A Nissan key fob is a convenient tool that allows you to lock, unlock, and start your car remotely. Over time, the battery inside the key fob will drain, causing it to become less responsive or stop working altogether. Changing the battery is an easy task you can do yourself with minimal tools. This guide will walk you through how to replace the battery in your Nissan key fob quickly and safely.
What You’ll Need
- A replacement battery (usually a CR2032 or CR2025 coin cell battery; check your owner’s manual or existing battery for the correct type)
- Small flathead screwdriver or a plastic pry tool
- Clean cloth (optional)
Step-by-Step Instructions
1. Prepare Your Workspace
- Find a clean, flat surface to work on.
- Have good lighting to see small parts clearly.
2. Remove the Mechanical Key
- Locate the small release latch or button on the key fob.
- Slide or press it to remove the mechanical key from the fob.
3. Open the Key Fob Case

4. Remove the Old Battery
- Locate the battery inside the fob.
- Use the screwdriver or your fingernail to carefully pop out the old battery.
- Take note of the battery’s orientation (which side is facing up) to ensure you install the new one correctly.
5. Insert the New Battery

6. Reassemble the Key Fob
