After you build the key the Derelict ship appears on the star chart. (At the top & slightly to the right). You can only select nodes you have keys for.

Do I need story progression to access it? Because I don't bloody see it and someone in My alliance mention that.

Don't tell me to build keys. Don't tell me to go to the marked. Just tell me what to do after I equip the key and where to go.
