How do I convert this old house lock script to FE?

I have a lock script here, but with FE it doesn't work.

function onButtonClicked()
local lock = game.Workspace:FindFirstChild("Home"..script.Parent.Parent.Parent.Parent.Parent.Name)
if not (lock) then
return
else
if script.Parent.Text == "Lock Doors" then
script.Parent.Text = "Unlock Doors"
lock.Home.FDoor.CanCollide = true
lock.Home.BDoor.CanCollide = true
lock.Home.GDoor.CanCollide = true
lock.Home.GarageDoor.Transparency = 0
lock.Home.GarageDoor.CanCollide = true
elseif script.Parent.Text == "Unlock Doors" then
script.Parent.Text = "Lock Doors"
lock.Home.FDoor.CanCollide = false
lock.Home.BDoor.CanCollide = false
lock.Home.GDoor.CanCollide = false
lock.Home.GarageDoor.Transparency = 1
lock.Home.GarageDoor.CanCollide = false
end
end
end
script.Parent.MouseButton1Click:connect(onButtonClicked)
