break it open
You can't you have to find all the comic pieces then you can open the locker.
The combination is 9305.
The comic pieces assembled will give you the code combination. Click on the stuffed locker, and it will show the lock. (*code is 9305, but knowing that will not get the locker open until you have collected and assembled the comic)
find out the combination and don't do anything stupid
When you assemble the comic strip (8 pieces floating around and a frame), the locker combination is written in the margin. You have to get the comics because otherwise the locker will not open. (see related question)

It is required that you get walloped by the locker (as shown on the comic strip). You can still get up and get the blueprint. You need to collect the comic strip pieces and assemble it before you can open the locker, but the code is 9305 (vertically).
You have to put together the comic strip. There is a secret message across the middle (Nate wrote his locker combination on it). Once you have the comics, go to the locker and dial the combination. After the mess settles, click on the pile to retrieve the blueprint.
The answer to the locker problem is every perfect square is a locker that is open.
If the drawers don't open (in the detention room), you obviously haven't got the blueprint from Nate's locker. Go out of the detention room and click on the messed-up, overstuffed locker. The combination is 9305. The locker will open and blast open to the side. Go back to the locker and click it to get the blueprint map. Then go into the Detention room (use the stink bomb if you haven't already) and open the filing cabinet. (see related question)
To open the lock you enter the combonation that comes with the lock and pull up on the shackel. to close it, put the shackel in the hole on the lock and push down.
His locker is on the second floor of the school, and it is stuffed with junk. Once you get the comic pieces, you will see his locker combination (9305). Open it and then recover the School Blueprint from the pile. (see related question)
