Hi dhphilly! I am very sorry for the issue you experienced in opening the battery cover on your remote. To remove the cover, push the rear cover open in the direction of the arrow at the bottom of the remote control. Grab the remote control with two hands,Then, push it forward with your thumbs. I hope this helps. For additional assistance, please contact Samsung customer support at 1-800-SAMSUNG, available 8AM - 12AM EST, 7 days a week, or Chat with us on Samsung.com: https://www.samsung.com/us/support/contact/
