Gathering Your Supplies for a Smooth Replacement
Before you begin, you’ll need to gather just a couple of items to make the 2015 Nissan Altima key fob battery replacement process as smooth as possible.
The Essential Replacement Part: Battery Type
The only part you’ll need is a new battery. It’s crucial to use the correct type to ensure proper function. For your 2015 Nissan Altima key fob, you need a:
- 3-volt coin cell battery – Part #CR2032
This CR2032 battery is widely available. You can find it at most drugstores, hardware stores, and online retailers. Brands like Panasonic, Energizer, Sony, Duracell, and Maxell all offer this common battery type. While any CR2032 battery will work, consulting your Nissan Altima owner’s manual is always a good idea to confirm the original equipment manufacturer (OEM) battery if you prefer to stick with the same brand.
Simple Tools for the Job
You likely already have the necessary tool at home:
- Mini flathead screwdriver: A small, eyeglasses-repair-sized flathead screwdriver is perfect for gently prying open the key fob casing.
Preparation for Protection
To prevent any scratches or damage during the battery replacement:
- Thin microfiber cloth: Placing a microfiber cloth over the tip of your screwdriver will protect the key fob’s plastic casing from scratches as you pry it open.
- Remove the key fob from your keyring: This will give you more room to maneuver and prevent accidental damage to your keys.
Understanding Your Emergency Ignition Key
Before we dive into the battery replacement, it’s important to know about the emergency metal key hidden within your 2015 Nissan Altima key fob. This key is a lifesaver if your key fob battery dies unexpectedly, ensuring you’re never locked out of your vehicle.
Your Altima’s door handle has a hidden keyhole, usually on the underside. If your key fob stops working, you can use this emergency key to manually unlock your car door.
Now, let’s get to the battery replacement process! The first step is to remove this emergency key from the fob itself.
Step-by-Step Guide to 2015 Nissan Altima Key Fob Battery Replacement
Follow these detailed steps to replace the battery in your 2015 Nissan Altima key fob:
-
Position the Key Fob: Place your Nissan Altima key fob on a flat surface with the buttons facing downwards.
-
Release and Remove the Emergency Key: Locate the small slider tab on the key fob. Push this tab towards the edge of the fob, away from the metal key ring loop. While pushing the tab, gently pull the bottom edge of the metal key downwards. The emergency key should slide out. Set the key aside in a safe place where you won’t lose it.
-
Prying Open 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’ll see small notches on the inside plastic edge of the fob. Carefully insert the tip of your flathead screwdriver (covered with a microfiber cloth) into one of these notches. Gently twist the screwdriver to pry the two halves of the key fob apart. If one notch is too tight, try the other. Once you create a small opening, you can usually separate the two halves by hand. Remove the top half of the key fob casing.
-
Replacing the Old Battery: With the top half of the casing removed, you will now see the CR2032 battery. Note the orientation of the battery (usually the positive side with the “+” symbol facing up). Use your small flathead screwdriver to gently pry the old battery out of its housing. Be careful not to scratch any of the surrounding electronic components. Take your new CR2032 battery and push it into place, ensuring the positive (+) side is facing upwards, matching the original orientation. It should snap in securely.
-
Reassembling the Key Fob: Carefully align the two halves of the key fob casing. Press them firmly together until they snap back into place, ensuring all edges are flush and closed tightly. Finally, slide the emergency metal ignition key back into its slot until you hear or feel it click securely.
You’re All Set!
Congratulations! You’ve successfully completed the 2015 Nissan Altima key fob battery replacement. Your key fob should now be working perfectly. This simple maintenance task can save you time and money compared to visiting a dealership for a battery replacement.
