Is your Nissan key fob refusing to unlock your car doors? You’re likely facing a common issue: a dead battery. Don’t worry, this isn’t a trip to the dealership situation. Replacing the battery in your Nissan key fob is a surprisingly simple task you can handle yourself in just a few minutes. This guide will walk you through each step to get your key fob working again quickly and efficiently.
What You’ll Need to Replace Your Nissan Key Fob Battery
Before you begin, gather these few items to make the process smooth:
- New CR2032 3V Battery: This is the standard battery for most Nissan key fobs. You can find these at most drugstores, supermarkets, and online retailers for a few dollars. Buying a multipack is a good idea to have spares on hand.
- Small Flathead Screwdriver: A small, precision flathead screwdriver is ideal for gently prying open the key fob.
- Latex or Non-latex Gloves (Optional): While not essential, wearing gloves can prevent transferring oils from your fingers to the sensitive electronic components inside the key fob.
Step-by-Step Guide to Nissan Key Fob Battery Replacement
Follow these detailed steps to replace your Nissan key fob battery:
-
Access the Emergency Key: Flip your Nissan key fob over to the back. You’ll see a small slider or button designed to release the emergency mechanical key. Locate this and move the slider to unlock and remove the emergency key. Set the metal key aside in a safe spot.
-
Locate the Fob Notch: Examine the top edge of your key fob, where the key ring is typically attached. 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.
-
Carefully Separate the Fob Halves: Insert the tip of your flathead screwdriver into the notch. Gently twist the screwdriver. You should feel the key fob begin to separate. Work your screwdriver around the seam, carefully prying until the front and back halves of the fob come apart. Avoid using excessive force to prevent damage to the plastic casing.
-
Identify the Old Battery: Once the fob is open, you’ll see the internal components and the round, silver CR2032 battery nestled in a small compartment within the back half of the fob.
-
Remove the Dead Battery: Use the flathead screwdriver to gently pry the old battery out of its housing. You can usually slip the screwdriver under the edge of the battery and lift upwards. Take note of the battery’s orientation – specifically which side is facing up (+ side).
-
Insert the New Battery: Take your new CR2032 battery and insert it into the battery compartment. Ensure the + side of the battery is facing down (opposite of how the old battery was oriented). Press down gently until the new battery clicks securely into place.
-
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 indicating that the fob is securely closed.
-
Replace the Emergency Key: Slide the emergency mechanical key back into its slot until it clicks and locks into position.
