silksong simple key locations

The four Simple Keys in Hollow Knight: Silksong are located in the following places:

1. Bone Bottom — Purchase from Pebb for 500 Rosaries.
2. Sinner's Road — Defeat the Roachkeeper at the top of the tower.
3. Sands of Karak — Loot from a corpse on the eastern bench.
4. Songclave — Purchase from Jubilana in Songclave after completing The Wandering Merchant quest for 650 Rosaries.

These Simple Keys can be used at these locked door locations:

• Bone Bottom — Opens a door that creates a shortcut through the Wormways to the Chapel of the Wanderer.
• Deep Docks — Opens a shortcut door to Far Fields to acquire Flintslate.
• Sinner's Road — Opens the locked door imprisoning the Green Prince to start his questline.
• High Halls — Opens a rosary vault containing rosary chests, strings, and a Rosary Cannon.

Each key can open any of these locked doors, so obtaining all four Simple Keys unlocks these valuable shortcuts and loot areas across Pharloom.
