Changing the battery
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.
- Work a thin flat tool into the seam near the blade and twist; go round slowly if it does not open at once.
- 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.
This key takes two CR2025 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.
Coin cells are a choking and burn hazard for children. Store the spares in their original pack, out of reach.
