i was leveling up in fallout 3 and decided to do some of the campaign/story. i got as far as "farragut west metro station" and i broke the first lock if you know where the key is or you know a way around please say
If you really want to get into that container, you can take the Infiltrator perk which allows you to have a second go at broken locks. I think it's a useless perk, but YMMV.
Spoiler It's better to just practice at the minigame. If you're good at it, you can usually get three attempts to pick a lock before breaking a bobby pin, and then you can back out of the minigame and try again. The lock will reset, but you can repeat this as many times as you need to get the lock open. I've never had to force a lock.
Or you could reload a save previous to when you broke the lock and try it again.
Or, if you're on the PC, you can use console commands to unlock the container.
Other than that, there's really nothing else you can do, and there will not be a key. There won't be any quest critical items in that container, just some random loot.
