How do I get past the guards

Hint 1 of 7:

Don't be confused by the box versus trunk wording.

Hint 2 of 7:

Put your Jet-Pack into the trunk, you won't be needing it again.

Hint 3 of 7:

Push the trunk over to the vent.

Hint 4 of 7:

Climb up, and loosen the vent with your knife. (From the pod, remember?)

Hint 5 of 7:

Go in and explore until you find a dead end with a screen.

Hint 6 of 7:

Kick in the screen. (NOOO, not the computer monitor screen!)
