Prepare Your Key Fob: Begin by placing your Nissan Altima 2015 key fob on a clean, flat surface with the buttons facing downwards. This orientation will help prevent any components from falling out during the process.

Remove the Emergency Key: Locate the small slider tab on your key fob. This tab is designed to release the mechanical emergency key housed within. Push the slider tab towards the edge of the key fob and simultaneously pull the bottom part of the key fob downwards. The emergency key should slide out easily. Set the emergency key aside in a safe place where you won’t misplace it. This emergency key is a crucial backup should your key fob battery completely fail before you replace it.

Open the Key Fob Casing: With the buttons now facing upwards and the emergency key removed, examine the slot where the key was located. You should see small notches along the bottom plastic edge of the key fob. These notches are your entry points to pry open the casing. Carefully insert the tip of your flathead screwdriver into one of these notches. Gently twist the screwdriver to separate the two halves of the key fob. If one notch is too tight, try the other. Work slowly and patiently to avoid cracking the plastic. Once you’ve created a small opening, you can usually use your fingers to carefully pull apart the top and bottom halves of the key fob completely.

Once the old battery is removed, take your new CR2032 battery and insert it into the battery compartment. Ensure the positive (+) side is facing upwards, matching the orientation of the old battery. Push the new battery firmly into place until it is securely seated.
