How to contact support for a replacement remote - mine was defective out of the box
Just received my Roku Express from Amazon today. About pulled my hair out trying to figure out why it wasn't working. I replaced cables, batteries, restarted, reset.... everything. Finally, I dug around and found the remote from my original Roku (from maybe 10 years ago). And it worked. But that old remote has to be held together with duct tape... and I paid for a new one. So, how do I get Roku to send me a new one? Pulling my hair out again... but this time trying to find a way to contact them and keep getting sent here. Now that I have it set up and activated, I really don't want to return the whole device to Amazon. (Note: I did the cell phone camera test... and there is no IR light on the new remote, but I see it on the ancient remote.)
You really have to deal with Amazon before you deal with Roku. What's the model number of your Roku displayed under Settings->System->About? If it's an Express 4k+ then it comes with a Wi-Fi direct remote that requires pairing. If there's a button in the battery compartment then it's one of those.
For the record:
