Welcome to Elderfield Keys, Locked Doors, and Passcodes

AT A GLANCE

Identify the lock first, protect consumable keys, and keep verified codes separate from a single unverified player report for the Fish Door.

Identify the lock before spending the key. Welcome to Elderfield references mix physical keys, progression prerequisites, and numeric clues. A code that opens one prompt does not answer every locked door, and a rare key should not be tested randomly.

Match the lock before spending a key

1. 01Dave prompt · 43681A developer-cited record reports 43681; preserve Sam's note because one fan guide prints 43_81.
2. 02Gate lockUse the documented Gate Key route after confirming the destination.
3. 03Skeleton lockUse the documented Skeleton Key route; it is not universal.
4. 04Fish DoorNo sufficiently corroborated current solution is published.

Read the route as text

1. Dave prompt · 43681A developer-cited record reports 43681; preserve Sam's note because one fan guide prints 43_81.
2. Gate lockUse the documented Gate Key route after confirming the destination.
3. Skeleton lockUse the documented Skeleton Key route; it is not universal.
4. Fish DoorNo sufficiently corroborated current solution is published.

Dave's 43681 clue

The stronger developer-cited current reference reports 43681 for Dave's House and connects it to Sam's Cryptic Note. A separate fan guide prints 43_81 with the underscore as literal text. Because those presentations conflict, keep the note and compare the live prompt; this page uses 43681 as the entry backed by the developer-cited record, not as a universal keypad code.

Gate and Skeleton keys

Current references map the fixed Gatekeeper quest keys in order: Burgers Burgers, the General Store, then the Mall F1 lower/back office after the Mall Administrator. They open the west, south-east, and north-east Sewers doors respectively. If a fourth opening stays sealed, do not assume one of those three keys belongs to it.

Basic Skeleton Keys are a different system. A developer-cited reference describes random sources such as garbage, chests, boxes, and fishing treasure; a newer fan record also lists event pickups and later crafting. Treat the source as variable and the key as consumable.

Before using either key type:

1. confirm the name of the blocked location or prompt;
2. compare it with the key's documented destination;
3. keep a clean save or external backup if the key is scarce;
4. use it only when the route and prerequisite match;
5. verify the door state immediately afterward.

If the key disappears without opening the intended route, stop and record the build, location, and prior prerequisite. Do not reload and test every other door from memory.

What to do with the Fish Door

The Fish Door is the one in Old Man Jackson's house that shows a crude picture of a fish. It is still without a developer-published code, and the community key table this page checks does not list it. The Steam discussion about that door ends with the developer saying he would leave the remaining hints to the community, and nobody has posted a confirmed answer there.

One player report, not a confirmed code. On October 9, 2026 a site visitor wrote in to say the combination 639 opened that door for them. We could not corroborate it: no second report, no wiki entry, and no developer statement. It is recorded here because a single specific number is more useful to a stuck player than nothing — but read it as a lead, not a fact.

If you try it:

1. save first, so a wrong code costs nothing;
2. confirm you are at the fish-picture door inside Old Man Jackson's house, not the store door or a Sewer gate;
3. if 639 fails on your build, the report is wrong for you and the door goes back to unknown;
4. if it works, send the build and platform through the feedback form so the entry can be promoted with a second confirmation.

“Unknown” is still a real boundary, not an invitation to try the Gate Key, Skeleton Key, or Dave's code at random.

When a verified answer still fails

• confirm you are at the same named lock as the source;
• complete the prerequisite named by the current route;
• make sure the item is in the active inventory rather than storage;
• test once from a clean save;
• report the exact build and prompt text if the state differs.

If other progress is also missing, check whether the problem is actually a damaged load index using the save recovery guide.

Why these questions stay on one page

Each code or key can be answered in one line, but the player task cannot. The useful answer is the mapping between a lock, its prerequisite, the risk of consuming a scarce item, and whether the route is genuinely verified. Splitting each number into a thin page would add search clutter without helping the player decide what to do.
