How to Change a Nissan Key Fob Battery

A dead key fob battery can be a real pain, leaving you stranded and unable to unlock your Nissan. Thankfully, changing the battery is a quick and easy task you can do yourself without needing a trip to the dealership. This guide will walk you through everything you need to know about how to change a Nissan key fob battery, from choosing the right replacement to getting your key fob working like new again.

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

Before you begin, gather a few simple tools:

  • A new battery: The most common battery type for Nissan key fobs is a CR2032 3V lithium battery. You can find these at most supermarkets, electronics stores, and auto parts stores.
  • A small flathead screwdriver or a plastic pry tool: This will help you to carefully open the key fob casing.
  • Optional: A soft cloth or microfiber cloth: This will help to protect your key fob from scratches while you’re working.

Steps to Change Your Nissan Key Fob Battery

Once you have your tools ready, follow these simple steps:

  1. Identify the battery compartment: Examine your Nissan key fob. There is usually a small seam or groove running along the edge of the fob. This indicates the location of the battery compartment cover.

  2. Open the key fob: Carefully insert the tip of your flathead screwdriver or plastic pry tool into the seam or groove. Gently pry open the battery compartment cover. Avoid using excessive force, which could damage the fob.

  3. Remove the old battery: With the compartment open, you should see the old battery. Gently pry it out using your fingernail or the tip of your screwdriver. Note which side of the battery is facing up, as the new battery will need to be inserted in the same direction.

  4. Install the new battery: Align the positive (+) side of the new CR2032 battery with the positive (+) marking inside the battery compartment. Press down gently until the battery clicks into place.

  5. Reassemble the key fob: Align the battery compartment cover and press it firmly back into place until you hear a click, indicating it is secure. Test all buttons to ensure the new battery is working correctly.

Why is My Key Fob Not Working After Battery Change?

If you’ve followed these steps and your key fob is still not working, don’t panic! Here are a few things to check:

  • Battery installation: Double-check that the new battery is correctly installed with the positive (+) side facing up.
  • Battery contacts: Inspect the battery contacts inside the key fob for any dirt or corrosion. If necessary, clean them gently with a cotton swab and rubbing alcohol.
  • Key fob reprogramming: In rare cases, you may need to reprogram your key fob after changing the battery. Refer to your Nissan owner’s manual for specific instructions on how to do this.

“It’s always a good idea to have a spare key fob battery on hand,” says automotive electronics expert, John Miller, “That way, you’re prepared if your key fob battery dies unexpectedly.”
