To replace the battery in your HD Series remote, you'll need a paperclip or similar.

  1. Insert the paperclip into the hole on the back of the remote and push. The battery/button assembly of the remote will pop out. 
  2. Use the paperclip to push the battery out of the battery clip. Note the orientation of the battery when removing it.
  3. Slide the new battery (CR2025) into the battery clip. The positive (+) side of the battery should face away from the PCB.
  4. The battery/button assembly is held in place with magnets, so once you've replaced the battery, slide it back into place.
