Fallout 3 help

Im doing the Blood Ties quest trying to raise some caps to buy the info from Moriarty...

Ive found the Family in the Metro and have to locate Ian West...i presume hes in the room with the only locked door in the place...does anyone know where the key is...or how to get it??...

Thanks in advance...

You might want to put that in the Fallout 3 forum.

For topics speciffically for one game you will probably get more helpful advice and you will help other people that look in that games forum that are having the same problem.
