Atsuraelu

Hello everyone! I've got a little problem with the daycare quest and hoped someone could tell me what I'm doing wrong... I beat the imposters and I've gotten the warehouse key, but every time I try to use it on the warehouse it says: "It's locked! | Atsuraelu used the Warehouse Key. | ...It didn't work!" Thanks in advance. edit: *facepalm* Okay I was being extremely stupid... Thanks NovaKnight!
