Gather Your Replacement Parts and Tools
Before you begin, you’ll only need one essential replacement part to get your key fob back in action:
- CR2032 3-volt coin cell battery – This is the standard battery size for most key fobs, including your 2015 Nissan Altima. You can find these widely available at most drug stores, hardware stores, and online retailers. Brands like Panasonic, Energizer, Duracell, and Sony all offer CR2032 batteries.
To ensure optimal performance and longevity, it’s always a good idea to check your Nissan Altima owner’s manual for the manufacturer’s recommended battery type. While CR2032 is the common type, confirming the OEM specification is a smart move.
In terms of tools, you’ll only need a single item:
- Small flathead screwdriver – A miniature flathead screwdriver, like those used for eyeglasses repair, is perfect for gently prying open the key fob casing.
Preparation is Key
To protect both your key fob and your work surface during the battery replacement, a little preparation goes a long way:
- Microfiber cloth – Wrap the tip of your flathead screwdriver with a thin microfiber cloth. This will prevent any scratches to the delicate electronic components inside the key fob and avoid marring the plastic exterior.
- Remove the key fob from your keyring – This will make handling the key fob easier and prevent accidental damage to your keys.
Understanding the Emergency Ignition Key
Every Nissan Altima key fob includes a hidden emergency metal key. This is a crucial feature, especially if your key fob battery dies unexpectedly when you’re away from home. This emergency key allows you to manually unlock your car door using a keyhole typically located on the underside of your driver’s side door handle.
Before you can access the battery compartment and perform the 2015 Nissan Altima key fob battery replacement, you’ll need to remove this emergency key. The following step-by-step instructions will guide you through the entire process.
Step-by-Step Guide to 2015 Nissan Altima Key Fob Battery Replacement
Follow these detailed steps to successfully 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.
-
Remove the Emergency Key: Locate the small release tab on the key fob. This tab is usually a small slider. Push the tab away from the center of the key fob. While holding the tab, gently pull the bottom edge of the key fob downwards. The emergency metal key should slide out easily. Set the emergency key aside in a safe place where you won’t misplace it.
-
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 should see small notches or grooves on the inside edge of the key fob casing. Carefully insert the tip of your microfiber cloth-covered flathead screwdriver into one of these notches. Gently twist or pry to separate the two halves of the key fob. If one notch doesn’t work easily, try the other. Once you have created a small opening, you should be able to carefully pull apart the top and bottom halves of the key fob casing. Remove the top half to expose the battery.
-
Replace the Old Battery: With the top half of the casing removed, you will see the old CR2032 battery. 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 upwards. Install the new CR2032 battery, ensuring the positive (+) side is facing up, matching the original orientation. Press the new battery firmly into place until it is secure.
-
Reassemble 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 securely closed.
-
Reinsert the Emergency Key: Slide the emergency metal key back into its slot until you hear or feel a click, indicating it is securely locked in place.
