Android boxes don't work the same as other components in terms of the remote. You won't find a code to make it work. You can pair via Bluetooth or rf but no universal as far as I know. Best bet is to be lucky enough that the device is hdmi-cec compliant. Check HDMI settings in box. If it is then check TV also, if it is (most newer sets are) then you should be able to use the TV remote to control the box (at least the Kodi install). Unless you are using Google TV my guess is that you need an air mouse or keyboard to navigate your box.
