- The source for this row does not say which shape of key it is, so check your fob before you start.
- Find the seam and work it open slowly.
- Replace the cell with the same side up, close the case, and test.
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.
