Thanks for reaching out. Yes, it can work with HERO5 Black.
Power off your remote. Power ON your camera and set it up for pairing using the instructions here.
Now set your camera aside and pick up the remote.
With the remote powered OFF, press and hold the red Shutter button on the remote. While continuing to hold the red button, press the white Power button once briefly. The remote will power on and show two arrows moving towards each other. You can let go of the red button at this time. Now the remote is in pairing mode.
At this point, the camera and remote should both show arrows moving towards each other. After one minute or less, the camera and remote should pair.
