I recently noticed my Nissan Altima key fob was acting up and realized it might be time to change the battery. I wanted to share some info and seek advice or tips on doing this without causing any issues.

What you need:

  • Replacement battery: Most Nissan Altima key fobs use either a CR2025 or CR2032 battery. It’s a good idea to check your specific model to be sure.
  • Small screwdriver: Typically a flathead or a small Phillips screwdriver will do the trick.
  • A clean space: Make sure you’re working on a flat surface to avoid losing any small components.

Steps to replace the battery:

  1. Open the key fob: Use the screwdriver to gently pry apart the fob. Be careful not to damage the casing.
  2. Remove the old battery: Take note of how the old battery is positioned (which side is positive) before removing it to ensure you place the new one correctly.
  3. Insert the new battery: Place the new battery in the same position as the old one.
  4. Reassemble the fob: Press the two halves of the fob back together until they click securely.

Troubleshooting tips:

  • If your key fob still isn’t working after changing the battery, try re-syncing it with your car. Instructions can usually be found in the owner’s manual.
  • Check for any corrosion on the battery contacts or inside the fob.

Final thoughts:

If you’ve done this before, any extra tips or tricks would be greatly appreciated! Also, if anyone has suggestions on where to buy a compatible battery for the best price, that would help a lot! Thanks in advance!

Yeah, I feel that sometimes the rubber buttons can get stuck if you’re not careful. Just be gentle when you close it. Any other tips for keeping the buttons in good shape?

Always use battery retaining clips if your model has them—they can be easy to miss! The last thing you want is a battery rattling around inside your fob. :smile:

Good point! I replaced mine from a model that had none, and it worked fine. But I can see how it could be a fiasco if there were clips involved.
