I have speculated that the seventh is in the hands of the wesen council and is in the spice shop.

The key Renard gave to Nick was Nicks own key; you know, the one Renard had stolen from Nick earlier in that same episode. He was returning what was rightfully nicks rather than adding to nicks collection.
