how can i make this script have compatability with a tool?

i want code below to work with tools on the ground. (Like the cube doors from portal.)

script.Parent.Touched:connect(function()

    workspace.door1_level1.Transparency = 0.5
    workspace.door1_level1.CanCollide = false

end)



script.Parent.TouchEnded:connect(function()

workspace.door1_level1.Transparency = 0
    workspace.door1_level1.CanCollide = true
end)
