What Battery Does a 2014 Nissan Sentra Key Fob Use?

Step-by-Step Guide to Replacing Your 2014 Nissan Sentra Key Fob Battery
Replacing the battery in your 2014 Nissan Sentra key fob is a simple process that requires minimal tools. Here’s how to do it:
-
Prepare Your Workspace and Tools: Find a clean, well-lit area to work. Gather a new CR2032 battery and a small flathead screwdriver. Wearing latex or non-latex gloves is recommended to protect the electronic components from skin oils and static.
-
Locate the Emergency Key and Release: Flip your Nissan Sentra key fob to the back. You’ll see a small slider or button designed to release the mechanical emergency key. Slide or press this release and pull out the emergency key.
-
Access the Key Fob Casing: With the emergency key removed, look at the top of the key fob where the key was just removed. You should see a small notch or slot. This is where you’ll insert your flathead screwdriver to open the fob.
-
Carefully Separate the Fob Halves: Insert the tip of your flathead screwdriver into the notch. Gently twist the screwdriver. This should start to separate the two halves of the key fob casing. Work your way around the seam, gently prying until the case splits open. Avoid using excessive force, as you could damage the plastic casing.
-
Identify and Remove the Old Battery: Once the key fob is open, you’ll see the battery. It’s usually held in place by small clips. Note the orientation of the old battery – specifically, which side is facing up (+ or positive side). Use your flathead screwdriver to gently pry the old CR2032 battery out of its holder.
-
Insert the New CR2032 Battery: Take your new CR2032 battery and insert it into the battery compartment. Make sure the + (positive) side is facing down, matching the orientation of the battery you just removed. Press down gently until the new battery clicks securely into place.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing. Press them firmly together until they snap back into place. You should hear a click, indicating that the case is securely closed.
-
Replace the Emergency Key: Slide the emergency key back into its slot until it clicks and locks into position.
-
Test Your Key Fob: Try using your key fob to unlock your 2014 Nissan Sentra. It should now be working properly with the new battery.
