Iron Key

The Iron Key is a key found in Tomb Raider 2, in the level Venice

The Iron Key is found in a small room, partially wet, opened by a switch in another area of Venice. The door closes behind you as you enter, and so you must climb upstairs with the key in order to escape, but there is a Brawler and a Doberman is up there, guarding the exit switch.

This key unlocks a door in another part of Venice which raises an Metal Gate, important in completing this level.
