Is your 2012 Hyundai Genesis key fob starting to act up? Don’t get stranded or spend unnecessary money at the dealership. A weak or dead key fob battery is a common issue, but thankfully, it’s a super easy fix you can handle yourself with just a simple tool and a few minutes of your time. This guide will walk you through replacing your 2012 Hyundai Genesis Key Fob Battery, saving you both time and money.
What You’ll Need
Before you begin, gather these simple tools and supplies:
- Flathead screwdriver: A small to medium-sized flathead screwdriver (around ½” blade) will work perfectly.
- CR2032 Battery: You’ll need a fresh CR2032 battery. This is a common type of coin cell battery readily available at most drugstores, supermarkets, and online retailers.
Step-by-Step Guide to Replacing Your Key Fob Battery
Let’s get started with the battery replacement process. Follow these simple steps:
Step 1: Remove the Mechanical Key
Locate the small silver button on your key fob. Press and hold this button to release the mechanical key. Slide the key out and set it aside.
Step 2: Carefully Open the Key Fob
Now, examine the key fob. You’ll see a small slot located near where you removed the mechanical key. This is where you’ll insert your flathead screwdriver.
Insert the blade of your flathead screwdriver into this slot. Gently twist or pivot the screwdriver head. Apply slight pressure to separate the two halves of the key fob. You should hear a click or pop as the fob begins to open on that side.
Step 3: Access and Replace the Battery
Once you have created a gap, carefully work your screwdriver around the seam of the fob to separate the two halves completely. Important: Keep the button side of the fob facing downwards as you open it. This will help prevent the small internal components from falling out.
With the fob open, you’ll see the CR2032 battery. It’s typically located in the half of the fob with the Hyundai logo. The battery is held in place by a small metal clip. Use your flathead screwdriver to gently pry the old battery out from under the clip.
Take your new CR2032 battery. Ensure the positive (+) side of the battery is facing down as you install it into the battery tray. Slide one edge of the battery under the retaining clip and press down until it clicks into place.
Step 4: Reassemble the Key Fob
Before putting the two halves of the key fob back together, take a moment to check if any small parts have become dislodged, particularly the key release button components. If they have, refer to the image below for correct reassembly. The metal button goes first, followed by the spring and then the white plastic piece.
Carefully align the two halves of the key fob and press them firmly together until they snap closed. Ensure there are no gaps and that the fob feels securely reassembled.
Step 5: Test Your Key Fob
Finally, test all the buttons on your key fob to ensure they are working correctly. Try locking and unlocking your car remotely and starting your vehicle. If everything works as expected, you’ve successfully replaced your 2012 Hyundai Genesis key fob battery!
Conclusion
Replacing your 2012 Hyundai Genesis key fob battery is a simple task that anyone can accomplish with minimal tools and effort. By following these steps, you can avoid costly dealership service charges and keep your key fob working reliably. Enjoy the peace of mind knowing you’ve saved money and taken care of this minor car maintenance task yourself!
