Gathering Your Tools and Materials

Changing the key fob battery requires minimal tools. You’ll need a small flat-head screwdriver or a similar tool to pry open the key fob casing.

Step-by-Step Guide: How to Change Battery in Nissan Maxima Key Fob

Here’s a detailed guide on how to change the battery in your Nissan Maxima key fob:

1. Locate the release button or slot: Examine your key fob carefully. There is usually a small button or slot on the side or back that allows you to separate the two halves of the key fob.
2. Insert the screwdriver: Gently insert the flat-head screwdriver into the release button or slot and apply slight pressure to pry open the key fob casing. Be careful not to damage the plastic.
3. Separate the key fob halves: Once the casing is open, carefully separate the two halves of the key fob to expose the battery compartment.
4. Remove the old battery: Identify the old CR2032 battery and gently pry it out of the compartment. You can use the flat-head screwdriver for this step as well.
5. Install the new battery: Insert the new CR2032 battery into the compartment, ensuring the positive (+) side is facing upwards, as indicated in the compartment.
6. Reassemble the key fob: Align the two halves of the key fob and press them together until they snap securely into place.
7. Test the key fob: Try locking and unlocking your car to verify the new battery is working correctly.

Common Problems and Troubleshooting

While replacing the key fob battery is usually straightforward, you might encounter some issues. If your key fob still doesn’t work after replacing the battery, try these troubleshooting tips:
