Changing a Battery in a Nissan Key Fob
Replacing the battery in your Nissan key fob is a simple task that you can usually do on your own without the need for special tools. Here is a step-by-step guide on how to change the battery. Before starting, ensure you have the correct replacement battery type, which is often a CR2025 or CR2032 3V coin battery. You can usually find the battery type listed in your owner’s manual or on the old battery itself once you open the key fob. Please note that these instructions are general and might vary slightly depending on the specific model or year of your Nissan vehicle.
Preparing to Change the Battery
Gather Materials
- Replacement battery (CR2025 or CR2032)
- Flathead screwdriver or a key fob opening tool
Finding the Right Replacement Battery
Consult your vehicle’s owner’s manual or look at the old battery after removal to find the correct replacement battery type for your Nissan key fob.
Step-by-Step Battery Replacement
Step 1: Open the Key Fob
Locate the small notch or indent along the seam of the key fob. Insert the flathead screwdriver into the notch and gently twist to pry apart the two halves of the key fob. Be careful not to apply too much force to avoid damaging the key fob.
Step 2: Remove the Dead Battery
Once the key fob is open, you should see the battery inside. Note how the battery is placed (which side is facing up) as you will need to place the new battery in the same orientation. Use the screwdriver to gently pry the dead battery out, taking care not to damage any internal components of the key fob.
Step 3: Insert the New Battery
Place the new battery into the battery compartment with the positive (+) side facing the correct direction according to your vehicle’s specifications. Ensure the battery sits snugly in its compartment.
Step 4: Close the Key Fob
Align the two halves of the key fob and gently press them together until they snap into place. You might hear a click sound confirming that the halves are securely fastened.
Step 5: Test the Key Fob
After you have changed the battery, it’s important to test the key fob to ensure it’s working properly. Press the buttons on the key fob and verify that the doors lock and unlock or the trunk opens as intended.
Troubleshooting
If your key fob is not functioning after the battery replacement:
- Double-check that the battery is inserted correctly with the positive side in the right orientation.
- Ensure that there is no plastic film on the battery that could be blocking the connection.
- Check the key fob for any visible damage or loose components.
- Consider checking the car’s manual for a key fob reset procedure if available.
Final Thoughts
Changing the battery in a Nissan key fob is typically a quick and easy process. If you’ve followed the steps correctly but the key fob still isn’t working, it’s possible the key fob itself might need to be reprogrammed, or there could be another issue at hand. For complex problems or if you’re uncomfortable changing the battery yourself, consult with a professional or your local Nissan dealership for assistance.
