<p>I'm afraid it's not possible at the moment. When trying to get the first part of the disk disc again with NPC Sandomo, he simply does not react to any keywords related to the key.</p><p>On the <a rel="nofollow" href="https://www.tibia.com/forum/?action=thread&threadid=4942032">official forum</a>, a player from Belobra said that he contacted Tibia support asking if it would be possible to get a new key, and the answer was NO, but that they are working to fix this issue. So it will probably be possible to get a new key sometime in the future.</p>
