As for the key, I just got off the phone with Ms. Nakajima. She will not be able to open the box prior to next Thursday. As explained to me, opening the box would require an inquiry - and paperwork on their; since the box can only be opened by a programmable device.
However, she has assured me that we will not be dinged because the fire department have not been doing a good job at inspecting the keys in the first place. Right now they are working on bringing awareness to the issue, enforcement will follow.
