
