The Cell Key is a key item in Dark Souls III.

In-Game Description

Key to a cell holding thieves and the like.
The is no shortage of brash thieves in Lothric, and these particular thieves likely scaled the wall from the Undead Settlement.
But they are only willing to practice their thievery on the High Wall, for their fear of Lothric Castle, rumored to devour men, keeps them clear of its grounds.


From the Tower on the Wall bonfire, head downstairs and drop down a level. Proceed through an arch to the outside rooftops with the Pus of Man. Take the ladder down and enter the room with the spear-wielding Lothric Knight. Make way past the knight and find a room with several Large Hollow Soldiers and two Starved Hounds. The key can be found at the bottom of a small staircase, in a corner guarded by one of the hounds.


Unlocks Greirat's cell below the Tower on the Wall bonfire.
