Nissan Sentra 2012 Key Fob Battery – Tips and Tricks


The Nissan Sentra 2012 is a popular car model known for its reliability and performance. One of the key features of this vehicle is the key fob, which allows for convenient access and control of the car. However, over time, the battery in the key fob may need to be replaced. In this article, we will guide you through the process of changing the key fob battery in your Nissan Sentra 2012.

Identifying the Key Fob

Before we start, it’s important to identify the type of key fob you have. The Nissan Sentra 2012 key fob comes in two variations: the basic key fob and the key fob with a built-in key. The process of changing the battery is slightly different for each type.

Basic Key Fob

If you have the basic key fob without a built-in key, follow these steps to replace the battery:

Step 1: Gather the Necessary Tools

To replace the battery, you will need a small flathead screwdriver and a replacement CR2032 battery. These items are readily available at most hardware stores or online retailers.

Step 2: Open the Key Fob

Using the small flathead screwdriver, carefully pry open the key fob. Start at the small opening near the keyring and gently work your way around the edges to release the clips holding the key fob together. Be careful not to apply too much force to avoid damaging the key fob.

Step 3: Remove the Old Battery

Once the key fob is open, you will see the battery compartment. Use the screwdriver or your fingernail to gently lift the old battery out of the compartment. Dispose of the old battery properly.

Step 4: Insert the New Battery

Take the new CR2032 battery and place it into the battery compartment with the positive (+) side facing up. Ensure that the battery is securely in place.

Step 5: Close the Key Fob

Carefully align the two halves of the key fob and press them together until you hear a click, indicating that the clips are securely fastened. Ensure that the keyring is properly attached.


By following these simple steps, you can easily replace the key fob battery in your Nissan Sentra 2012. Regularly checking and replacing the battery will ensure that your key fob continues to function properly, providing you with convenient access to your vehicle. If you have any difficulties or further questions, it is recommended to consult your vehicle’s owner manual or contact a professional for assistance.
