How to Change Battery in My Nissan Key Fob

If you’re experiencing issues with your Nissan key fob, like decreased range or unresponsive buttons, a dead battery is likely the culprit. Luckily, changing your Nissan key fob battery is a quick and easy process you can do right at home. No need to visit a dealership or mechanic! This guide will walk you through each step, ensuring you’re back to using your key fob without a hitch in no time.

Identifying Your Nissan Key Fob Type

Before diving into the battery replacement, it’s essential to identify your specific Nissan key fob type. This will determine the battery you need and the exact steps involved. Here are the two most common types:

1. Traditional Key Fob with a Flip Key: This classic design features a physical key that flips out from the fob. It’s typically used in older Nissan models.

2. Smart Key Fob: This sleek and modern key fob often features a push-button start and may not have a visible physical key. It’s more common in newer Nissan models.

Once you’ve identified your key fob type, you can gather the necessary tools and proceed with the battery replacement.

What You’ll Need

A small flat-head screwdriver: This will be used to pry open the key fob casing.
A fresh CR2025 or CR2032 battery: The specific type depends on your Nissan key fob model. Consult your owner’s manual or check the existing battery for the correct type.

Steps to Change the Battery in Your Nissan Key Fob

Here’s a step-by-step guide on how to change the battery in your Nissan key fob:

For Traditional Key Fobs with a Flip Key:

Locate the small release button or notch on the back of the key fob. This button releases the physical key.
Press the release button and carefully slide the metal key out of the fob.
Identify the seam or groove running along the edge of the key fob.
Carefully insert the flat-head screwdriver into the seam and gently pry open the casing. Be cautious not to damage the internal components.
Locate the battery compartment and note the orientation of the battery (+/-).
Gently remove the old battery and replace it with the new one, ensuring the positive (+) and negative (-) sides match the previous orientation.
Align the key fob halves and press them firmly together until you hear a click, indicating the casing is securely closed.
Reinsert the metal key and test all the buttons on your key fob to ensure it’s functioning correctly.

For Smart Key Fobs:

Locate the small notch or indentation on the side or back of the key fob. This notch is usually designed for prying open the casing.
Carefully insert the flat-head screwdriver into the notch and gently twist or pry to separate the key fob halves. Be mindful not to use excessive force and damage the internal components.
Identify the battery, usually located within a dedicated compartment, and note its orientation (+/-).
Carefully remove the old battery and replace it with the new one, making sure the positive (+) and negative (-) sides match the previous orientation.
Align the key fob halves and press them firmly together until they snap back into place.
Test all the buttons on your key fob, including the proximity sensor, to ensure it’s working correctly.
