Gather Your Supplies
Before you start, ensure you have everything you need for a smooth 2015 Nissan Altima key fob battery replacement. You won’t need many items:
Replacement Battery
- 3-volt coin cell battery – Part #CR2032. This is the standard battery for most key fobs of this type. You can find CR2032 batteries at most drugstores, hardware stores, and online retailers. Brands like Panasonic, Sony, Energizer, Maxell, and Duracell are all reliable options. To ensure you’re using the exact battery your Nissan originally used, check your owner’s manual. For instance, your 2014 Nissan Altima might have originally come with a Panasonic CR2032.
Tools
- Mini flathead screwdriver: A small screwdriver, like those used for eyeglasses repair, is ideal for gently prying open the key fob.
- Thin Microfiber Cloth (optional but recommended): This will protect your key fob from scratches during the opening process.
Preparation Steps
Before you begin the battery replacement:
- Protect the Fob: Wrap the tip of your flathead screwdriver with a thin microfiber cloth to prevent any scratches to the key fob or its internal components.
- Remove from Key Ring: Detach the key fob from your keyring for easier handling.
Understanding Your Emergency Ignition Key
Nissan smartly includes an emergency mechanical key within your key fob. This ensures you’re never locked out of your Altima due to a dead key fob battery. The door handle on your 2015 Nissan Altima has a hidden keyhole, usually on the underside, where you can insert this emergency key to manually unlock your car.
Before replacing the battery, you’ll need to remove this emergency key from the fob itself. The following steps will guide you through the entire Key Fob Battery 2015 Nissan Altima replacement process.
Step-by-Step Guide to Replace Your Key Fob Battery
Follow these instructions carefully to replace the battery in your 2015 Nissan Altima key fob:
Step 1: Position the Key Fob
Place the key fob on a flat surface with the buttons facing downwards.
Step 2: Remove the Emergency Key
Locate the small slider tab on the key fob. Push this tab towards the outer edge of the fob. While pushing the tab, gently pull the bottom edge of the key fob downwards. The metal emergency key should slide out. Set the key aside in a safe place.

Step 3: Open the Key Fob
Turn the key fob over so the buttons are facing upwards. Look into the slot where you just removed the emergency key. You’ll see two small notches on the plastic edge. Carefully insert your flathead screwdriver (tip covered with a cloth) into one of these notches. Gently twist or pry to separate the two halves of the key fob. If one notch is too tight, try the other. Once you create a small opening, you should be able to easily pull apart the top half of the fob.

Step 4: Replace the Old Battery
With the top half of the fob removed, you will see the CR2032 battery. Use your flathead screwdriver to gently pry out the old battery. Take note of the battery orientation – the positive (+) side should be facing up. Insert the new CR2032 battery, ensuring the positive side is facing upwards, matching the original orientation.
