Simple Key

Simple Keys are Items in Hollow Knight. They can be used to open simple locks. Each key can only be used once.

Use
There are four locations that can be opened using Simple Keys:
 * The entrance to Royal Waterways from City of Tears.
 * The cave to the right of Dirtmouth, beyond the graveyard. This cave is home to Confessor Jiji, who, in return for a Rancid Egg, can summon the Knight's Shade, which is useful if the Shade is stuck in a hard-to-access area and holding a lot of Geo. In Steel Soul Mode, the cave is instead home to Steel Soul Jinn, who trades Rancid Eggs from the Knight for Geo.
 * The Pleasure House in City of Tears, along with a Hot Spring, Poggy Thorax, and Songstress Marissa. It is also Millibelle's refuge after she scams the Knight. Once inside, a shortcut can be opened from the Hot Spring to a lift shaft that leads from City of Tears to Resting Grounds, and also grants easy access to the northern part of Kingdom's Edge and the Colosseum of Fools.
 * The cocoon of the Godseeker in the Junk Pit. Using the Dream Nail on her grants access to Godhome.

How to Acquire

 * One can be bought from Sly in Dirtmouth for.
 * One can be found in City of Tears, in the big room with Winged Sentries and a Whispering Root just below the City Storerooms. The key is located in the topmost alcove on the right of the room.
 * One can be found in Ancient Basin, on the dead body of a Royal Retainer inside a Mawlurk corpse.
 * One can be obtained by killing the Pale Lurker in a hidden area behind the Colosseum of Fools.
