Chest Locker

by Vanderflys

Chest Locker lets a server owner lock a container so that only a player holding a chosen key item can open it.

FabricForgeNeoForgeQuiltServer required, client optionalAll rights reserved1.16.2 – 26.3

What it does

A container is locked by a server datapack, and once locked only the player who holds the key item can open it. The key is a renamed stack of 16 cobblestone, identified by a key name, so the lock works the same in single-player and multiplayer. A function removes the lock from a container when used on it with the given item.

The mod needs operator permission to use its functions. It runs on the server, and clients may install it but do not need it. Chest Locker is published for Fabric, Forge, NeoForge and Quilt, with builds covering 1.16.2 – 26.3, and the license is All rights reserved, so the code is not open source.

Key features

  1. Key-based locking

    A container opens only for a player holding the matching key item, so access stays with that player.

  2. Remover function

    An operator can use a function to strip the lock from a container by clicking it with the key item.

  3. Datapack operation

    The locking runs as a datapack that works in both single-player and multiplayer worlds.
