This is CM13 we are talking about. I'm just not sure anymore
Well, first you should inform yourself about the possibilities CM will give you. The installation actually is pretty easy (if you're doing it correct). But keep in mind: There's a possibility of bricking your phone thus turning it into a pretty expensive paperweight. If you do not absolutely need it you should either let someone do it for you or let it be because even if you've installed CM successfully there is a chance of bricking your device afterwards (aka when it's rooted) as every app that you give access to the root can change system files. So you always have to be careful on what permissions you give to apps.
If you just want another user interface then you'd be better of installing a theme you downloaded from the playstore (I use CM 12.1 on my S3 mini and installed TouchWiz afterwards cuz I got used to it).
So ye, inform yourself about the possibilities and then decide if you really need it. When you've decided I can help you installing it.
If you care about a warranty if you have one, then I wouldn't do this at all. Installing CM will certainly trip the KNOX e-fuse, permanently leaving it in the voided state (0x1).

I use Verizon. No clue if it works. Am skidling
You cannot unlock your bootloader without having the developer version of the phone. Installing CM is impossible to do so without unlocking the bootloader, as the original bootloader state does a check on if the integrity of the system is signed by Samsung/Verizon. There are ways to bypass the Verizon signature, but there are no ways known to bypass the system check for Samsung every bootup. The check happens before it even begins to boot Android, making it nearly impossible to create a workaround. Like the KNOX e-fuse, it is a hardware based check with no known way to avert the process.
tl;dr: You can try it, but you'll end up bricking your phone.

I'd doubt he'd have a warranty on his phone.
About the e-fuse, can't he use Triangle Away from Chainfire?
yeah

That's not how this works. Triangle Away has nothing to do with what happens while the bootloader is initializing nor before it. What Triangle Away does is remove the Samsung OEM alert that is given when it finds that the software has been tampered with, but is deemed safe to proceed in the boot sequence. The KNOX trip is detected before Android even boots, as it can be seen in the phone's "Download Mode". This is an extremely low-level hardware check that's pretty much impossible to get around, and a void code (0x1) pretty much fucks you over in terms of warranty. It's also been speculated that this trip also disables certain functions of the phone's low-level systems, but I can't recall them off the top of my head. The two are very different things and should not be confused. One is temporary and can be fixed with stock firmware, while the other is permanent and irreversible. An e-fuse is something physical. Once something trips it, the fuse burns and is no longer present. This is usually done on secure systems to prevent the use of tampered systems or use of unauthorized software. There is no way to replace the fuse without replacing the entire phone, as it is manufactured WITHIN the main board.

BTW that Write Protection mode is the thing that prevents people from installing ROMs not based on TouchWiz/Samsung firmware.
