The Thief's Key is a recurring item that is needed to unlock certain doors and/or chests. It's usually the first key in the game to be found.



The Thief's Key is an item in Dragon Quest III. It is the first key acquired in the game. The key is held by an old man at the top of the Tower of Najima. The key is able to open yellow doors.


The Thief's Key is given to Alena in Chapter 2 after she saves Anya from the kidnappers, and is needed to get through Birdsong Tower. In Chapter 5, she still has the key upon joining up with the hero. The Thief's Key unlocks blue doors.


The Thief's Key can first be purchased at the The Bazaar in Haggleton. The price for it starts at 2,000 Gold Coins, but it can be bartered down to 200. The shop selling it closes after the Ra's Mirror is obtained.

It is also available for 200 Gold Coins at the item shop in the inn at Somnia in the Lower World. The shop closes after Murdaw is defeated.


The thief's key can be created through alchemy by combining a bronze knife (available at the Peregrin Quay weapon shop) and an Iron nail.


The Thief's key is an important item in Dragon Quest IX.
