Forum:Uncle roe's storage key

If you kill Uncle Roe, you find his Storage Key at the corps.

I just can't find the lock to open with this key. It's not in his house (there are the storages of the caravans). If you are in his house at the bottom of the stairs, you can see trough the broken doors, that the roof of the garages had collapsed. Maybe this was the storage and it has been destroyed. I couldn't find anything else in Canterburry Commons where i could use this key.
