Hello, If the remote does not operate then you need to unplug the Roku from power, then plug it back in and let the remote "re-pair" (green light blinking on the remote). Try that and let me know what happens.
If that does not work, you may have received the remote with bad batteries, or you may need to perform a fresh reset of the Roku by pressing and holding the reset button on the back of the box, which requires you to run through the setup again.
