Skeleton key without the fortify effect

This only modifies the Skeleton key Fortify Security effect to 0 for all your leveling needs, since it's a fortify effect added by an item, your level in Security will progress more slowly as if you actually have a Security level +40 compared to temporary spells. ( At least from my testing, and even then, lower Security level means more failures on auto lockpick which results in more XP anyway. )

Install like every other ESP mod, shouldn't conflict with any mod unless it alters the skeleton key magical effect, if you already have the Skeleton key, you will need to drop it and grab it again for the effect to update.
