Understanding Your Nissan Altima Key Fob Battery
Your Nissan Altima’s key fob is a marvel of modern technology, allowing you to lock, unlock, and even start your car remotely. However, this convenience relies on a small battery inside the key fob. Over time, this battery will deplete, leading to decreased range or even a completely unresponsive key fob.
Several signs might indicate your Nissan Altima key fob battery needs replacing:

- Intermittent Functioning: The key fob works sometimes but not others.
- No Response: The key fob doesn’t respond at all.
- Dashboard Warning: Some Altima models display a “Key Fob Battery Low” warning on the dashboard.
Choosing the Right Battery for your Nissan Altima Key Fob
Nissan Altima key fobs typically use a CR2025 or CR2032 battery. The exact type can vary depending on the model year of your Altima. To be absolutely certain, consult your owner’s manual or look for markings on your existing battery.
Here are some tips for purchasing a replacement battery:
- Reputable Brands: Choose batteries from well-known brands like Duracell, Energizer, or Panasonic to ensure quality and longevity.
- Freshness: Check the battery’s expiration date to ensure it’s fresh and has the longest possible lifespan.
- Online Retailers: Online retailers often offer competitive prices on batteries, making it convenient to find the best deal.
How to Change the Battery in your Nissan Altima Key Fob
Changing the battery in your Nissan Altima key fob is a simple process that you can easily do yourself.
