Press the Menu + Left (directional key) + Back buttons at once for 10 seconds. These are the steps for factory resetting of remote. After that is done the remote will pair with fire Tv device. If the remote doesn't pair automatically, press and hold the Home button for at least five seconds to make it discoverable so the device can try pairing again.
