To get the Skeleton Key in Oblivion, you need to complete the Daedric quest “Nocturnal,” which becomes available once you hit at least level 10.

Quick Scoop

  • The Skeleton Key is an unbreakable lockpick that also massively boosts your Security while it’s in your inventory.
  • You unlock it by doing Nocturnal’s Daedric quest at her shrine northeast of Leyawiin, but only after reaching level 10.
  • The quest is short: talk to the shrine, track down the Eye of Nocturnal in a nearby cave, return it, and you’re rewarded with the Skeleton Key.

Requirements

  • Be level 10 or higher ; the Nocturnal quest will not start below this level.
  • Be able to travel safely near Leyawiin (ideally with some potions, armor, and basic combat readiness).

Step‑by‑Step: How to Get the Skeleton Key

1. Find the Shrine of Nocturnal

  1. Travel to Leyawiin on your map.
  2. From Leyawiin, head northeast into the wilderness to locate the Shrine of Nocturnal.
  1. You’ll find a Daedric statue in a small clearing; that’s the shrine.

Think of it like a secret club door in the woods: once you know the spot, it’s easy forever.

2. Start the “Nocturnal” Quest

  1. Make sure you are level 10, then approach the shrine and speak to Nocturnal (or the worshippers, depending on your version).
  1. Nocturnal asks you to retrieve the Eye of Nocturnal , a stolen artifact now in the hands of thieves tied to Leyawiin.

This conversation officially starts the “Nocturnal” quest.

3. Track the Eye of Nocturnal

  • The quest will point you toward leads in Leyawiin , eventually sending you to a nearby cave (often referred to as Tidewater Cave in remaster guides).
  • Follow your quest marker toward the cave entrance outside the city.

Inside the cave:

  • Expect creatures like bears or trolls in the remastered version.
  • The usual route advice from modern guides is:
    • Keep taking left turns as you progress deeper.
    • You’ll reach a flooded tunnel ; dive underwater and follow the passage.
    • Look for a small underwater opening on your right that hides the Eye of Nocturnal.

4. Return the Eye and Claim the Key

  1. Once you’ve looted the Eye of Nocturnal , leave the cave (you can backtrack out and then fast travel).
  2. Fast travel back to the Shrine of Nocturnal.
  3. Activate the shrine again to speak with Nocturnal and hand over the Eye.

When the quest completes, you receive the Skeleton Key as your reward.

What the Skeleton Key Actually Does

  • Functions as an unbreakable lockpick , letting you attempt locks without worrying about losing picks.
  • In remastered guides, it’s noted to give a huge Security skill bonus just by sitting in your inventory, making even hard locks much easier to crack.
  • Because it’s unbreakable, you can often spam Auto Attempt on locks instead of manually playing the minigame.

A lot of players grab it early because it turns exploration and dungeon- delving into a much smoother experience.

If You Lose the Skeleton Key

Players sometimes report losing or dropping the key by accident and discovering it missing in later saves.

  • On PC , some people resort to using a console command (with the right item ID) to re-add it, though that can disable achievements.
  • On console , the usual answer is: you must either find the spot you dropped it or roll back to an older save.

It’s wise to treat the key like a permanent artifact and avoid dropping or storing it casually.

Mini FAQ

Q: Do I need to join the Thieves Guild first?

  • No, you only need to be level 10 and find the Shrine of Nocturnal northeast of Leyawiin; the Thieves Guild is not required.

Q: Is the Skeleton Key missable?

  • No, as long as you can still access the shrine and start the Daedric quest, you can get it at any point after level 10.

Q: Does it completely replace lockpicks?

  • For normal gameplay, yes, though some guides recommend keeping a few regular lockpicks as backup in case guards confiscate your gear when you’re arrested.

TL;DR:
Hit level 10, go northeast of Leyawiin to the Shrine of Nocturnal , start the “Nocturnal” Daedric quest, follow the marker to the cave, keep left and swim through the underwater tunnel to grab the Eye of Nocturnal , return it to the shrine, and you’re rewarded with the Skeleton Key , an unbreakable, Security‑boosting lockpick.
