You could have only gotten a Mystery Gift through Nintendo in order to access the Harbor Inn in Canalave City in Pokémon Diamond however the key that's needed in order to gain access to the Harbor Inn, the Member's Card, it was never released for Pokémon Diamond so the only way for you to get the Member's Card is to use a cheating device such as an Action Replay or Pokésav.
This key is non-existent.
