A dead key fob battery can be a real pain, leaving you stranded and unable to unlock your Nissan. But don’t worry, changing the battery in your Nissan key fob is a quick and easy process that anyone can do. This guide will walk you through each step, ensuring you’re back in the driver’s seat in no time.
What You’ll Need to Change Your Nissan Key Fob Battery
Before you begin, gather the following items:
- Your Nissan key fob
- A small flat-head screwdriver
- A new CR2032 battery (this is the most common type for Nissan key fobs, but check your owner’s manual to confirm)
Steps to Replace Your Nissan Key Fob Battery
Once you have everything you need, follow these simple steps:
-
Locate the release button. On the back of your Nissan key fob, you’ll find a small release button. It might be marked with a key symbol or a lock icon.
-
Release the key. Press the release button and gently pull out the metal key from the fob.
-
Open the key fob. Using the flat-head screwdriver, carefully pry open the key fob casing. There’s usually a small notch where you can insert the screwdriver. Be gentle to avoid damaging the casing.
-
Remove the old battery. Once the casing is open, you’ll see the old CR2032 battery. Gently pry it out using the screwdriver or your fingernail. Avoid touching the battery’s flat surfaces to prevent discharge.
-
Insert the new battery. Place the new CR2032 battery into the slot, ensuring the positive (+) side is facing up. You can usually find a “+” marking inside the battery compartment.
-
Reassemble the key fob. Carefully align the two halves of the key fob casing and press them together until you hear a click, indicating the fob is securely closed.
-
Test the key fob. Put the metal key back into its slot and test all the buttons on your key fob (lock, unlock, panic) to ensure the new battery is working correctly.
Still Having Trouble?
If you’ve replaced the battery and your Nissan key fob still isn’t working, there might be other issues at play. Here are a few things to consider:
- Check the battery installation: Double-check that you installed the new battery correctly, with the positive (+) side facing up.
- Clean the battery contacts: Over time, the battery contacts inside the key fob can become corroded. Use a cotton swab and a small amount of rubbing alcohol to clean the contacts gently.
- Try reprogramming the key fob: In some cases, you might need to reprogram the key fob after replacing the battery. Refer to your Nissan owner’s manual for instructions on how to do this.
- Contact a Nissan dealership or qualified automotive locksmith: If you’ve tried all the above steps and your key fob still isn’t working, it’s best to seek professional help. They can diagnose the problem and provide a solution.
