Finally, I had time to finish and upload the recode. Thanks wardog for the help!
List of new:
- Removed CF as a dependency.
- New config, new way of raiding, raid times, ability to disable attachment to tents/gates, ability to enable/disable raiding tents/gates
- Raiding changes. Raiding can now be broken up into multiple increments instead of having to hold left click for an entire hour. Raiding now decreases the health of a codelock based on time/raid increments and is removed at 0HP. Lock HP is visible from the raid action!
- Owner / Guest persistence! After entering the code once, you never have to again!
- Owners: Owners have the ability to remove the passcode or change it. They are also now the only ones capable of dismantling a gate.
- Custom Logger! Finally, Code Lock now tells you what's going on with locks! You no longer have to wonder what was going on. Client synchronization, raiding, attachment, passcode changes, admin usage is now all logged!
- Admin Permissions! Again, finally! Admins are now capable of removing, changing, or simply opening a codelock without knowing the passcode or having to cut the lock off entirely. Permissions for each setting can be set based on a users steam64id.
- Rate limiting! Actions and UI calls to the server now have a configurable rate limit! This will prevent users from spamming RPC requests to the server.
- More that I probably missed

Bug Fixes:
- Most notable, the UI issue. The UI will no longer randomly disappear to never appear again until you restart your game.
- Probably introduced more bugs given this is a complete recode. If there are any issues, leave them in the comments.

Notes: The new config is located inside of the server profile folder in CodeLock, same with permissions and logs.

- Fixed exploit: Splitting stacks
- Fixed exploit: Combining stacks
- Moved functions that open UI client-side since it makes far more sense then using a server-call. This will remove latency when opening menus.

- Removed ability to use ruined tools.

- Fixed null ref
- Config now pulled from server when a user joins, so tents will properly show the attachment slot for codelocks based on config.

- CodeLock moved to its own class. All old CodeLocks are now broken. If the code "reset" doesn't work, cut them off and reattach them.
- Visual bugs fixed. Lock will now show proper animation states.
- CodeLock won't show attached animation state until a passcode has been set. I know how to fix this, but I don't have time to test it right now.

- Fixed so core works with DayZ 1.04
- NEW KEY, copy the new key to your server keys folder or users using this mod won't be able to join
- BUGGED BTW. Was not home all day and they changed how combinationlocks work ( again ) so now I have to fix a few things relating to animation states and the option when trying to open a gate.
- When looking at a codelock on a gate, it will ALWAYS show "Enter Passcode" whether it's locked on the gate or not. This is a bug, it'll still open the correct menu.
- When the lock is removed from a gate, it will remain in the animation state as if it is still on the gate.

( If there are any other bugs, let me know by commenting on the steam page or in my discord )

- Fixed not being able to add/remove loot from OP_Items Improvised Tent ( Thanks Cleetus )

This update took way too long.
Lots of changes for this one.
Added:
Tents!
- CodeLocks can now be attached to tents (This is configurable through the server)
- Cannot remove/add gear from tent if door is closed and tent is locked
- Cannot pack tent if tent is locked
- Ability to attach the lock by either looking at the center of the tent from the inside, or looking at the door when the CodeLock in hand
- Ability to saw off the lock on tents using a hacksaw (Configurable, uses the same variable as fences)
- CodeLock category hidden from tents if not enabled on server.

- Action to enter/set the pin now comes up at any angle as long as you're looking at the right part of the fence
- CodeLock action completely recoded to work on tents and fences
- Enter key now works when entering/setting the pin
- Rework of the UI, now more conservative
- Some more that I might've forgotten?

Server Owners:
If you wish to enable code locks on tents for your server add <"m_CanAttachtoTent": 1> ( remove the carrots ) to your CodeLockConfig.json

- Custom Model!!! FInally! All thanks to OP!

Model Used: https://sketchfab.com/3d-models/keypad-b9968a00bc9249df927ff1969acf2f7e
OP Steam: https://steamcommunity.com/profiles/76561198379941795/

- Fixed issue where attachment state wasn't updated properly, so the attachment slot wouldn't lock after removing the lock, then attempting to put it back on.
