Why does this keycard script door unlock the door, but won't lock it again?

I'm trying to make a script where when a keycard is put in, it will unlock the door, and once put back in it will lock the door again. So far the script only locks the door, here's the snippet. Sorry if my code is messy:

script.Parent.Touched:Connect(function(hit)
	if hit then
		if hit.Parent and hit.Parent.ClassName == "Tool" then
			if Clearance[hit.Parent.Name] then
				if locked.Value == true then
					if debounce then
						debounce = false
						locked.value = false
						print(locked.Value)
						wait(.2)
						debounce = true
						end
					end
					elseif locked.Value == false then
						if debounce then
							debounce = false
							locked.Value = true
							print(locked.Value)
							wait(.2)
							debounce = true
						end
					end
				end
				end
			end)
