How to Change Your 2010 Nissan Altima Key Fob Battery

A dead key fob battery can be a real nuisance. Luckily, replacing the battery in your 2010 Nissan Altima key fob is something you can easily do at home. No need for a trip to the dealership! Just follow these simple steps:

What You’ll Need:

A new CR2025 battery (you can find these at most electronics stores, pharmacies, and online retailers)
A small flathead screwdriver or similar tool
Optional: A small container to hold the screws and components

Step-by-Step Guide:

Open the Key Fob: Locate the small notch or slot on the side of your key fob. Insert your flathead screwdriver into this slot and gently twist or pry to separate the two halves of the key fob casing. Be careful not to damage the plastic.
Locate the Battery: Inside the key fob, you’ll see the circular CR2025 battery. It’s usually held in place by a small clip or pressure.
Remove the Old Battery: Carefully use your flathead screwdriver to pry the old battery out of its compartment. Try to avoid puncturing the battery.
Install the New Battery: Insert the new CR2025 battery into the compartment, ensuring the positive (+) side faces upwards, just like the old battery. You should hear a small click when it’s properly seated.
Reassemble the Key Fob: Align the two halves of the key fob casing and press them together firmly until they snap back into place.
Test the Key Fob: Try locking and unlocking your car to make sure the new battery is working correctly.

Why Does My Key Fob Battery Die So Quickly?

Key fob batteries typically last between two and three years, but several factors can influence their lifespan. Frequent use, extreme temperatures, and even keeping your keys near electronic devices can drain your key fob battery faster.
