Step-by-Step Battery Replacement for Your 2018 Nissan Pathfinder Key Fob
Changing the battery in your Nissan Pathfinder key fob is a simple process, but it’s important to handle the internal components with care. To protect the key fob’s electronics, it’s recommended to wear gloves, such as latex or nitrile gloves, to prevent static discharge and keep the components clean. The 2018 Nissan Pathfinder key fob requires a CR2032 3V battery, widely available at most drugstores, supermarkets, and online retailers for a low cost, often under $5 for a multipack. You’ll also need a small flathead screwdriver to open the key fob casing.
-
Step 1: Access the Emergency Key. Turn your Nissan key fob over to the back. You’ll find a small slider or button designed to release the mechanical emergency key. Locate this release and activate it to remove the emergency key from the key fob.
-
Step 2: Locate the Key Fob Notch. Examine the top section of your key fob, where the key ring typically attaches. You should see a small notch or seam running along the edge where the front and back halves of the fob meet. This is where you’ll insert the screwdriver.
-
Step 3: Open the Key Fob Casing. Carefully insert the tip of your flathead screwdriver into the notch you located. Gently twist the screwdriver. This action should begin to separate the two halves of the key fob. Apply gentle pressure until the front and back pieces of the key fob come apart.
-
Step 4: Identify the Old Battery. Once the key fob is open, you’ll see the internal components. Locate the round, silver CR2032 3V battery. It’s usually held in place by small clips.
-
Step 5: Remove the Dead Battery. Use the flathead screwdriver to gently pry the old CR2032 battery out of its housing. Be careful not to damage the surrounding components. You can usually slip the screwdriver under the edge of the battery and gently lift it out.
-
Step 6: Insert the New Battery. Take your new CR2032 3V battery and insert it into the battery compartment. Ensure that the positive (+) side of the battery is facing down as you place it in.
-
Step 7: Secure the New Battery. Press down on the new battery until it clicks securely into place. You should feel it snap into the retaining clips.
-
Step 8: Reassemble the Key Fob. Carefully align the front and back halves of the key fob. Press them firmly together until they snap back into place. You should hear a click sound, indicating that the casing is securely closed.
-
Step 9: Reinsert the Emergency Key. Slide the emergency key back into its slot on the key fob until it clicks and locks into position.
-
Step 10: Test Your Key Fob. Try using your key fob to unlock your 2018 Nissan Pathfinder or start the ignition. If the battery replacement was successful, your key fob should now be working properly.
