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.
- Replace the cell, keeping the + side where it was, and check the small metal tab still touches it.
- Close the fob and test it. If it does not work, open it again and check the cell is seated flat.
A CR2025 is 20 mm across and 2.5 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.
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.
- Many key heads split along the side seam. Start at the small notch and pry a little at a time.
- Inside you may find a small circuit board in a tray. Lift the board out if the cell is underneath, swap the cell with the same side up, and refit the board.
- Close the head, check there is no gap, and try the buttons.
A CR1620 is 16 mm across and 2.0 mm thick. It is easy to confuse with the 20 mm CR20xx sizes, which will not fit.
Coin cells are a choking and burn hazard for children. Store the spares in their original pack, out of reach.
