Why Replace Your Key Fob Battery?
A key fob battery is essential for the remote functions of your vehicle, including locking and unlocking doors, remote start, and activating the alarm. As the battery weakens, you may notice decreased range, requiring you to be closer to your car for the fob to work. In extreme cases, the key fob might stop working altogether. Replacing the battery promptly ensures you avoid the inconvenience of manual entry and maintain full access to your vehicle’s features.
What You’ll Need for a 2015 Altima Key Fob Battery Replacement
Before you begin, gather these simple items:
- Replacement Battery: You’ll need one 3-volt coin cell battery, specifically the CR2032 model. This battery type is widely available at drugstores, hardware stores, and online retailers. Brands like Panasonic, Energizer, and Duracell are all reliable options. Consult your owner’s manual for the original equipment manufacturer’s recommendation if you prefer.
- Mini Flathead Screwdriver: A small, eyeglass repair-sized flathead screwdriver is perfect for gently prying open the key fob casing without causing damage.
- Microfiber Cloth (Optional): Using a thin microfiber cloth to cover the tip of your screwdriver can prevent scratches to the key fob’s plastic or internal components.

Step-by-Step Guide: Replacing Your 2015 Nissan Altima Key Fob Battery
Follow these detailed steps to replace your 2015 Altima Key Fob Battery:
Step 1: Prepare Your Workspace
Find a clean, flat surface to work on. This will prevent parts from rolling away and provide a stable base for disassembling and reassembling the key fob.
Step 2: Remove the Emergency Key
Every Nissan key fob includes a mechanical emergency key for manual door unlocking. Locate the small release tab on your key fob. It’s usually a small button or slider. Press and hold or slide this tab to release the metal ignition key. Gently pull the key out and set it aside in a safe place.

Step 3: Open the Key Fob Casing
With the emergency key removed, look into the slot where the key was housed. You’ll notice small notches or seams on the edge of the key fob casing. Position the key fob with the buttons facing upwards. Carefully insert the tip of your flathead screwdriver (preferably covered with a microfiber 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. Work slowly and carefully to avoid cracking the plastic.

Step 4: Remove the Old Battery
Once the key fob is open, you’ll see the CR2032 battery. It might be held in place by small clips. Use your flathead screwdriver to gently pry the old battery out of its compartment. Take note of the battery’s orientation – usually, the positive (+) side faces up.
Step 5: Install the New Battery
Insert the new CR2032 battery into the compartment, ensuring the positive (+) side is facing upwards, matching the orientation of the old battery. Press down firmly until the battery is securely in place.
Step 6: Reassemble the Key Fob
Carefully align the two halves of the key fob casing. Press them firmly together until they snap back into place. Ensure there are no gaps and the casing is securely closed.
Step 7: Test Your Key Fob
Insert the emergency key back into the key fob until it clicks securely. Test the key fob’s functions by pressing the lock, unlock, and other buttons to confirm it’s working correctly.
