Fallout 76: Find Rosalynn's Master Key Holotape - Key to the Past

Find Rosalynn's Master Key Holotape is an objective in Fallout 76 (F76).

Quest[edit]

Now you will need to head over to the West into the next room.
Explore around the room just a little.
You can head over to the left to the locked cell (level 0 lock) that has the corpse of Roaslyn.
While you are working on this, you will be contacted by Rose.
She will tell you that she is trying to break into the cache, and claims that her "Ms. Nanny" programming is stopping her from making off with everything.
She will tell you to just head on back.
