My DH buy me one just like it. with no key!!! If you take a samll sreew drive and put it in the hole and ture easy you sure be able to get it open[ a drop of oil in the hole may help]. If that dose not work if you can get the top away from the base just a little you can slide a knife in the space and move the lock that way. If you was close I would love to help find the baby in the box.
