Identifying the Right Battery for Your 2009 Nissan Altima Key Fob
Before you begin, it’s crucial to know the correct 2009 Nissan Altima Key Fob Battery Size. For the 2009 Nissan Altima, and many other Nissan models of this era, the key fob uses a CR2032 3V battery. This is a widely available and inexpensive coin cell battery that you can find at most drugstores, supermarkets, and online retailers. To be absolutely sure, you can always double-check the old battery once you open the key fob, but CR2032 is indeed the standard 2009 nissan altima key fob battery size.
Step-by-Step Guide to Replacing Your 2009 Nissan Altima Key Fob Battery
Here’s how to replace the battery in your 2009 Nissan Altima key fob:
-
Prepare Your Workspace and Tools: Find a clean, well-lit area to work. Gather a new CR2032 3V battery and a small flathead screwdriver. Wearing gloves (like latex or nitrile) is recommended to protect the key fob’s internal components from static and oils from your skin.
-
Access the Emergency Key: Flip your Nissan key fob 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 the emergency key. Then, gently pull the key out of the fob.
-
Open the Key Fob Casing: With the emergency key removed, look at the top of the key fob where the key was just located. You should see a small notch or slot where the two halves of the fob casing meet.
-
Separate the Fob Halves: Insert the tip of your flathead screwdriver into this notch. Gently twist the screwdriver. This will apply leverage to separate the front and back halves of the key fob casing. Be patient and avoid using excessive force to prevent damage to the plastic.
-
Locate and Remove the Old Battery: Once the fob is open, the battery compartment will be visible in one of the halves. You’ll see the old CR2032 battery. Use the flathead screwdriver to carefully pry the old battery out of its holder. Note the orientation of the battery – usually, the positive (+) side faces up or is indicated by markings in the battery compartment.
-
Insert the New Battery: Take your new CR2032 battery and insert it into the battery compartment. Ensure the + side is facing down as you place it in, matching the original orientation of the old battery. 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 casing. Press them firmly together until they snap or click back into place, ensuring a secure closure.
-
Replace the Emergency Key: Slide the emergency mechanical key back into its slot in the key fob until it clicks and locks securely.
-
Test Your Key Fob: Press the buttons on your key fob to test if it is now working. Your 2009 Nissan Altima should respond to the lock, unlock, and panic buttons. Remote start functionality (if equipped) should also be restored.
