Effects[ | ]

Notes[ | ]

  • Both effects work even if the key has been turned into a passive item from items such as Collectible Smelter iconSmelter or Collectible Marbles iconMarbles.
    • Using Pandora's Box with the key in this state will remove the key from Isaac's Inventory.
  • If playing with modal characters such as Character Tainted Lazarus iconTainted Lazarus, the character with the Strange Key must enter the room while holding it to cause the passage to open. Leaving and re-entering the room after switching to the correct character will open the door normally.
  • Unlike with Collectible Mama Mega! iconMama Mega!, Boss It Lives ingameIt Lives must be beaten for the passageway to ?????? to open.
  • If the passageway to ?????? is somehow not yet unlocked, Strange Key will not open the door.

Trivia[ | ]

  • Strange Key is likely a reference to the film by David Lynch, Mulholland Drive (2001), where a small blue box being unlocked by a strange key is a major plot point.
