If you need a lock for your locker, don't use a regular combo lock with the spinning dial. Those things are not fun to open when you are being screamed at and have 5 seconds to get dressed. Get something like this instead. Also get shirt stays (the ones that loop around your feet, not the ones that attach to your socks).
Here's two random tips that will make a huge difference but are super minor. Buy shirt stays and a good lock like this. Do NOT use a regular combo like with a dial. You'll be amazed how hard it is to open when you're getting screamed at.
Good luck!

Interestingly, that Amazon page linked to a Master lock that looks like the one he broke into
