Changing the battery
Separate remote fob
- This remote is its own fob, separate from the metal key, which makes it one of the easier ones to open.
- 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.
- Reassemble and test from a short distance.
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.
Coin cells are a choking and burn hazard for children. Store the spares in their original pack, out of reach.
