Key with remote in the head
- The remote electronics sit in the plastic head of the key itself, so there is no separate fob to open.
- Find the seam around the head. Twist a coin or small flat screwdriver in the notch at the blade end or side until the halves part.
- The coin cell is usually under or on the back of a small board. Keep the rubber button pad in place while you swap the cell.
- Close the head, check there is no gap, and try the buttons.
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.
