You have to put it in the card scanner next to the door to where black widow is :)

its the key code to enter the black widows hq
In black widows hideout, you have to pass the guards first tho...
NO
you get it in early poptropica museum
hi there mr
it is not for any houses.When you are looking for black widow,you have to get past some guards until you reach a door.it has a card hole and you go to your items and press use.
you go to the black house in question, knock on the door and ask if the lady who answers is a widow , if she is ask her for a key. simple
it is for the underground hideout see ya kasey
It doesn't have a key, it's there to distract you; you don't need to open it.
First you travel to Early Poptropica and go into the Art Museum then go to the old lady.... She will give you the key to the Black Widows hideout wich is the old Country House
You'll need it later on to get into Black Widows' Lair.
