FYI ...

I'm seeing the Unlock Icon center screen when I'm mounted in th epilot seat of an ATTACK HELICOPTER.

In other vehicles, when I ALT look around it comes and goes; but is NOT on when I'm NOT ALT looking and my eyes are looking dead center.

Didn't see anything in the settings file for this; perhaps it's just a new Rust Feature (bug).

This is due to how the Rust client works. It's not fixable.

I've noticed that when mounted in the pilot seat when you ALT look 90° to the left/right/up/down the Unlock icon disapears.  In other words, if the Code Lock is within the player camera's view frustrum then you see thet Unlock icon.  So if you also allow for rotation of the Code Lock (i.e., X, Y, Z) it should fix this issue.

There are certainly alternate positions and/or rotations for each vehicle that resolves this issue.  For example, I have a mod that adds a coffin to the bottom of the Attack Heli and when a code lock is palced on it I DON'T see the Unlock icon as it is outside of the player camera's view frustrum.  Same for the mini, put a crate on the back with a Code Lock on the back and you DON'T see the Unlock icon when mounted.

But then again, it might have something to do with the camera itself.  That is, perhaps it's not the player's camera that is active when you are in a vehicle, or perhaps the player's camera is moved/altered once you mount a vehicle.  Or some collider is added to the vehicle and no matter where the COdde Lock visibly is, you will always be inside of the collider that triggers the display of the Unlock icon. :(

I have experimented with alternative positions, but it's either not immersive or not feasible for most vehicles. You can experiment with alternative positions by editing the plugin if you would like to propose some different positions.

I think my last paragraph actually nailed the issue.  In most cases, the player is never inside of objects with Code Locks on them so the view frustrum check works as intended.  But when the player is inside of the object with a Code Lock the frustrum check fails.  And if that is the case, then there isn't anything anyone but Facepunch can do about it.

Sorry for bring this up again, but I now 'Grok' the issue. ;)

ThanX for the fast responses and for your mod!

I've had a report of this being annoying as well on my server.

I found a setting players can change so that only the center dot appears, no text and no icon: Search for "Interaction Crosshair Mode" in settings and set it to "Minimal". Though this applies to every interaction, not just this (doors, containers, etc.)
