How to Change a Battery in Nissan Key Fob

A dead key fob battery can leave you stranded and frustrated. Don’t panic! Replacing the battery in your Nissan key fob is a quick and easy process you can do yourself. This guide will walk you through each step, empowering you to get back on the road in no time.

What You’ll Need:

  • A new CR2032 battery: These are readily available at most convenience stores, auto parts stores, and online.
  • A small flat-head screwdriver: This will help you to pry open the key fob casing.
  • Optional: A small container or tray: This will help to keep the small parts organized during the process.

Steps to Change the Battery:

  1. Identify the battery compartment: Most Nissan key fobs have a small release button or notch on the back. This is where you’ll start to separate the two halves of the key fob.

  2. Open the key fob: Gently insert the flat-head screwdriver into the notch or press the release button, while carefully prying the two halves of the key fob apart. Be careful not to use excessive force, as this could damage the casing.

  3. Remove the old battery: The old battery will be sitting in a designated slot. You can gently pry it out using your fingernail or the flat-head screwdriver. Take note of the battery’s orientation for installing the new one.

  4. Install the new battery: Place the new CR2032 battery into the slot, ensuring it’s facing the same direction as the old battery. Press down lightly until it snaps into place.

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

  6. Test the key fob: Once the key fob is back together, try locking and unlocking your car to ensure the new battery is working correctly.

Troubleshooting Tips:

If your Nissan key fob still doesn’t work after changing the battery, here are a few things to check:

  • Battery orientation: Double-check that you’ve installed the new battery with the positive (+) side facing up.
  • Battery contacts: Ensure the battery contacts inside the key fob are clean and free of debris. You can clean them gently with a cotton swab and rubbing alcohol.
  • Programming: In some cases, you may need to reprogram your key fob to your Nissan after changing the battery. Refer to your owner’s manual for specific instructions on how to do this.
