Dungeon Lock Outs are several dungeons in The Elder Scrolls V: Skyrim that are not open to the Dragonborn to begin with. Some are heavily based in quests, and so to prevent the Dragonborn from breaking the quest, they need to have them active for the dungeon to be available.

- On PC, it is possible to hit the tilde (~) key and type "tcl" to toggle noclip and move through these barriers or, in the case of doors that must be unlocked by quest characters with keys, click on the door and type "unlock" to unlock the door. From here you can explore the dungeon as normal.
- This defeats the purpose of the wall and will break the quests that pertains to it.
- Several of the locations can be entered from the hidden "exit." Using a collision glitch on consoles will open most areas.
- Some player-made modifications (such as Live Another Life) can spawn the Dragonborn in places that are blocked off (such as Blackreach), nullifying the purpose of the lock outs.
- The interiors of a large majority of these dungeons will never respawn, meaning that the Dragonborn can safely store things inside containers, and they will still be there if the Dragonborn returns. This is not necessarily the case with the exteriors, which tend to respawn within 10-30 in-game days, meaning that containers outside may respawn as well.
