What You’ll Need for Your Nissan Key Fob Battery Change
Before you begin, gather these simple items:
Replacement Battery
- 3-Volt Coin Cell Battery – CR2032: This is the standard battery for most Nissan key fobs. You can find CR2032 batteries at most drugstores, hardware stores, and online retailers. Brands like Panasonic, Sony, Energizer, Maxell, and Duracell are all reliable options. To ensure you’re using the correct battery, check your Nissan owner’s manual. It may specify the original equipment manufacturer (OEM) battery, such as Panasonic CR2032 for a 2014 Nissan Altima.
Tools
- Small Flathead Screwdriver: A mini flathead screwdriver, similar to what you would use for eyeglasses repair, is ideal for gently prying open the key fob.
- Microfiber Cloth (Optional): Using a thin microfiber cloth to cover the screwdriver tip can help prevent scratches on the key fob casing.
Preparing for Your 2015 Nissan Key Fob Battery Replacement
Before starting the battery replacement:
- Protect the Fob: If you’re using a screwdriver, consider wrapping the tip with a microfiber cloth to minimize any potential scratches to the key fob or its internal components.
- Detach from Keyring: Remove the key fob from your keyring to make it easier to handle during the battery replacement process.
Understanding the Emergency Ignition Key
Nissan key fobs include a hidden emergency metal key. This key is a crucial backup in case your key fob battery dies when you are away from home. The emergency key allows you to manually unlock your car door. You’ll find a small keyhole on the underside of your car’s door handle. Familiarize yourself with this feature before you need it!
Let’s get started with the battery replacement. The first step is removing this emergency key.
Step-by-Step Guide: Replacing Your 2015 Nissan Key Fob Battery
Follow these steps carefully to replace your 2015 Nissan Altima key fob battery:
-
Position the Key Fob: Place the key fob on a flat surface with the Nissan buttons facing downwards.
-
Remove the Emergency Key: Locate the small release tab on the key fob. Push this tab towards the edge of the fob. While pushing the tab, gently pull down on the bottom edge of the key fob. The metal ignition key should slide out. Set the emergency key aside in a safe place.
-
Open the Key Fob Casing: With the buttons still facing down, look into the slot where you removed the emergency key. You will see two small notches on the lower plastic edge of the fob. Carefully insert your flathead screwdriver 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. Remove the top half of the fob to expose the battery compartment.
-
Replace the Old Battery: Once the top half is removed, you will see the CR2032 battery. Use your small flathead screwdriver to carefully pry out the old battery. Be gentle to avoid scratching any of the internal components. Take note of the battery 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.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob – the front and back covers. Gently press them together until they snap securely back into place. Ensure that all edges are flush and properly closed.
-
Reinsert the Emergency Key: Slide the metal ignition key back into its slot until you hear or feel it click securely into position.
Your 2015 Nissan Key Fob Battery replacement is now complete! Test your key fob to ensure it is working correctly.
