How to Change the Battery on a Nissan Key Fob

A dead key fob battery is never convenient, especially when you’re trying to get somewhere. Luckily, changing the battery in your Nissan key fob is a simple process you can do yourself in minutes. This guide will walk you through the steps for a variety of Nissan key fob models, helping you get back on the road quickly.

What You’ll Need to Change Your Nissan Key Fob Battery

Before you begin, gather the following items:

A new CR2032 battery (This is the most common type for Nissan key fobs, but it’s always a good idea to check your owner’s manual to confirm).
A small flat-head screwdriver or a plastic pry tool.

How to Identify Your Nissan Key Fob Type

Nissan has released many key fob styles over the years. Identifying your key fob type will help ensure you follow the correct instructions:

Standard Key Fob with Flip Key: This common type has a flip-out key blade and buttons on the side.
Smart Key/Proximity Key Fob: This type doesn’t have a visible key blade and allows keyless entry and start.
Intelligent Key: Similar to the Smart Key, it often has a panic button on the back.

Step-by-Step Guide to Changing Your Nissan Key Fob Battery

Follow the instructions for your key fob type:

Standard Key Fob with Flip Key (Example: 2014 Nissan Sentra)

Locate the release button on the back of the key fob. Press the button to release the metal key blade.
Insert the flat-head screwdriver or pry tool into the seam where the two halves of the key fob meet. Gently pry the two halves apart.
Carefully remove the old battery and note the orientation (+/-).
Insert the new battery, ensuring the positive (+) side faces up.
Align the two halves of the key fob and press firmly until you hear a click.
Test all buttons to ensure the new battery is working correctly.

Smart Key/Proximity Key Fob (Example: 2016 BMW i8 Key Fob)

Locate the small slot on the backside of the key fob.
Insert the flat-head screwdriver or a key into the slot and gently twist to release the emergency key blade.
Use the key blade or your fingernail to pry open the key fob at the seam created by the emergency key slot.
Carefully remove the old battery and note the orientation (+/-).
Insert the new battery, ensuring the positive (+) side faces up.
Align the two halves of the key fob and press firmly until you hear a click.
Test all buttons to ensure the new battery is working correctly.

Intelligent Key (Example: 2008 Ford Focus Key Fob Stopped Working)

Locate the small release button or notch on the back of the key fob.
Press the release button or insert a small flat-head screwdriver into the notch to release the emergency key blade.
With the key blade removed, you should see a small slot or indentation. Insert the flat-head screwdriver or pry tool into this slot and gently pry open the key fob.
Carefully remove the old battery and note the orientation (+/-).
Insert the new battery, making sure the positive (+) side is facing up as indicated.
Align the two halves of the key fob and press firmly until they snap back together.
Test all buttons to ensure the new battery is working correctly.

Tips and Troubleshooting

If your key fob still doesn’t work after replacing the battery, try reprogramming it to your car. You can usually find instructions in your owner’s manual or online.
If you’re uncomfortable changing the battery yourself, a dealership or automotive locksmith can do it for you.
