Replacing the battery is a simple process. Here’s a step-by-step guide to help you:
-
Locate the Release Latch: On your Nissan Maxima key fob, you’ll find a small latch. This latch releases the physical key that slides into the fob.
-
Remove the Physical Key: Slide the latch to release and remove the physical key from the key fob. This will reveal slots that will help you open the fob casing.

Open the Key Fob Casing: With the key removed, you’ll see small slots exposed on the key fob. Insert a small flathead screwdriver into one of these slots. Gently twist the screwdriver. This action will separate the two halves of the key fob casing.

Pro Tip: While some people pry the fob open from the side slots, using the slots revealed after key removal can help prevent damage and distortion to the sides of your key fob, keeping it looking its best.
-
Access the Battery: Once the fob is open, you’ll see the CR2032 battery. It’s usually held in place by small clips.
-
Remove the Old Battery: Carefully remove the old battery. Note the orientation of the battery before removing it – usually, the positive (+) side is facing up.
-
Install the New Battery: Place the new CR2032 battery into the compartment. Ensure you install it with the same orientation as the old battery, typically with the face of the battery (the side with writing) facing down when installed in the fob. This means the information on the battery face will be hidden once installed, and only the blank bottom of the battery will be visible.
-
Close the Key Fob Casing: Carefully snap the two halves of the key fob casing back together until they are securely closed. You should hear a click or feel them snap into place.
-
Reinsert the Physical Key: Slide the physical key back into the key fob until it locks into position.
After replacing the battery, your 2011 Nissan Maxima key fob should be working correctly again.
Troubleshooting: What If New Batteries Don’t Solve the Problem?
In most cases, replacing the CR2032 battery will resolve issues with your key fob. However, if you find that both of your key fobs are suddenly showing as “low battery” or not working even after replacing the batteries, there might be a different issue.
As mentioned in the original context, a less common but possible problem could be related to the intelligent key system antennas in your Nissan Maxima. Your vehicle relies on antennas to communicate with the key fob. If one of these antennas is malfunctioning, it could lead to issues with key fob recognition, even with fresh batteries.
If you suspect an antenna problem, it’s best to seek assistance from a qualified and knowledgeable automotive service technician. Diagnosing and repairing issues within the intelligent key system requires specialized expertise and equipment.
In Conclusion
Replacing the battery in your 2011 Nissan Maxima key fob is a simple maintenance task that can often resolve issues with key fob functionality. By using the correct CR2032 battery size and following these easy steps, you can quickly get your key fob working again. Remember to handle the internal components with care and if problems persist after battery replacement, consider seeking professional help to diagnose potential issues with your vehicle’s intelligent key system.
