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.
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.
Keep spare coin cells away from small children. A swallowed coin cell can burn the throat within hours; if it happens, go to an emergency room at once.
