Security Air Lock is a small, spherical room in the Pirate Command sector of the Pirate Homeworld. It appears in Metroid Prime 3: Corruption.


The Air Lock's main feature is a large mechanical gate in the centre of the room. This mechanism is blocking access to the other side of the room. The locking system for this device is deactivated by shooting a shifting node which appears on five different parts of the gate. This node must shot in succession to retract all five parts of the lock. However, this node can only be seen and targeted with the X-Ray Visor.

Once the gate has been completely unlocked, a Ball Clamp will glow at the base of the gate structure. This will allow a user to insert a metallic sphere into the clamp. Upon insertion of the sphere, the whole structure will rotate, allowing users access to the other side of the room.
