Changing the battery
Flip key
- Open the flip blade. Never force the hinge sideways, since the spring and pin are the weak part of a flip key.
- Look along the edge for a notch. A coin turned in that notch usually separates the remote half from the blade half.
- Lift the cell out with a plastic tool and press in the new one with the + side matching.
- Press the halves together until no gap shows, then try every button.
A CR2450 is 24.5 mm across and 5.0 mm thick, much fatter than a CR2032. A thinner cell will rattle and lose contact, so buy the exact size.
Coin cells are a choking and burn hazard for children. Store the spares in their original pack, out of reach.
