Question about the location of a key item.

[The Dude]

Near the entrance to the route to Sunnyshore City, there's this girl standing in front of a house. She says she's lost her house key.
Does anyone know where the house key is?

I asked this about a week ago, though I don't expect you to find the page. It's just outside the reception doors when you enter the resort, use your Dowser App. and you should flush it out. You only get a Lava Cookie though.
