What You’ll Need to Change Your Key Fob Battery
Before you begin, gather these simple items:
- A new CR2032 3V battery: This is the standard battery for most Nissan key fobs, including your 2017 Sentra. You can find these at most drugstores, supermarkets, and online retailers for a few dollars. Consider buying a multipack to have spares on hand.
- A small flathead screwdriver: This will be used to gently open the key fob casing.
- Latex or non-latex gloves (optional): Wearing gloves can help protect the sensitive electronic components inside the key fob from static and oils from your fingers.
Step-by-Step Guide to Replacing Your Nissan Sentra 2017 Key Fob Battery
Follow these easy steps to replace your dead key fob battery:
-
Turn the Key Fob Over: Flip your Nissan Sentra key fob to the back side, where you’ll find the emergency key release.
-
Release and Remove the Emergency Key: Locate the small slider or button designed to unlock the emergency key. Slide or press it to release the key, and then pull the emergency key straight out from the fob.
-
Locate the Notch: Look at the top of the key fob, where the key ring would attach. You’ll see a small notch or opening along the seam between the front and back halves of the fob.
-
Insert the Flathead Screwdriver: Carefully insert the tip of your small flathead screwdriver into this notch.
-
Gently Pry Open the Fob: Twist the screwdriver gently. This will start to separate the front and back halves of the key fob. You may hear a click as the casing begins to open. Avoid using excessive force to prevent damage to the plastic.
-
Separate the Fob Halves: Once you’ve created a gap with the screwdriver, you should be able to carefully pull the two halves of the key fob completely apart by hand.
-
Identify the Old Battery: In the back half of the key fob, you’ll see the old, dead CR2032 battery. It’s usually held in place by small clips.
-
Remove the Old Battery: Use the flathead screwdriver to gently pop the old battery out of its housing. Be careful not to damage the surrounding components.
-
Insert the New Battery: Take your new CR2032 battery and insert it into the battery compartment. Make sure the “+” (positive) side of the battery is facing down, towards the inside of the key fob half.
-
Click the New Battery into Place: Press down on the new battery until it clicks securely into position.
-
Reassemble the Fob Halves: Carefully line up the front and back halves of the key fob.
-
Snap the Fob Back Together: Squeeze the two halves firmly together until they click back into place completely, ensuring a secure closure.
-
Replace the Emergency Key: Slide the emergency key back into its slot until it clicks and locks into place.
-
Test Your Key Fob: Press the unlock or lock button on your key fob to test if the new battery is working. Your 2017 Nissan Sentra should respond immediately.
