Welcome to Elderfield Keys: Every Locked Door Explained
Every key and what it opens
| Key | What it opens | Where to get it | Consumed? |
|---|---|---|---|
| Mall F1 Hallway Key | Opens a door in the mall food court to the back hallways. | Given by Adrian at the start of the Tentacle Cleanup Task | No |
| Small Mine Key | Opens small mine doors. / Consumed on use. | Foraging (Mall Mines) / Purchased from Mall Rat / Purchased from Forge Shop | Yes |
| Basic Skeleton Key | Opens a variety of basic locks. / Consumed on use. | Answering "knowledge" on one of Edwin's events / Found in Old Man Jackson's closet / Found in chests in Mall Mines | Yes |
| Fancy key | A fancy looking key. / It likely opens a similarly fancy closet door. | — | No |
Mill Key
The Mill Key is needed for the task The Local Jogger's Club. It is found in the ever-shifting Old Woods, on the map screen with the giant statue — the Old Woods layout reshuffles, so the statue screen is the landmark to look for rather than a fixed direction.
Gates and second keys
Players regularly get stuck on a second gate key in the Gatekeeper sequence and on doors in the mall back hallways. Those doors are opened by task progression rather than by a findable key: check the tier the door sits in on the task list and finish the chain that names it.
Door codes
There is no verified public list of numeric door codes for the launch build yet. The demo's puzzle notes are randomised in places, and no source we can check publishes the full set, so this page does not print numbers that might be wrong. It will be filled in from the launch build after September 10 rather than guessed at now.
