book with hanging keys on the cover? [s]

[lindsey]

Boy lives with his mother, I believe his father died(?) and left him a box of his things that is locked. Lives in the apartment next to his best friend who is a girl and they have a hole in the wall to pass notes through. Goes on a quest to find the key to unlock his fathers box. Goes to many garage/ rumage sales to find keys.

Yup. Good book. Jeremy Fink and the Meaning of Life. Wendy Mass is one of my favorite MG authors.

There's a movie that came out recently, if you like the book. I haven't seen it, kind of afraid of spoiling the book . . .

Too bad lindsey never confirmed this, but it is such a perfect fit that I'm considering this Solved.
