I've helped quite a few people replace the battery in their Envision key fob, having done it several times myself. It's pretty straightforward but requires some care. The key fob usually has a snap-on design - just insert a small flathead screwdriver into the seam and gently pry it open, being careful not to use too much force to avoid damaging the plastic casing. Inside you'll find the small CR2032 coin battery, which might be held down by a metal clip. You can push it aside with your finger or tweezers to remove the battery. When reinstalling, make sure the battery's positive side faces upward, then align and snap the cover back into place. I recommend having a new CR2032 battery ready to avoid issues with old batteries leaking or being dead. Before starting, test your car's functions with the spare key to confirm it's a battery issue rather than a key fob malfunction. The whole process takes about a minute or two. For daily storage, keep your keys away from high-temperature environments to extend battery life.
