To get the Skeleton Key you just play though the Thieves story line but to keep hold of it you have to then stop doing the questline as the quest after getting it is giving back. Be careful though as some people find after holding off on the next quest it gets stuck and they can't finish the Thieves Guild (the questline is really buggy already).
