once you've chased the thief and get the key card, go to the museum. You'll get a package. go into the inventory and use it. drag the thingy bobber over the painting. it says go to the pop art museum in early poptropica island a old lady should be there. talk to her click the "what can i do" option. she will give you the key! hope this helps anyone!
Since you couldn't find a key to unlock the cottage in the Country Side, this is probably it.
If you are referring to the keycard in Poptropica Counterfeit Island, you use it to unlock a door in the secret lair, which can be found in the countryside. It is locked so you have to find a key.
Around the island, there are pieces of paper. Find all of them and piece them together to find out how to unlock the lock. Good Luck!
After you unlock the house you go in and then go to the second floor, as soon as you get there theres a painting. on the top right corner of the painting there a piece of paper stickin out. click on it and then you done.
First go to skullduggery island,take your ship to a island called Keys World island and you will find the key of the chest on counterfeit island!;)
You don't unlock it. There's nothing in it, and you can't unlock it, anyway. If somebody does unlock it, please edit this answer. I'm curious to learn if you can unlock it.
You have to get that painting and then scan it.It would tell you to go to the Early Poptropica Muesum.Then go there, and there will be a lady wth a long skirt.Talk to her then you'll get the key and that's the key to unlock the house!!!:) Hope that helps! :)
You have to complete the island to unlock that surprise.
If you have received that package from the curator, and gotten the key at Early Poptropica, then you can unlock the house in the Country Side. Tear back the painting on the second floor. You'll find her, or rather she will find you.
When you finally receive the key to the Inspector's house (from the Museum curator, who is in Early Poptropica), you may have some idea who the Black Widow is, especially with the name "Veuve Noir" on the sign.
You do not have to find the key. It is given to you later in the game.
You use the key from the Curator to unlock the Inspector's house in the CountrySide.
