Lookkey
Lookkey gives doors a realistic key lock: players craft keys, bind them to a door and use them to lock or open it.
What it does
Lookkey is a key-and-lock system for doors. Each key is bound to a specific door, so a lock only responds to the key that was made for it. Keys come in four types: Blank Key, Worn Key, Iron Key and Master Key, and the Master Key is the one that opens locked doors. Keys lose durability with use and eventually break, and locking and opening play sound effects. Doors from most vanilla and modded door sets are supported.
Locks work in singleplayer and in multiplayer. Both sides need the mod, because the lock state and key checks run on the server and the client shows the result. A dedicated Lookkey creative tab groups the keys and related items. Lookkey is built for Forge 1.20.1 and is not open source; it is released under All rights reserved. The latest file, Lookkey1.0, was published on 2026-07-01.
Key features
Door locking
Players lock and open doors with keys, so access to a building depends on the key a player carries.
Key-to-door binding
Each key is tied to one door, so a single key does not open every lock in a base.
Four key types
Blank, Worn, Iron and Master keys form a progression, with the Master Key able to open locked doors.
Key durability and breaking
Keys wear down with each use and break when their durability runs out, which adds a cost to frequent access.
Lock sounds
Locking and opening doors play sound effects, so state changes are audible nearby.

Use cases
Secured houses and bases
Players who build homes or bases give out keys so that only chosen people can enter.
Who it’s for: Players who want locks on their buildings in survival or adventure worlds, and server owners who run shared bases where access should be limited.
How it compares
Way Too Many Locks is a Forge mod for 1.20.1 that is also client and server, and it is not open source under All rights reserved, so it covers the same version and environment. Unlock The End is a Fabric, Forge, NeoForge and Quilt mod for 1.21.1 – 1.21.11 that is server required with client optional, and it is likewise not open source. Lookkey differs by being Forge-only and limited to 1.20.1.
