Once you have the strange key, you need to travel to Eternity. You can then go to Xur’s Treasure Hoard. Once you go through the portal there should be a pile of rocks on the right. The key should work on that pile of rocks. It is here that many people are having the issue.

Check out our guide on how to get to this point. Make sure you have completed all the steps before continuing. After this, the most important tidbit of knowledge that will solve this issue is to understand that this quest is a one-per-account chance.

If you have picked up the key from Xur but it vanishes once you reach the stone formation, this is because you have probably tried it with a different character. If you have a character who has used the Strange Key and others are now stuck on this step, they won’t be able to complete it. Your other character has already done it and it excludes the rest. If the Strange Key says it’s redeemed but is nowhere in your inventory, this will also be the problem.

Some have tried deleting the quest altogether. This has resulted in problems with the Magnum Opus quest itself. If this occurs, it will be best to tag a community manager for advice.
