2015 Hyundai Sonata Limited Key Fob Battery Replacement: A Quick Guide

Is your 2015 Hyundai Sonata Limited key fob acting up? Before you panic and schedule a pricey trip to the dealership, there’s a good chance it’s just a dead battery. Don’t worry, replacing it is a task even the most mechanically challenged among us (myself included!) can handle. This guide will walk you through the process step-by-step, so you can get back on the road with a fully functional key fob in no time.

Do I Need a New Key Fob Battery?

Key fob batteries don’t last forever. Over time, they lose their charge and need to be replaced. Here are a few telltale signs that your 2015 Hyundai Sonata Limited key fob might need a new battery:

Decreased Range: You find yourself having to stand closer to your car to lock or unlock the doors.
Intermittent Functioning: The key fob works sometimes, but not others, or requires multiple button presses.
No Response: The car doesn’t respond at all to any button presses on the key fob.

If you’re experiencing any of these symptoms, it’s a strong indication that your key fob battery is on its last legs and needs replacing.

What You’ll Need

Before you begin, gather these simple tools:

A new CR2032 battery (commonly available at grocery stores, pharmacies, and auto parts stores).
A small flathead screwdriver.

Let’s Replace That Battery!

Follow these easy steps to replace the battery in your 2015 Hyundai Sonata Limited key fob:

Locate the Key Release: On the back of your key fob, you’ll see a small button. Press this button to release the metal key from the fob.
Find the Seam: With the metal key removed, examine the key fob casing. You’ll notice a seam running around the edge.
Gently Pry Open the Casing: Carefully insert the flathead screwdriver into the seam and gently pry the two halves of the key fob casing apart. Be careful not to use excessive force, as this could damage the casing.
Remove the Old Battery: Inside the key fob, you’ll find the CR2032 battery. Carefully remove it, noting which side is facing up (usually the positive “+” side).
Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring the positive “+” side matches the orientation of the old battery.
Reassemble the Key Fob: Align the two halves of the key fob casing and press them together firmly until you hear a click, indicating they are securely closed.
Test the Key Fob: Try locking and unlocking your car doors to make sure the new battery is working properly.

Still Having Trouble?

If you’ve replaced the battery and your key fob is still acting up, don’t fret just yet. There are a few other possibilities:

Programming Required: In some cases, you may need to reprogram your key fob after replacing the battery. Refer to your owner’s manual for specific instructions on how to do this for your 2015 Hyundai Sonata Limited.
Key Fob Malfunction: If reprogramming doesn’t resolve the issue, there might be a malfunction with the key fob itself. It’s best to consult a qualified automotive locksmith or your Hyundai dealership for further diagnosis and repair.
