The Mansion Key is a 'monster drop' that was introduced during the Ratboy's Nightmare Update. It is one of the many collectibles that are needed by the players in order to complete the entries of the Itempedia of the Nightmare. The Mansion Key can be obtained through multiple means that include the following:


In appearance, the Mansion Key appears to be a key made out of hardened bronze and gold. Other than that, nothing much can describe the overall looks of the Mansion Key.

The Mansion Key is mainly used to unlock doors sealed with the keylocks that can only be opened by the Mansion Key. These keylocks are made out of iron, a common material used to make chains and key-locks.

After a player had unlocked and entered a mansion key-locked door, they may explore other parts of The Mansion, The Old Mansion, The Grand Hall, and the Fish Hall that provides different activities the players can do in the zones.


  • If the Mansion Key was discarded or accidentally sold by the player, the players can interact with the Pig to get another Mansion Key.
  • The Mansion Key will not drop upon death.
