does anyone know how to

Make nice with the faction that owns the safehouse. They then give you the key.

thank you

Still have not got that followers safehouse key :toughninja:.

I had to do a LOT to get that safehouse. Don't know if it would be considered spoilers so I'll just err on the side of caution:

Or you could give the followers a bunch of chems and get fame that way

Alternatively,

(click on door)
unlock
`
Open door.

But that's not the way winners do it.
It's far more satisfying to get access the hard way.

What pisses me off about the BoS Safehouse is that it is only helpful for heavy weapon classes, at least the FotA safehouse has gear for different characters, even NCR and Caesars legion to an extent, BoS? Nope. All big guns, not one Tri-Beam Laser Rifle or Gauss Rifle

Ranger Safehouse - get "Liked" by the NCR, report to Col. Hsu
Brotherhood Safehouse - finish all marked Brotherhood quests, report to McNamara/Hardin
Followers Safehouse - do all Freeside quests, give as much RadAway/Med-X/Fixer as possible, report to Julie
Legion Safehouse - be a rapist, sixist, hypocritical [censored] and kill yourself

Actually for the legion if you don't want to be a jerk in game, just pick pocket about 35+ dog tags (at least ten troopers with tags can be found at Camp Golf, Camp Gaurdian, and Camp Forlorn Hope only a few at MacCarran though) and hand them to Aurilious of Phoenix at Cottonwood Cove till you are liked, then ask Lucius at the Fort (sometime he has you start his quest first of getting a part for the legion howitzer).

The entire concept of "locks" is amusing in a game where any player is going to run across more explosives than they'll probably ever use. Dynamite, C4, even IEDs made of missiles, grenades and landmines. You could blow the door to splinters or just dismantle the entire building.
