Hi Lee! To replace the batteries in the remote, 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. Should you need additional assistance with this, please reach out to Samsung 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/
