How would I track these both in one script?

So what I'm trying to make is make a script track 1) If the player is hovering over the brick and 2) If they pressed a key while hovering over that brick. Much appreciated.

local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()

Mouse.Move:connect(function()
    if Mouse.Target and Mouse.Target == workspace.Door1 then
       workspace.Door1.ekey.Enabled = true
		print("Im on it")
    elseif Mouse.Target and Mouse.Target ~= workspace.Door1 then
        workspace.Door1.ekey.Enabled = false
    end
end)

function onKeyDown(key)
			key = key:lower()
			if key == "e" and Mouse.Target == workspace.Door1 then
			print("E pressed over the brick")
		end	
	end
