Chest Locker
by areedelahi
Chest Locker lets players lock a chest so that only the owner can open it, and it blocks hoppers, dispensers and other automation from pulling items out.
What it does
A locked chest refuses to open for anyone else, including hoppers and dispensers, which keeps stored items from being taken by automated systems. Locking works in a simple way: a golden nugget renamed to Locker is used on a chest to attach the lock, and the chest then stays protected. Admins can use the same renamed nugget to open a locked chest and view its contents for security checks.
Locked chests also gain extra resistance to explosions, so they are harder to destroy than an ordinary chest. The mod keeps the vanilla style of the chest and adds only a small amount of visual detail to mark a locked one. Lithium, a common optimisation mod, is supported and does not break the hopper blocking behaviour. Chest Locker requires Areed's CoreLib, and it is published for Fabric only.
Server owners install it, and players connect with no copy of their own. Files cover 26.2 and 26.3, with 1.1.3 for 26.3 as the latest build, first published on 2026-06-24 and updated on 2026-09-16. The license is All rights reserved, so the code is not open source.
Key features
Hopper and dispenser protection
A locked chest will not open for hoppers, dispensers or other automated blocks, so its items stay where the owner left them.
Golden nugget locker
After installing the mod, a golden nugget renamed to Locker is used to lock or toggle a chest in a single step.
Admin view
Admins can use the renamed golden nugget to open any locked chest and view its contents for security checks.
Blast resistant chests
Locked chests gain extra resistance to explosions, making them harder to destroy than a plain chest.
