Identifying the Correct Nissan Altima Key Fob Battery Size
For your Nissan Altima key fob, the battery you’ll need is a common and readily available 3-volt coin cell battery, specifically the CR2032. This Nissan Altima key fob battery size CR2032 is a standard for many key fobs and small electronic devices. You can find CR2032 batteries at most drug stores, hardware stores, and online retailers. Brands like Panasonic, Sony, Energizer, Maxell, and Duracell all offer this battery type.

While CR2032 is the standard Nissan Altima key fob battery size, it’s always a good idea to double-check your owner’s manual to confirm the manufacturer’s original equipment recommendation. For instance, your 2014 Nissan Altima’s original battery might have been a Panasonic CR2032. If you are unsure, don’t hesitate to consult your local Nissan dealership or a trusted service center.
Step-by-Step Guide to Nissan Altima Key Fob Battery Replacement
Replacing your Nissan Altima key fob battery is a simple process. Here’s what you’ll need and how to do it:
Tools You’ll Need:
- Small flathead screwdriver: A miniature screwdriver, like those used for eyeglasses repair, works perfectly for gently prying open the key fob.
Preparation:
- Microfiber cloth (optional): To prevent scratches, wrap the tip of your screwdriver with a thin microfiber cloth.
- Remove key fob from keyring: This makes handling the fob easier during the battery replacement process.
Understanding the Emergency Key:
Before we begin, it’s important to know that every Nissan Altima key fob includes a hidden emergency ignition key. This metal key ensures you can still access your vehicle even with a dead key fob battery. You’ll find a small keyhole on the underside of your car’s door handle for manual unlocking.
Battery Replacement Steps:
-
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 slider tab on the key fob. Push this tab towards the edge of the fob to release the metal emergency key. Once released, pull the bottom edge of the key fob downwards to slide the key out. Set the emergency key aside in a safe place.

- Pry Open the Key Fob: With the buttons facing up and the emergency key removed, look into the slot where the key was housed. You should see small notches on the plastic edge. Carefully insert your flathead screwdriver 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 have created a gap, carefully separate the top half of the fob from the bottom.

- Replace the Old Battery: With the top half of the fob removed, you will see the battery. Use your flathead screwdriver to carefully pry out the old CR2032 battery. Take note of the battery’s orientation – the positive (+) side should be facing upwards. Insert the new CR2032 battery, ensuring the positive (+) side is facing up. Push the new battery into place until it is secure.
