Changing the Battery in a Nissan Key Fob: A Quick and Easy Guide

A dead key fob battery can be a real pain, leaving you stranded and frustrated. But don’t worry, changing the battery in your Nissan key fob is usually a quick and easy DIY job. This guide will walk you through the process step-by-step, so you can get back on the road in no time.

What You’ll Need to Change Your Nissan Key Fob Battery

Before you begin, gather the following:

A small flat-head screwdriver (or a coin, depending on your key fob model).
A new CR2032 battery. This is the most common type of battery used in Nissan key fobs.
Optional: A small flashlight. This can be helpful if you’re working in a dimly lit area.

Step-by-Step Guide to Replacing Your Nissan Key Fob Battery

Here’s a general guide to changing the battery in your Nissan key fob. Keep in mind that the exact steps may vary slightly depending on the year and model of your vehicle. If you’re unsure about any of the steps, consult your owner’s manual or search for specific instructions for your Nissan model online.

1. Locate the Release Button or Notch: Examine your key fob and look for a small button or notch on the back or side. This is the release mechanism for the key fob housing.

2. Open the Key Fob: Use the flat-head screwdriver or a coin to gently pry open the key fob at the release point. You should hear a slight click when the housing separates. Be careful not to use excessive force, as this could damage the key fob.

3. Identify and Remove the Old Battery: Inside the key fob, you’ll see the battery. Carefully remove it, noting its orientation (positive (+) side up or down).

4. Insert the New Battery: Place the new CR2032 battery into the compartment, making sure it’s positioned the same way as the old battery.

5. Reassemble the Key Fob: Align the two halves of the key fob and press them together until you hear a click. This indicates that the housing is securely closed.

6. Test Your Key Fob: Ensure your key fob is functioning correctly by locking and unlocking your car doors and testing the remote start feature (if applicable).
