Trying to trigger this function. Will someone tell me how to call this function correctly?

I'm making a keycard so when it touches the keycardblock it calls a function (no errors in the output). It would be nice if someone could suggest a efficient way to trigger this function, I did the best I could but nothing happens.

local KeyCardBlock = game.workspace.KeyCardBlock
local KeyCard = game.workspace.KeyCard
local SoundFolder = game.workspace.SoundFolder

KeyCardBlock.thing.Touched:Connect(function()
	if Tool.Parent == game.StarterPack then
		local keycardcall = 'key card used'
		print (keycardcall)
		---write function for whatever block is changed by this
	end

	if KeyCard.Parent == game.workspace
		local deny = 'Key card denied.'
		print (deny)
		SoundFolder.TemporarySound.Playing = true
		wait (3)
		SoundFolder.TemporarySound.Playing = false --Sound must be updated

	end
end)

I'm trying to make the computer check whether the keycard is in the StarterPack. It doesn't work when I walk right up to the key card machine and then the transparent 'thing' which should call the function.

I tried make it so it would check if you have the key card. It obviously didn't work.
