[Q] .kl file issues - Xperia Z2 Q&A, Help & Troubleshooting

I've been running my xperia Z2 for a month or two now and one of the first things I did was disable the camera button, and attempt to rebind it to a different button in the .kl files within system/usr/keylayout. Initially, it worked great. I commented out the key 212 camera in a few files with a #, and added a new line.
It's been a month or so since then and I hadn't been using the camera button and all, and recently I've noticed that the kl file changed back in one of my restores to just being commented out, so the camera button is now non functional. I attempted to add a line of code to change the camera to media next like this: key 212 MEDIA_NEXT, but was getting no response after restarting my phone. I removed the line, deleted the comment on the previous line in every file that I had disabled it in, and restarted the phone. Camera is still non functional even after confirming it stayed unchecked.
After this, I attempted to copy all of the files to my SD card and mass edited every single camera key reference to media_next for the sake of testing, and the button was still disabled. I completely purged my .kl files, and uploaded notepad++ edited copies and restarted my phone. None of my buttons worked. I did a restore from my SD card backup, and nothing worked after restarting, still. I did a backup from a TWRP backup and everything is functional again... however, I'm left wondering why my .kl files might not be reading.
I apologize for the long post, but I'm trying to understand where I've went wrong. I'm on a stock bell rom(canadian) firmware 4.4.2 model D6503 build 17.1.A.2.55. I'm rooted, with only minimal modifications to the device(cydia substrate, xposed framework using rootcloak, youtube adaway, a radio modification to allow headphoneless scanning and xposed additions).
Does anyone know where I might've went wrong? My end goal is to rebind a controller's R2(simple button) controller to the R2 axis as well as button press, so if anyone has any information on rebinding a key to a maxed out axis I would appreciate information on that as well(Eg. R2 key 105 to RTrigger 1.0 + key 105).

Not sure
Perhaps copy a working existing file and try from there
I had trouble understanding your problem

I've restored a CRM backup and the .kl files all work great, but when I attempt to modify the files they don't seem to update any system functions or buttons unless I'm just disabling the button. Even if I copy the file to another directory, break all the buttons then overwrite it with the copy and restart, the buttons stay disabled until I restore a CRM recovery.
I hope that's a little easier to read, the phone just doesn't seem to update its internal system with button definitions except to disable them, and I'm trying to figure out why.

Just a thought, not pretty sure.
When you are copying files from sd-card, you should also check for correct permissions.
Your permissions must match with original files, otherwise it may create an issue.

I hadn't even thought of that, thank you, I'll try that out
