If it's a purple Roku Stick, replacement remotes simply aren't available. For the 3600 or later, you can still get a remote, but for only a little more than the cost of a remote you can get a brand new Roku player, which will be a much better working player than any early Stick model. The Roku Express 4K+ is currently on sale for $30, and it's a huge improvement over any Roku Stick, other than maybe the current model. But I think the 4K+ would be the smart choice.
