Throughout your travels through the vast world of Dragon Quest XI, you will encounter various locked doors you won't be able to access until much later on. There are two types of keys to be acquired, one that is mandatory for the story to continue, while the other is optional. Hopefully this guide will help you locate any doors you may have forgotten about along your journey.


Magic Key

This is a story related key that you won't be able to miss, and it will unlock various red doors across the world you may have spotted, exclusively in cities and in the field. The second key is where you will be able to unlock those mysterious ones in dungeons.

Ultimate Key

The Ultimate Key is located in Havens Above - Place of Legends, which is where the giant memorial is that describes the unfortunate history of the world. It's located in a treasure chest right in the middle of the area and probably best to grab it when you first visit here to talk to the elder. This key unlocks the remaining doors across the world which is indicated by a silver lock on the map.
