We're grateful to have you here in the Roku Community, @Dianewood!
Thank you for letting us know about your Roku remote not working. We'd be happy to find the best resolution so you can return to utilizing your remote.
What specific Roku player are you having this issue with? Is this the remote that comes with your Roku player? Also, when you press random buttons on your remote, are there any blinking lights? If so, try resetting your remote by pressing and holding the Back and Home buttons simultaneously for about 20 seconds. After doing so, pair it again to see if this will make any difference.
We'll be looking forward to your response so we can assess your concern better and provide you with an accurate resolution.
Best regards,
Carly
