Hollow Knight: Silksong – Every Simple Key Location and Locked Door Guide

I still remember the first time I saw the Simple Key in Bone Bottom. Five hundred rosaries for a key felt like a scam. After dozens of hours in Hollow Knight: Silksong, I can tell you it is not. These keys unlock some of the most valuable rooms in Pharloom, from powerful tools to story moments you do not want to miss. There are four Simple Keys in the game. Each one is tied to a specific area, and each one opens a specific door. I will walk you through every location and every lock.
