SimpleLocks

by YuWan030

SimpleLocks lets players fasten chests, barrels and other containers with a Lock item, so that only the owner can open them.

ForgeNeoForgeClient and serverMIT LicenseOpen source1.20.1 – 1.20.6

What it does

A container is locked by holding the Lock item and using it on the block, and the lock is bound to the player who placed it. Shift plus right click binds the lock to a player's own account. Most vanilla containers can be locked, and containers from many other mods are supported as well. Ender Chests cannot be stored or locked.

Unauthorized players are prevented from breaking or opening a locked container. Server admins with permission level 4 bypass these restrictions, and only the owner, or an operator, can break a locked container. Because the lock is enforced on the server, the mod is meant for multiplayer worlds where players share a base.

The mod runs on Forge and NeoForge for Minecraft 1.20.1 – 1.20.6, with six release versions covered. It needs both the server and every player to run it, so the environment is client and server. The code is open source under the MIT License and is published with public links to its source and issue tracker.

Key features

  1. Lock item

    A Lock item is used on a container to fasten it to the player who placed the lock.

  2. Owner-only breaking

    Only the owner can break a locked container, which stops other players from taking items from a shared base.

  3. Shift and right click binding

    Shift plus right click binds a lock to a player, so a container can be shared with a chosen account.

  4. Admin bypass

    Permission level 4 admins are not restricted by locks, which keeps moderation possible on a server.

Use cases

Who it’s for: Players and server owners who run Forge or NeoForge multiplayer worlds and want locked storage without a separate permission system. Single-player players who never share containers have little use for it.
