Check the battery orientation in your Remote. Some require batteries pointing in the same direction, others in opposite directions. I don't know which applies to the Express remotes. With batteries out you'll probably see a battery placement diagram molded into the back of the battery chamber.

@makaiguy I have checked batteries sent with the remote and also new batteries that I purchased. They are in correctly. The remote doesn't show any lights at all when pressing buttons. I can't get past the language screen to use my remote on my phone. Thank you for your response. I appreciate you.
