Changing the battery
Separate remote fob
- A separate fob has no key blade inside, so it opens with nothing but a coin or a small screwdriver.
- Find the slot along the edge and turn a coin in it. Go slowly so the clips do not snap.
- Swap the cell or cells, keeping the same side up as the old ones.
- Close the fob and test it. If it does not work, open it again and check the cell is seated flat.
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.
Flip key
- Swing the key blade open first. On most flip keys the cell lives in the body behind the hinge.
- Look along the edge for a notch. A coin turned in that notch usually separates the remote half from the blade half.
- Swap the coin cell, keeping the same face up as the one you removed, and do not bend the metal contact tab.
- Clip the body closed, fold the blade, and test the buttons from a few steps away.

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