Is there a way of getting the Skeleton Key without doing the Thieves Guild?

I'm collecting the artifacts as a mage but I don't feel like doing that questline.

The only way I know of is to download the mod for the key,its in the work shop.

No, don't think so..

Without mods or console commands on PC, the answer is no.

Or just get lockpicking to like 90 or something and get the unbreakable perk.
