ItemLocks Mod is a client-side inventory utility mod that lets you lock individual item slots so your tools and gear stay where you put them for Minecraft Fabric, Forge, and NeoForge.
ItemLocks solves a very specific but very real Minecraft problem: losing the wrong item at the wrong time because your hands moved faster than your brain. With more than 1 million downloads, it has clearly found an audience among players who want a safer inventory workflow without changing how the game feels.
Key Features of ItemLocks Mod
- Lock individual slots on demand — Hold the lock key, then left click a slot to protect it from accidental movement. That makes it easy to secure your sword, pickaxe, ender pearls, or any other item you do not want to misplace during combat or routine inventory cleanup.
- Bypass locks when you intentionally need to move items — The bypass key lets you interact with a locked slot without permanently disabling it. This is the right balance between safety and flexibility, because you can still reorganize your inventory when you mean to, instead of fighting your own protection system.
- Locks save separately per world or server — Your locked slots do not bleed across every place you play. That matters if you use different hotbar setups for survival, PvP, or a modded server, because each environment can keep its own layout without extra setup.
- Configurable controls and settings — ItemLocks can be adjusted through the Mod List or by opening its options menu. If the default keys are not comfortable, you can tune the experience to match your setup instead of forcing yourself to adapt to one preset.
- Locked slots stay locked even when emptied with bypass — If you intentionally clear a locked slot while bypassing, the lock remains in place. That is a useful detail for players who want the protection to survive brief item swaps, so the slot is ready to be reused safely later.
- Empty locked slots activate when filled — A locked empty slot does not behave like a normal occupied slot until something is placed there. In practice, that keeps the system from getting in your way while still preserving the lock state for future use.
- Client-side protection with clear limits — The mod helps with actions your client can control, but it does not claim to protect you from death-related item loss or server-side inventory changes. That honesty is useful, because it sets the right expectations before you rely on it in a world or server.

Frequently Asked Questions
What does ItemLocks Mod actually do?
It locks inventory slots so items are harder to move by accident. That makes it useful for keeping a weapon, tool, or other important item in place when you are looting, fighting, or reorganizing quickly.
Is ItemLocks Mod client-side?
Yes — the mod is client-side only. It can protect you from your own accidental inputs, but it cannot stop death item loss or any server-side manipulation of your inventory.
Can I use ItemLocks on Fabric, Forge, and NeoForge?
Yes — the mod supports Fabric, Forge, and NeoForge. That gives it a wide installation range across the major mod loader ecosystems listed for this release.
Does ItemLocks save locks separately for each world or server?
Yes — locks are stored separately per world or server. That is helpful if you use different hotbars or loadouts in different places, because you do not need to reconfigure everything manually each time.
Can I lock an empty slot?
No — empty slots cannot currently be locked. The mod notes that this may become configurable in the future, but for now a slot needs an item before the lock behavior applies.
What happens if I empty a locked slot while bypassing?
The lock stays in place. That means the slot can be cleared temporarily without losing its protected state, which is useful if you are swapping items on purpose.
How do I change the keys for locking and bypassing?
You can change them through the Mod List or the mod's options screen. The default bindings are C for lock and B for bypass, but the mod is meant to be configurable to your preference.
