I never use :Clone(), I don't know how to use RemoteEvent to KeyDown events? Please make an example so a person can see in-game?
If you want everyone to see a clone, make a file in workspace named Clones then when you clone whatever you are cloning do this
local item = part:Clone() -- part = the part you are cloning item.Name = "Name" -- name of clone item.Parent = workspace.Clones
