Mortal Shell 2 All Key Locations and What They Open

Mortal Shell 2’s world map carries 18 key pickups, all verified on LootMap’s interactive map.

Two Locked Gates and two Vlas’s Cage markers have no key named for them, and the three Locked Chests sit on the chests layer rather than with the doors. Open keys and doors together and one pattern makes the hunt manageable: the Light and Dungeon Keys come in trios, each trio within sight of a lock marker. The three single keys take more walking.

Chapel Key and the Mushroom Village chapel

The Chapel Key sits in the Mushroom Village area of Fainweald, just east of Tiel’s shell pickup. Its description does the guide’s job for it: the key unlocks the chapel doors outside the Mushroom Village. The Chapel Key Door sits northwest of the village, and the Axe & Dagger weapon marker sits on the same spot, so opening the chapel is how you claim one of the seven weapon pickups. If you have circled the village and typed “mushroom village key” into a search bar, this is the door those searches mean.

Crypt Key: found in the west, used in the northeast

The Crypt Key sits in western Fainweald, a few steps north of a Flower Chest and a short walk southwest of the Locked Gate pocket. The in-game description reads “Opens a locked door within a dungeon,” and the door the map pairs with it is nowhere near the pickup: the Crypt Key Door is in Fainweald’s northeast, clear across the region. The northern Dungeon Key trio is strung out just northwest of that door.

Light Keys come in three trios

The nine Light Keys split into three groups of three, and every group has one Locked Chest marker inside or beside it. The map does not record what a Light Key turns, so read the pairing as map layout rather than a tested mechanic, but the layout repeats three times:

• Three keys sit a few steps apart on the far eastern edge of the map, and the Locked Chest between them sits in the middle of the trio. Two Stone Gate markers, a Healing Power Chalice and the Heart of Vatra pickup share the pocket.
• Three more sit in a row along the Mushroom Village’s north side, with a Locked Chest just west of them. The Chapel Key link above lands one screen south of this group.
• The last three sit on the Mammon side, running north from the eastern City Map Station, and the Locked Chest beside the southernmost key is close enough to touch.

One warning before you cross-reference other lists: these are not Blackmarrow Keys. Player reports say there are eight of those, hunted for the Shade cosmetic chests, and the map does not cover that collection. Nothing on the map connects it to the Light Key markers, so treat them as separate lists.

Dungeon Keys sit beside their doors

The six Dungeon Keys also come as trios, and each trio has a Dungeon Door marker at its edge.

• The northern three are strung along a short stretch of Fainweald’s north edge. Their door sits just east of them, inside the same view as the Crypt Key Door link above.
• The southeastern three cluster a few steps apart on the Mammon side, with their door right beside them and a Healing Charge Chalice right on the door.

What lies past a Dungeon Door is dungeon interior, which the world map does not chart, so the map’s job ends at the threshold.

What does the Unremarkable Key open?

The Unremarkable Key sits on the Mammon side, a few steps north of the Ballistazooka sidearm marker. The game admits up front that its lock is unknown, and the map backs that up: no door, gate, or chest marker anywhere on the world map carries its name. Pick it up while fetching the Ballistazooka and stop worrying about it; whatever it opens is not something the world map can point at.

Vlas’s Cage and the two Locked Gates

Everything else locked crowds into one pocket of northwest Fainweald. Both Locked Gate markers, both Vlas’s Cage markers, and a Breakable Gate sit within a short walk of each other, with a Lever Slot marker beside the eastern Locked Gate. Eredrim’s shell pickup is in the same pocket, so you will walk through here during the shell hunt anyway. Player reports say freeing Vlas is a questline of its own that involves tracking down a key, near the Lonesome Spire rather than at these two cage markers. The Lonesome Spire marker sits at the dead center of the map, far to the southeast of this pocket. No marker on the keys layer is named for him, so the map cannot tell you which of the 18 keys, if any, does that job.
