How To Unlock The Special Doors Inside Final Fantasy XV’s Dungeons – Dungeon Seal Key

Nearly all of the dungeons in Final Fantasy XV feature mysterious locked doors that remain locked throughout the entire story. This guide will tell you how to unlock the special doors hidden inside Final Fantasy XV dungeons so you can open some of the most difficult content the game has to offer.

If you’re an avid explorer there’s a good chance you’ll bump into several of these mysteriously locked doors when completing various dungeons progressing through the game. Sadly however, these remain locked until you’ve completed the entire story – 15 chapters. Once you’ve completed the game you can initiate a special quest that rewards you with the Dungeon Seal Key – the special item needed to unlock the doors inside FF15’s dungeons.

To get the quest for the Dungeon Seal Key head to Meldacia Hunter HQ, it’s the area East of the Vesperpools. Check the screenshot below for the exact location. You need to find Ezma, an old lady sitting on a chair.


Here you will meet an old lady called Ezma. Speak to her to obtain the Dungeon Seal Key, you’re now free to explore 8 brand new dungeons designed exclusively for end-game content. Check out the list of special dungeons below along with their suggest level requirements.

  • Keycatrich Trench Dungeon – Level 55
  • Fociaugh Hollow Dungeon – Level 65
  • Greyshire Glacial Grotto Dungeon – Level 65
  • Daurell Caverns Dungeon – Level 72
  • Balouve Mines Dungeon – Level 78
  • Steyliff Grove Dungeon – Level 86
  • Crestholm Channels Dungeon – Level 92
  • Costlemark Tower Dungeon – Level 99

Ezma Won’t Give Me The Dungeon Seal Key

As well as completing the game you must have completed other dungeons before Ezma’s quest becomes available. These include Crestholm Channels, Balouve Mines, Costlemark Tower, and Daurell Caverns.

    So I’ve completed all of those dungeons and finished the game, but I still can’t get the key from her. Any idea why?

    • Waterflu

      Just to double check you’ve beaten the game, being now on chapter 15 and completed the quests for all of them 4 dungeons? You can check on Quest (Completed) Costlemark Lvl 55, Balouve Mines Lvl 50 Crestholm Channels Lvl 45 Daurrel Mines Lvl 25-27 I believe.

        So the mines has 2 missions

      I dunno if you’re still stuck but you need to do everything in Costlemark. It made me stuck for ages because I didn’t realise you had to kill Jabberwock.

      for me, I assumed it was just “all the dungeons with weapons in” to get her to cough up, in which case sad old Daurell Caverns was easy to overlook, so that’d be my guess

      Pitioss Ruins – secret dungeon?

      • Zev

        Evil dungeon

  • Mr. Sinclair

    If I finish the game without doing those dungeons, will the quest unlock once I beat them in new game plus? Or am I better off playing the game all over again and power leveling to the point that I can complete them?(which would suck as I put 60+ hrs into my first playthrough.)

    • PixelOmen

      I don’t see any reason why you couldn’t do them in new game plus.


    im writing this because i had issues with getting the key despite having all doors found and dungeons completed and the game. i had not saved a new chap 15 file. and it didnt work. when i saved it on the second try, Ezma was able to give me the key. because my save file said chapter 15.

    I’m so mad .. I have 170 hours I am on my 3rd run did all the dungeon and this old hag still will not give me the key..please help me .. before I grow the freaking remote out the window again.. please.

      AFAIK you need to have completed all the dungeons and found the hidden doors in each. You may have to revisit each to make sure you find the door, one is tricky to get at so read up on the specifics before you go searching.
