Obviously not the issue here... Room number came from the reservation system (which should have flagged the room as occupied) and the agent was just following directions in making a key for the same room.
Now if the key was made using the next sequence number, the current occupant would be locked out next time trying to enter the room. That's why they ask if you need another key if you lost your previous key(s) so they can invalidate the old ones or just issue a copy of what you had.
