Step-by-Step 2010 Hyundai Genesis Key Fob Battery Replacement Guide
Follow these easy steps to replace your 2010 Hyundai Genesis key fob battery:
Step 1: Remove the Mechanical Key
Start by removing the mechanical key from the key fob. Locate the small silver button on your fob – usually near the key ring. Press and hold this button to release the mechanical key. Slide the key out and set it aside.
Step 2: Locate the Opening Slot
Examine the key fob closely where the mechanical key was just removed. You’ll see a shallow slot or notch next to the key slot. This is where you’ll insert your flathead screwdriver to begin opening the fob.
Step 3: Pry Open the Key Fob
Carefully insert the blade of your flathead screwdriver into the slot. Gently pivot or twist the screwdriver head within the hole. Apply slight pressure to separate the two halves of the key fob. You should hear or feel a pop as one side of the fob begins to loosen.
Step 4: Fully Separate the Fob Casing
Insert the screwdriver tip into the partially opened side of the fob. Again, gently pivot the screwdriver head to further separate the casing. The fob should pop open a second time, and the opposite side will start to come apart.
Important Tip: Before fully separating the two halves, turn the fob button-side down. This prevents the internal components, especially the small key release button parts, from falling out and getting lost.
Step 5: Access and Remove the Old Battery
Carefully separate the two halves of the key fob completely by hand. The battery is located in the half of the fob that typically has the Hyundai logo on the back. You’ll see the CR2032 battery held in place by a small circular spring clip. Use your flathead screwdriver to gently pry the old battery out from under the spring clip.
Step 6: Install the New CR2032 Battery
Take your new CR2032 battery. Ensure the + (positive) side of the battery is facing down into the battery tray. To install it, slide one edge of the battery under the spring clip and then press down on the other side until it snaps into place. Avoid forcing it; it should seat easily.
Step 7: Reassemble the Key Fob
Carefully align the two halves of the key fob, ensuring the key release button assembly (if it came apart) is correctly positioned. Press the two halves firmly together until they snap securely back into place.
Step 8: Test Your Key Fob
Test all the buttons on your key fob to ensure they are working correctly. Try locking and unlocking your 2010 Hyundai Genesis remotely. If everything functions as expected, you’ve successfully completed your 2010 Hyundai Genesis Key Fob Battery Replacement!
Reassembling the Key Release Button (If Necessary)
If the key release button parts came loose during disassembly (specifically the metal button, small spring, and white plastic piece), here’s how to put them back together:
- Place the metal button into the designated hole on the button side of the fob.
- Position the small spring onto the small post on the back of the metal button.
- Place the white plastic piece on top of the spring, aligning the cutout or hole on the white piece with the spring. The tail of the white plastic piece should point towards the top of the fob.
These pieces will sit loosely together, so you’ll need to carefully balance them while reassembling the fob halves.
Conclusion
Replacing the battery in your 2010 Hyundai Genesis key fob is a quick and easy DIY task. By following these simple steps, you can avoid dealership costs and get your key fob working like new again. With just a screwdriver and a CR2032 battery, you’re back in control.
