When Mr.House wants you to destroy the Brotherhood of steel but you need to find the 3 self destruct keys. I've talked to everyone and can't find them.

Obviously the BoS isn't going to give you the self destruct keys if you ask them for it, duh.

You have to either pickpocket them off the owners or kill them and take it.

lol yeah here u got have the key that will blow up are base lol but i just killed them all and got them lol i thought thats all i had to do was kill them lol but come to find out i could just blow them up lol
