simple key locations hollow knight

Here are all the Simple Key locations in Hollow Knight, plus what they unlock, in a quick, spoiler‑light format.

How many Simple Keys?

  • There are 4 Simple Keys total in Hollow Knight.
  • You only need one to progress (for Royal Waterways), but the others unlock optional areas and content.

Simple Key locations

  • Key 1 – Sly’s Shop (Dirtmouth)
    • Buy from Sly in Dirtmouth after you rescue him in Forgotten Crossroads.
* Costs **950 Geo** once he’s back in his shop under his house.
  • Key 2 – City of Tears (City Storerooms area)
    • From the City Storerooms stag station, head down into the big vertical room with hanging platforms and Winged Sentries, then go as far right and high as you can to a side room.
* The key is in the **top‑right alcove** of that room.
  • Key 3 – Ancient Basin (Mawlurk corpse)
    • Go to the lowest part of Ancient Basin , in the area with Mawlurks that spit goop.
* Walk into the big **Mawlurk corpse** on the right side; inside is a dead Royal Retainer holding a Simple Key.
  • Key 4 – Colosseum of Fools (Pale Lurker)
    • Start at the Colosseum of Fools bench, then go right, up into the arena area, and break a hidden wall on the right to reach a secret zone.
* Drop down into the water, go right, and chase the **Pale Lurker** , a fast enemy dropping spike traps; defeating it gives the last Simple Key.

Where Simple Keys are used

  • Confessor Jiji’s House (Dirtmouth)
    • Far right side of Dirtmouth , past the well, is a locked door to Jiji’s house; use one Simple Key.
* Jiji lets you **summon your Shade** there instead of going back to where you died.
  • Royal Waterways entrance (City of Tears)
    • In City of Tears , a floor grate a bit left of the Pleasure House is locked and needs a Simple Key.
* This opens the **Royal Waterways** , which you’ll want for items like Isma’s Tear and late‑game areas.
  • Pleasure House bath (City of Tears)
    • Also in City of Tears, a locked door near King’s Station leads to a hot spring and NPC in the Pleasure House.
* Good for restoring Soul and picking up some extra lore and rewards.
  • Junk Pit / Godseeker (Royal Waterways)
    • Deep in the Royal Waterways , in the top‑left of a maze‑like area full of worms, there’s a locked sarcophagus in the Junk Pit.
* Using a Simple Key starts the **Godseeker / Godhome** boss‑rush DLC content.
