There are three ways to do this and one is potentially glitched (at least it glitched out on me)
When you talk to the delivery company boss at Groundbreaker, she'll task you to get a navkey from a local merchant.
Now, if you're speech skills are pretty much rubbish, you'll not be able to buy the navkey which costs 1,000bits. She'll offer you a job.
The job is worth doing as it unlocks Rosewood. Which is a huge boost to Xp. Make sure you find all three secrets if you go this route, as returning two and lying that there's nothing else to find, causes her to glitch out and she talks in circles on the same subject.
I had to kill her and her pals and then travel to Monarch's Stella Bay by foot. running passed all the mega creatures on the way.
So your options are buy the key but miss out on XP, do her side quest and then buy the key or kill her if she glitches and run there. In truth, you don't have to kill her, but she and her guards do drop some nice gear.
