You must have been using a quite old Firefox version if that version still used a distinct Sync key. Firefox 29 and later no longer use a specific Sync key, but derive the Sync key from the password of the Firefox Account that you use to log in to this account.

You would need a Firefox 28 version to connect to an old Sync account that used the Sync key.
