LockyLocks
by Sattik03
LockyLocks lets players lock containers with keys, so that only the owner, or someone holding a correctly named key, can open them.
What it does
Locked containers are protected by keys crafted from iron or copper, and each lock type carries its own durability. An iron lock lasts up to 36 Minecraft days, while a copper lock lasts up to 24. The mod uses one key type only, the Iron Key, so every lock works with the same item. A key must match the exact name the lock was given, and the match is case-sensitive, which means a key carrying the right name can open the lock even when it was not made by its owner.
Locked containers cannot be broken by default. A config file option lets server owners turn that protection off, so players can break locked containers. The mod is published for NeoForge only, for 1.21.1. The server and every player need the mod installed. Its license is the MIT License, and the code is not open source in the sense of publishing ongoing development.
Key features
Durable copper and iron locks
Two lock types with different lifetimes protect chests and other containers, with the iron lock lasting longer.
Named keys
A key matches a lock only when its name is identical, down to letter case, to the name the lock was given.
Unbreakable containers by default
Locked containers resist breaking unless the server changes a config option to allow it.
Config-based breaking
A toggle in the config file decides whether players can break locked containers.

Use cases
Protecting shared storage
Players on a multiplayer server can keep items in a chest that only the owner or a named key holder can open.
Who it’s for: Players who want locked storage on NeoForge 1.21.1, and server owners who want to decide whether locked containers can be broken.
How it compares
Locksmith uses a custom license and is not open source, with NeoForge files for 1.21.1 and the same client and server environment as LockyLocks. NightLock is open source under the GNU General Public License v3.0 or later, but it is server required with client optional, so players can join without installing it. Mouse Tweaks x ItemLocks Compat is client-side only, released under the MIT License, and is not open source.
