That little red battery icon flashing on your Nissan's key fob is a gentle nudge to swap out the coin cell before it leaves you stranded. It usually lasts a couple of years, but when that warning appears, you have a few weeks of reliable operation left to find a CR2032. Popping the fob open with a flathead screwdriver is a simple fix, keeping your daily commute hassle-free.
