Nissan Sentra Key Fob Battery Replacement (2007 – 2022)

Introduction

If you own a Nissan Sentra from 2007 to 2022, you might find yourself needing to replace the key fob battery. The process is straightforward and requires minimal tools. In this guide, I will walk you through the steps to change the battery in your key fob.

Whether you have a four, five, or even a six-button version of the key fob, the process remains the same. You will need a CR2032 coin battery and a flathead screwdriver.

Tools and Materials Needed

• CR2032 coin battery
• Flathead screwdriver

You can easily find the CR2032 battery online. I have provided a link to purchase it from Amazon for a good price. The flathead screwdriver should be small enough to fit into the key fob’s openings.

Step-by-Step Guide

Step 1: Remove the Internal Key

First, flip over your key fob. Hold down the small lever on the back of the device and pull out the internal key. This will give you access to the battery compartment.

Step 2: Open the Key Fob

Look at the bottom of the key fob. You will see an opening in the plastic. Insert your flathead screwdriver into this opening.

Push the screwdriver down into place and twist. As soon as you feel the key fob start to open, stop twisting. Work your way down the opening by inserting and twisting the screwdriver. This will help you avoid damaging the plastic.

Step 3: Access the Battery

Once the key fob is open, use the same flathead screwdriver to pry the old battery out. Insert the screwdriver under the corner of the battery and lift it up.

Take note of the battery type. You will need a CR2032 coin battery for the replacement.

Step 4: Insert the New Battery

When inserting the new battery, make sure the positive side (marked with a plus sign) is facing down. Push the battery into place.

Ensure the battery is securely fitted before proceeding to the next step.

Step 5: Reassemble the Key Fob

Line up the two halves of the key fob and squeeze them together until they snap into place. Reinsert the internal key by sliding it back into its slot.

Congratulations! You have successfully replaced the battery in your Nissan Sentra key fob.

Conclusion

Replacing the battery in your Nissan Sentra key fob is a simple task that you can do yourself. With just a CR2032 battery and a flathead screwdriver, you can save time and money by avoiding a trip to the dealership.
