Here's How To Find All Of Hollow Knight's Simple Keys

"Hollow Knight" is a beautiful and atmospheric 2D side-scrolling action adventure game. It's easily one of the best games to play while you wait for "Metroid Prime 4." The highly anticipated sequel, "Hollow Knight: Silksong," is getting closer everyday as well, but there's still plenty to do in the original. 

There's so much to find while exploring the sprawling underground insect city known as Hallownest. Every new cavern seems to reveal new enemies to fight, NPCs to talk to, and items to find. It can actually be a little overwhelming. Sometimes you find a door and you just want to know what's behind it, without having to search through every last nook and cranny for the key.

There are four locations in Hallownest that are barred by Simple Locks and can only be accessed with items known as Simple Keys. The locks are located at the entrance to Royal Waterways from the City of Tears, the cave past Dirtmouth (beyond the graveyard), the Pleasure House in the City of Tears, and the cocoon of the Godseeker in the Junk Pit. Here's where to find them.

Simple Keys are hard to find, but not impossible

The first Simple Key in "Hollow Knight" is the easiest to find, but it doesn't come cheap. You get it by purchasing it from Sly's shop in Dirtmouth (the very first town you come to in the game.) The former Great Nail Sage drives a hard bargain though, and will only sell you the key for a whopping 950 Geo.

You can find the second key in the capitol of Hallownest, the City of Tears. There is a large room with winged sentries and a whispering root which can be found below the City Storerooms. You find the key by going to the highest alcove, way up on the right side of the room.

The third Simple Key can be found in the Ancient Basin, which is located below the Royal Waterways. It's hidden away inside the husk of a dead insect covered in eyes and spikes known as a Mawlurk.

As noted by Kotaku, the last key is only available as part of the game's free "Godmaster" expansion. You get it by killing the Pale Lurker enemy who is hiding behind the Colosseum of Fools. Finding the Lurker on your own can be tricky, but the fight itself is nowhere near being one of the hardest bosses in "Hollow Knight."
