Gathering Your Supplies for Key Fob Battery Replacement
Before diving into the battery replacement, gather these minimal supplies. This ensures a smooth and efficient process.
Replacement Battery: The CR2032 Coin Cell
The heart of your key fob’s power lies in a small, readily available battery:
- 3-Volt Coin Cell Battery – CR2032: This is the specific battery type required for your 2015 Nissan Altima key fob. You can find CR2032 batteries at most drugstores, supermarkets, hardware stores, and online retailers. Brands like Panasonic, Energizer, Duracell, and Sony are all reliable options.
While any CR2032 battery will work, consulting your Nissan Altima owner’s manual is a good practice to identify the original equipment manufacturer (OEM) battery. For instance, your 2015 Altima might have originally come with a Panasonic CR2032. Using a similar quality battery can ensure optimal performance and longevity.
Tools: Simple and Effective
You won’t need a garage full of tools for this task. Just these two items will suffice:
-
Mini Flathead Screwdriver: A small flathead screwdriver, similar to what you’d use for eyeglasses repair, is ideal for gently prying open the key fob casing without causing damage.
-
Microfiber Cloth (Optional but Recommended): A thin microfiber cloth offers a protective layer. Wrapping the tip of your screwdriver with a microfiber cloth minimizes the risk of scratching the delicate electronic components inside the fob or marring the plastic exterior.
Preparation Steps Before You Begin
A little preparation goes a long way to ensure a hassle-free battery replacement.
- Protect Your Workspace: Choose a clean, flat surface to work on. This prevents losing any small parts and provides a stable base.
- Gather Your Tools and Battery: Have your CR2032 battery, screwdriver, and microfiber cloth (if using) within easy reach.
- Remove the Key Fob from Your Key Ring: Detaching the key fob from your keyring makes it easier to handle and prevents accidental damage to your keys.
Understanding the Emergency Ignition Key
Every Nissan Altima key fob, even with its advanced keyless entry system, includes a hidden emergency metal key. This ingenious feature ensures you’re never locked out of your vehicle should your key fob battery die unexpectedly. The door handle on your Altima has a discreet keyhole, usually located on the underside, where you can insert this emergency key for manual unlocking.
Before you can access the battery compartment for your 2015 Nissan Altima key fob battery replacement, you’ll need to remove this emergency key. The following step-by-step guide will detail exactly how to do this and proceed with the battery change.
Step-by-Step Guide: 2015 Nissan Altima Key Fob Battery Replacement

Remove the Emergency Metal Key: Locate the small slider tab on the key fob. It’s usually on the back or side of the fob. Push this tab towards the outer edge of the key fob.

Pry Apart the Key Fob Casing: Flip the key fob over so the buttons are facing upwards. Look into the slot where you just removed the emergency key. You should see small notches or a seam line on the plastic bottom edge of the fob within this slot. Carefully insert the tip of your mini flathead screwdriver (wrapped in a microfiber cloth if you’re using one) into one of these notches. Gently twist or pry to separate the two halves of the key fob casing. If it feels resistant, try the other notch. Once you find the right spot, the top half of the fob should detach. Remove the top half of the fob and set it aside.

Replace the Old Battery: With the top half of the fob removed, you’ll clearly see the CR2032 battery. Note the orientation of the battery (usually the positive (+) side facing upwards). Use your small flathead screwdriver to gently pry out the old battery. Be careful not to scratch any of the surrounding electronic components. Once the old battery is removed, insert the new CR2032 battery. Ensure the positive (+) side is facing upwards, matching the original battery’s orientation. Push the new battery firmly into place until it’s securely seated.

Reassemble the Key Fob: Carefully align the top and bottom halves of the key fob casing. Press them firmly together until they snap back into place. Ensure that the casing is flush on all edges, indicating it’s properly closed.
-
Reinsert the Emergency Key: Slide the metal ignition key back into its slot until you hear or feel a click. This confirms that the emergency key is securely locked in place.
-
Test Your Key Fob: Test the buttons on your key fob to ensure they are now working correctly. Try locking and unlocking your Nissan Altima remotely. If everything functions as expected, you’ve successfully completed your 2015 Nissan Altima key fob battery replacement!
