Experiencing a finicky Nissan Altima key fob? Before you schedule a service appointment, the culprit might be something as simple as a dying battery. Luckily, replacing the battery in your Nissan Altima key fob is a quick and easy process you can do yourself at home with just a few tools. This guide will walk you through each step, from identifying the right replacement battery to getting your key fob back in working order.
What You’ll Need:
- A new CR2032 battery (the most common type for Nissan Altima key fobs)
- A small flathead screwdriver or a plastic pry tool
- Your Nissan Altima key fob
Steps to Change the Battery in your Nissan Altima Key Fob:
-
Locate the release button: Examine your Nissan Altima key fob. There’s a small release button, usually on the back, that you’ll need to press to access the battery compartment.
-
Open the Key Fob: While pressing the release button, gently separate the two halves of the key fob. You might need to use a bit of force, but be careful not to damage the casing.
-
Remove the Old Battery: Once the key fob is open, you’ll see the battery. Carefully remove it, noting which side was facing up. This will help you position the new battery correctly.
-
Insert the New Battery: Place the new CR2032 battery into the compartment, making sure it’s oriented the same way as the old one (positive side up).
-
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 key fob is securely closed.
-
Test the Key Fob: Try locking and unlocking your car doors using the key fob. If the buttons work, you’ve successfully replaced the battery!
Troubleshooting Tips:

Key Fob Still Not Working? If you’ve replaced the battery and your key fob is still unresponsive, there could be other issues at play, such as:
- Programming Issues: The key fob might need to be reprogrammed to your Nissan Altima. Check your owner’s manual or contact a certified Nissan dealer or automotive locksmith for assistance. For more information on programming, see our guide on how to program a dodge key fob.
- Internal Key Fob Damage: Physical damage or water exposure could impact the key fob’s circuitry. Consider consulting with a professional for diagnosis and repair.
- Car Battery Issues: In rare cases, a weak or dead car battery can interfere with the key fob’s signal. Ensure your Nissan Altima’s battery is in good working order.
-
Key Fob Range is Limited? If your key fob works but has a shorter range than usual, try these solutions:
- Reposition Yourself: Obstacles or interference can weaken the signal. Try moving closer to your car or to a more open area.
- Check for Interference: Electronic devices like cell phones or laptops can interfere with the key fob signal.
- Replace the Battery (Again): Even new batteries can be faulty. Try a different CR2032 battery to rule this out.
