Keys are for Cowards

Keys are for Cowards is an achievement in Fallout 3 which is awarded for successfully picking 50 locks. One interesting note, the achievement image shows an open lock with the number 100 on it, even though the achievement only requires one to pick 50 locks (but maybe it depicts a Lockpick skill of 100).

Exploit Quote(Another entry is south west of Rivet City across a bridge. The door is locked "Very Hard" (requiring a Lockpick skill 100) on both sides. Alternatively there is a power switch to the right of the door, when used this unlocks the door as well, but this can only be accessed from the inside of the bow. If you enter this way, watch out for the Frag Mine that is placed on top of an empty Ammo Crate. If re-locked via the trigger, the door will drop to "Easy" for unknown reasons. ) you can re-lock this door and pick unlimited time for a easy achievement - Panchs7331
