Changing the battery
Flip key
- Swing the key blade open first. On most flip keys the cell lives in the body behind the hinge.
- 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.
Smart key (push-button start)
- Start by freeing the hidden metal key: there is a latch or slide on the case, and the blade comes out once it moves.
- Look inside the empty key slot for a notch. Put the tip of the metal key or a small flat screwdriver wrapped in tape there and twist gently until the shell splits.
- Note which side of the old coin cell faces up (usually the side with the writing), lift it out with a plastic tool, and press the new one in the same way.
- Snap the halves back together, slide the metal key home, and press each button, then try the start button from the driver's seat.
On many recent GM smart remotes a button on the side releases the key; the slot at the bottom is where the case opens.
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.
