ItemLocks Mod (1.21.11, 1.20.1) – Lock Selected Inventory Slots

Alright, so picture this: you're deep in a Minecraft cave, mining away, and you go to quickly drop some cobblestone to make room. In that frantic click, you accidentally toss your favorite enchanted pickaxe right into a lava pool. We've all been there, right? That sinking feeling is the absolute worst. What if you could just... prevent that mistake from ever happening? That’s the brilliant, simple peace of mind offered by the ItemLocks Mod (1.21.11, 1.20.1) – Lock Selected Inventory Slots.

Your Digital Safety Deposit Box

Think of this mod as adding a little padlock to your most precious inventory slots. It’s not about complex new systems or fancy blocks. It’s a pure, straightforward utility mod. Once installed, you can simply choose any slot in your inventory or hotbar—maybe the one holding your diamond sword, your Elytra, or that stack of rare Netherite—and "lock" it. With a simple key press, that item becomes fixed in place. It won't move, drop, or be swapped out by accident. It's just safe.

Freedom to Play Without Fear

This changes your gameplay in such a subtle but powerful way. Suddenly, you can mindlessly clear out junk from your inventory after a long farming session without that nagging worry. You can rapidly shift-click items into chests, and your locked gear stays put. It’s perfect for modpacks where your inventory gets crowded, or for multiplayer servers where a clumsy misclick could be disastrous. It just lets you play more freely and confidently.
