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.
- Swap the coin cell, keeping the same face up as the one you removed, and do not bend the metal contact tab.
- Clip the body closed, fold the blade, and test the buttons from a few steps away.
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.
Keep spare coin cells away from small children. A swallowed coin cell can burn the throat within hours; if it happens, go to an emergency room at once.
