How to use the Storeroom Key in Elden Ring: Shadow of the Erdtree

The Storeroom Key is an item you’ll find while exploring Belurat in Elden Ring’s Shadow of the Erdtree DLC. When you pick it up, you’ll already be past where you need to use it, so it’s easy to miss the door it unlocks — and the NPC you’ll meet inside.

Our Elden Ring DLC guide will walk you through where to find the Storeroom Key and the Storeroom, and what to do with the NPC inside, Hornsent Grandam.

Storeroom Key location in Elden Ring DLC

You’ll find the Storeroom Key as you explore Belurat. You’ll pick it up after you pass by the Storeroom — it’s near the Small Private Altar Site of Grace.

Where to find the Storeroom Key

Elden Ring Shadow of the Erdtree route around the waterfall

From the Small Private Altar Site of Grace, head north and up the stairs. Take out the Horned Warrior, and then turn left. You’ll be at the top of the waterfall that falls down to the fountain square from earlier in your exploration. Stick to the right (north), to find an alley that leads around to the other side — watch for Shadow Undead as you go.

Take a left at the river, and then head into the building on your right. Climb the ladder to find the Storeroom Key

on a corpse at the top.

How to use the Storeroom Key to meet Hornsent Grandam

Elden Ring Shadow of the Erdtree entrance to the Storeroom

Head back to the Small Private Altar Site of Grace. This time, when you leave, take a left (south) to cross the bridge those annoying casters snipe from.

Elden Ring Shadow of the Erdtree Hornsent Grandam

At the far end, you’ll use the Storeroom Key to unlock a door to meet Hornsent Grandam. There’s nothing to do with her yet, but she’s creatively insulting. Unlock the other door just to have more options — it’s not really a shortcut, but it does give you the drop on the Shadow Undead in that dead end.

She’s got some rewards with you if you keep checking in with her at certain points. We’ll walk you through those steps in our Hornsent Grandam guide.
