Changing the battery

Separate remote fob

  1. This remote is its own fob, separate from the metal key, which makes it one of the easier ones to open.
  2. Find the slot along the edge and turn a coin in it. Go slowly so the clips do not snap.
  3. Swap the cell or cells, keeping the same side up as the old ones.
  4. Close the fob and test it. If it does not work, open it again and check the cell is seated flat.

This key takes two CR2016 cells. Change both at the same time and stack them the way the old pair sat; mixing a fresh cell with a tired one shortens the life of the new one.

A CR2032 is 20 mm across and 3.2 mm thick. CR2032, CR2025 and CR2016 share the same width but not the same thickness, so a swap between them can leave a loose contact or a case that will not close.

If a child might have swallowed a coin cell, treat it as an emergency and get to a hospital right away.
