CodeLock code input hook

Greetings, is there a way to hook when player attempts to enter a code to CodeLock.
I'm asking this cause of BruteForce problem with CodeLocks.
I've wrote C# code what should solve the problem, but after i did so, i've found what i can't find a hook where to attack it.
smth like that:

Code:

if (o_lock == null)
                return;
            if (!(o_lock is CodeLock))
                return;
            CodeLock _lock = o_lock as CodeLock;
            if (Locker.ContainsKey(player.userID.ToString()))
            {
                var lockData = Locker[player.userID.ToString()];
                if (lockData.cLock == _lock && (DateTime.Now - lockData.dt).TotalSeconds < 30)
                {
                    if (lockData.usages > 15)
                    {
                        Network.Net.sv.Kick(player.net.connection, "Too much attempts");
                        Log(string.Format("{0} - was kicked for BruteForce", player.displayName));
                    }
                    else if (lockData.usages > 5)
                    {
                        player.ChatMessage("You are trying to brute an CodeLock, stop now!");
                        lockData.usages++;
                    }
                    else
                        lockData.usages++;
                }
                else
                {
                    lockData.cLock = _lock;
                    lockData.dt = DateTime.Now;
                    lockData.usages = 1;
                }
                Locker[player.userID.ToString()] = lockData;
            }
            else
            {
                Locker.Add(player.userID.ToString(), new DoorProtector(_lock, DateTime.Now));
            }          

 

There is no hook available that is triggered on entering a code, and this is actually something that should be handled by Rust and not by a plugin or a patch

 

So, there is script what hack codelock in a seconds. Bump for seatching the way to fix this...
