Is your 2018 Nissan Pathfinder key fob suddenly not working as reliably as it used to? Before you assume the worst, the most common culprit is often a simple fix: a dead battery. Replacing the battery in your Nissan Pathfinder key fob is a straightforward process you can easily do yourself, saving you time and money compared to dealership service. This guide will walk you through everything you need to know about your 2018 Nissan Pathfinder Key Fob Battery, including how to identify the right battery type and step-by-step instructions for replacement.
Identifying the Correct Battery for Your 2018 Nissan Pathfinder Key Fob
The key fob for your 2018 Nissan Pathfinder uses a common and readily available coin cell battery. Specifically, you’ll need a CR2032 battery. This 3-volt lithium battery is widely used in small electronic devices, including key fobs, watches, and calculators. You can purchase CR2032 batteries at most drugstores, supermarkets, electronics stores, and online retailers. It’s always a good idea to keep a spare CR2032 battery at home so you’re prepared when your key fob battery eventually needs replacing.
Step-by-Step Guide to Replacing Your 2018 Nissan Pathfinder Key Fob Battery
Replacing the battery in your 2018 Nissan Pathfinder key fob is a simple process that requires minimal tools. Here’s how to do it:
-
Gather your tools: You’ll need a small flathead screwdriver or a similar tool to gently pry open the key fob casing. You’ll also need a new CR2032 battery.
-
Locate the notch: On the side of your Nissan Pathfinder key fob, you’ll find a small notch or opening. This is where you’ll insert your flathead screwdriver.
-
Pry open the casing: Carefully insert the flathead screwdriver into the notch and gently twist. This should separate the two halves of the key fob casing. Avoid using excessive force to prevent damaging the plastic.
-
Remove the old battery: Once the casing is open, you’ll see the CR2032 battery. Take note of the battery’s orientation (+ side up). You can usually use your fingertip or the small screwdriver to gently pry the old battery out of its compartment.
-
Insert the new battery: Take your new CR2032 battery and insert it into the battery compartment, ensuring the + side is facing upwards, matching the orientation of the old battery.
-
Reassemble the key fob: Carefully snap the two halves of the key fob casing back together. You should hear a click indicating that they are securely closed.
-
Test your key fob: Press the buttons on your key fob to test if it’s working correctly. The doors should lock and unlock, and the remote start should function if your Pathfinder is equipped with it.

Troubleshooting Common Key Fob Battery Issues
After replacing the battery, your 2018 Nissan Pathfinder key fob should ideally work perfectly. However, if you still encounter issues, here are a few things to consider:
- Battery Orientation: Double-check that you inserted the new CR2032 battery with the correct polarity (+ side up). Incorrect orientation will prevent the key fob from working.
- Battery Quality: Ensure you are using a fresh, high-quality CR2032 battery from a reputable brand. Old or low-quality batteries may not provide sufficient power.
- Key Fob Damage: If your key fob has been dropped or damaged, internal components might be faulty. In such cases, battery replacement may not solve the problem, and you might need a new key fob.
- Programming Issues: While battery replacement usually doesn’t require reprogramming for basic functions like locking/unlocking, if you experience issues with remote start or other advanced features after battery replacement, it’s possible the key fob needs to be reprogrammed. This typically requires a visit to a Nissan dealer or a qualified automotive locksmith.
Where to Get a Replacement 2018 Nissan Pathfinder Key Fob if Needed
