I want this door to only open with a keycard, it opens with an arm though. How to fix?

The door is supposed to only open when the keycard touches, but it's also opening with a player's arm. How do I stop this? Here is the script:

                            --<tkcmdr>--

local door = script.Parent
local bool = true
local bool2 = true
local clearance = {
    ["Omni"] = true,
    ["MTF"] = true,
    ["L5"] = true, 
    ["L4"] = true,
    ["L3"] = true,
    ["L2"] = true,
    ["L1"] = false,
}

function openDoor()
    script.Parent.DoorOpen:play()
    for i = 1,(door.Size.z / 0.30) do
        wait()
        door.CFrame = door.CFrame - (door.CFrame.lookVector * 0.30)
    end
    wait(3)
    script.Parent.DoorClose:play()
    for i = 1,(door.Size.z / 0.30) do
        wait()
        door.CFrame = door.CFrame + (door.CFrame.lookVector * 0.30)
    end
end

script.Parent.Parent.KeycardReader1.touched:connect(function(touch)
    if touch.Name == "Handle" and clearance[touch.Parent.Name] and bool then
        bool = false
        script.Parent.AccessGranted:play()
        script.Parent.Parent.Light1.brickColor = BrickColor.new("Bright green")
        script.Parent.Parent.Light2.brickColor = BrickColor.new("Bright green")
        openDoor()
        wait(1)
        script.Parent.Parent.Light1.brickColor = BrickColor.new("Bright red")
        script.Parent.Parent.Light2.brickColor = BrickColor.new("Bright red")
        bool = true
    elseif touch.Name == "Handle" and not clearance[touch.Parent.Name] and bool2 then
        bool2 = false
        script.Parent.AccessDenied:play()
        wait(1)
        bool2 = true
    end
end)

script.Parent.Parent.KeycardReader2.touched:connect(function(touch)
    if touch.Name == "Handle" and clearance[touch.Parent.Name] and bool then
        bool = false
        script.Parent.AccessGranted:play()
        script.Parent.Parent.Light1.brickColor = BrickColor.new("Bright green")
        script.Parent.Parent.Light2.brickColor = BrickColor.new("Bright green")
        openDoor()
        wait(1)
        script.Parent.Parent.Light1.brickColor = BrickColor.new("Bright red")
        script.Parent.Parent.Light2.brickColor = BrickColor.new("Bright red")
        bool = true
    elseif touch.Name == "Handle" and not clearance[touch.Parent.Name] and bool2 then
        bool2 = false
        script.Parent.AccessDenied:play()
        wait(1)
        bool2 = true
    end
end)
