2017 Hyundai Sonata Sport Key Fob Battery Replacement: A Quick Guide

If you’re driving a 2017 Hyundai Sonata Sport, chances are you rely heavily on your key fob for seamless entry and ignition. But what happens when your key fob starts acting up due to a low battery? Don’t fret! Replacing the battery in your 2017 Hyundai Sonata Sport key fob is a simple task that you can easily handle yourself.

How to Tell Your Key Fob Battery Needs Replacing

Before we delve into the replacement process, let’s first identify the telltale signs of a dying key fob battery. Look out for these common indicators:

Decreased Range: Is your key fob only working when you’re standing right next to your car? This reduced range is a primary indicator of a fading battery.
Inconsistent Locking/Unlocking: If you find yourself repeatedly pressing the lock or unlock buttons with little to no response, it’s time to consider a battery swap.
Dashboard Warning: Some Hyundai Sonata Sport models may display a dashboard warning message specifically indicating a low key fob battery.

What You’ll Need for the Replacement

Here’s a list of things you’ll need to gather before you begin:

New CR2032 Battery: This is the standard battery for most key fobs, including the 2017 Hyundai Sonata Sport.
Small Flat-Head Screwdriver: You’ll need this to pry open the key fob casing.

Follow these straightforward steps to replace your key fob battery:

Locate the Key Fob Release Button: On the back of your key fob, find the small button. Press this button to release the physical key from the fob.
Pry Open the Fob: Using the flat-head screwdriver, carefully insert it into the groove created when you removed the physical key. Gently pry open the fob casing. Be careful not to damage the internal components.

Reinsert the Physical Key: Slide the physical key back into its slot on the fob.
