How to change the battery on a Nissan key fob?

While changing out your Nissan model’s key fob battery is a straightforward process, it does involve touching sensitive and fragile electronics. To avoid damage to the key fob, make sure to wear a pair of gloves (latex or non-latex substitute). The Nissan key fob uses a CR2032 3V battery. You can usually get a multipack of these for under $5 USD. You’ll also need a small flathead screwdriver.
