I followed the online tutorials of using the strange key and went to the pile of rocks, and looked into the direction that the environment created a logo, but no interaction is available to me. [url=https://www.youtube.com/watch?v=FDz161Y_tVE]this is the tutorial I found.[/url] I obtained the Strange key from Xur as reputation level reward. Is this some kind of thing that's not available to F2P players like me? Edit: sorted. turns out I was 1 star horse bounty behind from unlocking the progress. somehow I claimed the key first before finishing 3 star horse bounty.
