Yes, you do get keys. We (and by 'we' I mean Duval) get one for our room, two for wardrobes, one to work the gates and sometimes one fo rthe desk drawer. When you pack up your room at the end of each term, you have to put your stuff somewhere, so it's usually in the top half of the wardrobe; if your room is used for a res school, the occupant won't have access to your stuff.
