The master key in BEWILDERED is generally found later in the chapter, not at the very start. Based on walkthroughs, you’ll want to progress through the house areas, then check the drawer/searchable room sections after you get the earlier keys, since the game uses one key to unlock a room that contains the next important key.

Where players usually look

  • The gate key comes first, near the opening area/forest path in walkthroughs.
  • After that, players search drawers and locked rooms for the bedroom/security progression.
  • The “master key” is not clearly shown as an early natural pickup in the sources I found; it appears tied to later progression or a specific puzzle/locked area rather than a random starting spot.

Practical route

  1. Get the first gate-related key and move into the forest/house progression.
  1. Search every drawer, room, and locked side area you can access after that.
  1. If you’re stuck, re-check the rooms that unlock after the bedroom/security key steps, because that is where walkthroughs spend the most time before moving on to relics and the exit sequence.

What this means

If you’re asking about a specific “master key” item, it may be one of the later keys in the revamped chapter rather than a separate hidden item with one fixed spawn. The safest answer from the walkthrough evidence is: advance the key chain, then search the later locked rooms and drawers.

Quick scoop: in Bewildered, the master key is usually found by pushing through the early key puzzles first, then checking later locked rooms and drawers rather than searching the starting area.
TL;DR: **Go past the gate, keep opening rooms in order, and search drawers/locked side rooms after the bedroom/security key steps**.
