This artifact virtually eliminates the need to raise the Security skill, as one can simply auto-attempt until the lock is picked, although skill-ups are still possible with the key.
- Though the Skeleton Key is unbreakable, it is wise to keep a few lockpicks on hand in case the Hero is arrested. The Key is not counted as a lockpick and will be removed if he or she is put in jail.
- See "Discussion" page for the advantages of dropping/picking up the Key for leveling prior to level 60. Also detail on leveling with the Key beyond level 60.
- The Security bonus increases the Security score on the Skills page, but does not turn it a green color (unlike typical fortify effects). While in possession of the artifact, the game treats the player's Security skill as if it was 40 points higher than its actual base value (so, a player with 35 Security who carries the Key will be considered level 75, and an Expert), instead of considering it a standard enchantment. This affects a range of mechanics, notably the experience required to level.
- Although the skeleton key does not behave like a typical Fortify Skill effect, having the key in one's possession does allow access to all "Fortify Skill" options while using an Altar of Spellmaking.
- If the duplication glitch is used with the Skeleton Key, the duplicates do not work; if one has a duplicated Skeleton Key, and no other lockpicks or the original Key, the game will say they have no lockpicks.
- Unbreakable, the Key eliminates the disadvantage that low Security level poses to thrifty players: breaking picks. This makes it a good fit with a Drain Security On Self spell and Auto Attempt.
- The "Security Training" dialogue option will appear and the quest can be completed at Security 30 instead of 70.
This section contains bugs related to Skeleton Key (Oblivion). Before adding a bug to this list, consider the following:
- Blood of the Daedra quest, or entering Henantier's Dreamworld, or by Sanguine's Stark Reality spell, they may be left with a +40 bonus to Security. This is true of other quest items as well. It has been reported that if the Hero is carrying the Skeleton Key when it is removed by a quest, such as giving it to Martin to complete the
- The Hero will no longer be allowed to level their Security while using the Skeleton Key once their natural Security level reaches 60 (100 with the Key). Removing it from inventory will allow Security to level normally.
