Lucky's Locksmith
by LuckyOwl
Lucky's Locksmith, a NeoForge mod for 1.21.1, lets players lock chests and barrels with keys, so only a holder of the matching key can open them.
What it does
The mod adds more ways to store and lock up items, aimed at survival worlds where players want another layer of security around their belongings. A locked chest opens only for a player who holds the correct key, either in a hand or equipped in a Curio slot. Keys are crafted, and locks can also be placed on chests in certain structures.
Dungeon and structure builders can add locks to chests in their own creations, and multiplayer servers can use locked storage to keep other players out of shared containers. Golden Trial Locks are the only lock type in the current release. Both developer items are found in the Operator Utilities creative tab and are meant for world builders, not regular survival play.
The mod needs NeoForge and is built for 1.21.1 only. Servers that run it need every player to install it too. The files are not open source, and the license is All rights reserved. Source code and an issue tracker are public.
Key features
Craftable keys
Keys are crafted and paired with locks, so a player decides which chests a given key can open.
Locked chests and barrels
Chests and barrels accept a lock and open only for a player who holds the matching key.
Curio key slot
A key can be carried in a Curio slot as well as a hand, so it stays available without taking up space.
