Chest & Door Locks is a security and access-control mod for Minecraft Java that lets you protect chests, doors, storage blocks, machines, and other compatible targets with PIN keypads and programmable Key Fobs.
Built for survival worlds, multiplayer servers, shared bases, and anyone who wants proper access control without turning their base into a redstone project.
Chest & Door Locks can protect:
Place a PinLock on a supported block and configure a 4-digit PIN.
Each PinLock also uses an ordered 3-pane security pattern made from vanilla glass panes.
All 17 vanilla pane types are supported, giving you thousands of possible visual security combinations.
The center pane controls the visible accent color of the lock.
Crafting a PinLock also creates a matching blank Key Fob.
A programmed Key Fob can:
A Multi Key Fob lets one fob control multiple aligned locks that share the same access profile.
This is useful for:
Combine programmed Key Fobs in an anvil to create a Master Key Fob.
Master Fobs can contain multiple access profiles, allowing a single fob to authorize different groups of locks.
You can also merge additional fobs or other Master Fobs into an existing Master Fob.
Duplicate profiles are automatically ignored.
While holding a matching Key Fob:
Remote access works from up to 20 blocks away and always requires you to target the exact keypad you want to control.
Each PinLock can be configured to automatically relock.
You can choose:
Doors and similar blocks will attempt to close before locking and will retry if something blocks them.
PinLocks can be mounted on doors without replacing the vanilla door itself.
The lock remains visually attached to the selected side of the door as it opens and closes.
This works with:
Some blocks support multiple PinLocks.
Examples include:
Every locked PinLock attached to the structure must authorize the player.
Your inventory includes a dedicated Fob Slot button.
Use it to move one Key Fob into PinLock's protected storage.
A fob stored there:
This is the recommended place to store your main or Master Key Fob.
PinLock is designed to avoid losing important access credentials.
The Secure Fob Slot persists through death.
For normal inventory fobs, PinLock can attempt to move them to the player's Ender Chest before a normal death drop. If recovery storage is needed, Lost Fob recovery is also available.
PinLock also respects keepInventory so it does not unnecessarily move or duplicate fobs when inventory is already being preserved.
If a protected storage block is completely empty, PinLock allows controlled reset options without requiring the old PIN.
This helps prevent abandoned locks while still preventing reset from becoming a storage bypass.
No external guide mod is required.
Hold a Key Fob and press:
Shift + M
to open the built-in Field Manual.
The manual includes:
[Glass Pane] [Glass Pane] [Glass Pane]
[Iron Ingot] [Lightning Rod] [Iron Ingot]
[Redstone] [Redstone] [Redstone]The three panes determine the security pattern.
Crafting a PinLock creates:
This release is built and tested specifically for:
Minecraft 1.21.1 + Fabric
Other Minecraft versions should not be assumed compatible unless a dedicated build is released for them.
Chest & Door Locks is especially useful for:
If you want proper PIN-based access control, programmable Key Fobs, remote locking, and secure storage without relying on command blocks or complicated redstone, Chest & Door Locks gives you a complete in-game security system.
