function onClicked(Plr)
    local Char = Plr.Character
    if Char:FindFirstChild("Blue Master Key", true) then
        Char:FindFirstChild("Blue Master Key", true):Destroy() -- Removes tool from players hands
    end
    if Plr.Backpack:FindFirstChild("Blue Master Key", true) then 
        Plr.Backpack:FindFirstChild("Blue Master Key", true):Destroy() -- Removes tool from players backback

Hello, kexiGamer!

This script completly removes the key from the player! Removes from player hand and player inventory =D

Hope you like it!

script.Parent.Touched:connect(function(hit)
    local Humanoid = hit.Parent:FindFirstChild("Humanoid")
    if Humanoid then
        for i,item in pairs(hit.Parent:GetChildren()) do
            if item.Name == "Blue Master Key" and item:IsA("Tool") then
                item:Destroy()
            end
        end
        for i,item in pairs(game.Players[hit.Parent.Name].Backpack:GetChildren()) do
            if item.Name == "Blue Master Key" and item:IsA("Tool") then
                item:Destroy()
            end
        end
    end
end)

Good luck with your games!

Hi there and thanx for your answer I get: "Request was throttled. Try sending fewer requests. Key = 551800471 (x4) " and (x4) is just growing and growing. No item dissapears from inventory.

Here is my the script that is working but it is not removing only "BlueMasterKey" tool. It is clearing whole inventory.

function onClicked() 
for i=1, 1 do-----while wait(5) can allso be used and it is working (all other script that i tryed here seems not to work)
for i,v in pairs(game.Players:GetPlayers()) do 
    for a,b in pairs(v.Character:GetChildren()) do 
        if b:IsA("Tool") or b:IsA("HopperBin") then 
            b:Destroy()
        end
    end
    v.Backpack:ClearAllChildren()
end
    end
end
script.Parent.ClickDetector.MouseClick:connect(onClicked)

Is it possible to start script like this and continue writing so only the "Blue Master Key" gets removed from inventory?

function onClicked()
for i=1, 1 do
-------ADD CODE TO ONLY REMOVE "Blue Master Key" ---->

end
script.Parent.ClickDetector.MouseClick:connect(onClicked)

I realy aprishiate your help and time!
