How do you make a script where two parts collide, the object that is being collided will delete?

The object that is being hit is called 'dooropen' and the object that is colliding it is call 'goldkey'

I tried it right here

if goldkey:connected(function)("dooropen")
 then
script.Parent:Remove()

Part.Touched:connect.CanCollide = true

-- or nah

Why not a touched event?

script.Parent.Touched:connect(function(hit) hit:Destroy() end)
