When you go to ISBNDB.com and log in using the Account link at the top. Then got to "Developer Area / API" link. From there link on Manage Access keys. If you have no keys listed you need to click "generate a new key". Other wise you just copy the key that is listed. This is the key you have to provide to calibre in the "Access Key" field on the fetch metadata from server dialog.
