Keycard Door opens with the touch of the players parts? Why?

local TS = game:GetService("TweenService")

local hinge = game.Workspace.D1.Hinge
local key = script.Parent
local debounce = false

key.Touched:Connect(function(hit)
		local name = hit.Parent.Name
	if name == "Level 1 Keycard"  then
		script.Parent.Parent.neon.Color = Color3.new(1, 0, 0.0156863)
		wait(0.5)
		script.Parent.Parent.neon.Color = Color3.new(0.14902, 1, 0)
		return
	elseif name == "Level 2 Keycard" or "Level 3 Keycard" or "Level 4 Keycard" or "Level 5 Keycard" then
		if debounce == false then
			debounce = true
			local TSInfo = TweenInfo.new(2,Enum.EasingStyle.Linear, Enum.EasingDirection.In)
			local tweenanim = TS:Create(hinge, TSInfo, {CFrame = hinge.CFrame * CFrame.Angles(0, math.rad(90), 0)})
			wait(0.5)
			tweenanim:Play()
			wait(6)
			local newTSInfo = TweenInfo.new(2,Enum.EasingStyle.Linear, Enum.EasingDirection.In)
			local newanim = TS:Create(hinge, newTSInfo, {CFrame = hinge.CFrame * CFrame.Angles(0, math.rad(-90), 0)})
			wait(0.5)
			newanim:Play()
			wait(5)
			if debounce == true then
				debounce = false
			
			end
		end
	end
end)
	

why roblox?

Try Using if hit:IsA("Tool").
