If you’re exploring Hollow Knight: Silksong, you’ll come across Simple Keys, small but very useful items that let you open locked doors scattered throughout the world. These doors often hide shortcuts, valuable treasures, or even important questlines, so it’s worth tracking down every key you can find. In this guide, we’ll cover all 4 Simple Key locations and show you where to use them.
All 4 Simple Key Locations in Hollow Knight Silksong
Simple Keys are handy items you’ll need to open certain locked doors and shortcuts throughout the game. Here’s where you can get them:
Buy from Pebb in Bone Bottom


Head over to Bone Bottom and talk to Pebb. He sells you a Simple Key for 500 Rosaries. Easy and straightforward.
Find One in Sinner’s Road


Another Simple Key can be picked up in Sinner’s Road. Make your way to the tower in the top-right corner of the biome. Defeat the enemy inside, and the key will be yours.
Sands of Karak


In the Sands of Karak, a Simple Key is also waiting. Look for the lone bench here; it’s hidden in the biome’s far-right corner. The key is held by a corpse that is sitting on it. To get there more quickly if you arrive through the Grand Gate, go north rather than through the Blasted Steps.
Buy from Jubilana in Songclave


Later in your playthrough, when you reach Songclave, seek out Jubilana. She’s right next to the Wishwell, so she’s hard to miss. She’ll sell you a Simple Key for 650 Rosaries.
Where To Use Them in Hollow Knight Silksong
Simple Keys aren’t just for collecting, they open up shortcuts, treasures, and even new questlines. Here’s where you can use them:
Bone Bottom


There’s a locked door in Bone Bottom that connects to the Wormways, giving you a shortcut down to the Chapel of the Wanderer.
- To get there, take the elevator from Mosshome into Bone Bottom.
- From here, head up and left.
- You’ll need to jump and dash across the cages hanging over the gap, while dodging the flies.
- Continue to the left and run past the mole to the closed door.
Deep Docks


In Deep Docks, a Simple Key opens a locked door that gives you a shortcut to the Far Fields and also rewards you with Flintslate.
- Start from the bench near the Forge Daughter.
- Instead of going up, ride the switch platforms down into the lower levels.
- Head right and use Hornet’s Dash skill to leap across the lava until you land on the far platform with the door.
Sinner’s Road


One of the most important uses of a Simple Key is in Sinner’s Road.
- Here, you’ll find a locked door that holds the Green Prince captive.
- Unlocking it will kick off his entire questline.
High Halls


In High Halls, a Simple Key opens a locked door that hides a rosary vault. A great way to stock up on currency if you’re running low.
