In Hollow Knight: Silksong, there are four Simple Keys in total. They are used to unlock four special doors that grant access to hidden areas and rewards.
Details on each Simple Key
- Location and how to obtain
- Bone Bottom: Purchase from Pebb for 500 Rosaries. This is the quickest way to obtain a Simple Key early on.
* Sinner's Road: Defeat the Roachkeeper at the top of the tower to obtain the key.
* Sands of Karak: Loot a corpse on an eastern bench to recover a Simple Key.
* Songclave: Purchase from Jubilana for 650 Rosaries after completing The Wandering Merchant quest.
- Primary uses (doors they unlock)
- The lower entrance to Wormways from Bone Bottom (to access west Wormways).
* Central Deep Docks, southern area near Forge Daughter (lower Deep Docks).
* The Green Prince’s cell in Sinner’s Road (access to Lost Verdania).
* High Halls, west of the Ventrica station (access to the Rosary Vault).
Common notes
- Each key is a single-use item. Once it opens its corresponding lock, it is consumed.
- Some guides also mention an unused sprite in game files that resembles a Simple Key, but the four keys listed above are the ones implemented for unlocking doors.
If you’d like, I can summarize locations on a quick map-style checklist or list exact coordinates/paths for each door in Pharloom.
