You need to have the following keys:
The keys and keycard must not be lent to anyone else, and – should you lose them – you have to replace them by paying 200 kr. for a new keycard and 50 kr. for a key.
Remember to lock your room when leaving it. The doors of the boarding school are locked at 6 p.m. and you have to use your keycard. If you get home later than 11 p.m. check that the outside door locks after you.
