Not to be confused with Watchtower Basement Key.

The Basement Key is a key in Dark Souls.

In-Game Description

Opens the narrow passage leading below at the far face of the great bridge in the Undead Burg.
The lower Undead Burg is a treacherous place. Do not turn your back on the wily thieves, or the wild dogs who serve the Capra Demon.


Can be found on a corpse down the stairs from the church in Undead Parish, near the lever that opens the portcullis back to the area with the Fang Boar.

General informationEdit

Opens the door near the bridge where the Hellkite Dragon is. This door leads to the lower section of the Undead Burg and cannot be opened with the Master Key.
