To reset a Firestick remote, first unplug your Fire TV device from power for about 30 seconds. Then, remove the batteries from the remote. Press and hold the Home button on the remote for about 10–15 seconds. Release the button, reinsert the batteries, and turn your Fire TV back on. The remote should automatically reconnect. If it doesn’t, press and hold the Home button for 10 seconds again to pair it manually.
