Is your 2010 Hyundai Genesis key fob starting to feel unresponsive? You might be experiencing the common frustration of a dying key fob battery. Don’t rush to the dealership for an expensive replacement. Changing the battery in your Hyundai Genesis key fob is a simple task you can easily accomplish yourself with just a few basic tools and a little patience. This guide will walk you through each step, saving you time and money.
What You’ll Need
Before you begin, gather these simple tools:
- A Flathead Screwdriver: A standard size screwdriver with about a ½” blade will work perfectly.
- CR2032 Battery: This is the specific type of battery your 2010 Hyundai Genesis key fob requires. You can find these widely available at drugstores, supermarkets, and online retailers.
Step-by-Step Guide to Battery Replacement
Let’s get started with replacing your key fob battery. Follow these easy steps:
Step 1: Remove the Mechanical Key
Begin by removing the physical key from the key fob. Locate the small silver button on your key fob, press it, and slide the mechanical key out. Set the key aside in a safe place.
Step 2: Open the Key Fob Casing
Now, take your flathead screwdriver and examine the key fob. You’ll notice a small, shallow slot located near where the mechanical key was just removed. Carefully insert the blade of your screwdriver into this slot.
With the screwdriver inserted, gently pivot or twist the screwdriver head. Apply slight pressure to separate the two halves of the key fob casing. You should hear a click or pop as the casing begins to open on that side. Don’t force it; gentle pressure is key.
Step 3: Access and Replace the Battery
Once one side is slightly open, insert the tip of your screwdriver into the opening and gently pivot again. This should cause the opposite side to start separating. At this point, you can usually use your hands to carefully pull the two halves of the key fob completely apart.
Important: Before fully separating the two halves, make sure the button side of the fob is facing downwards. This will prevent the small internal components from falling out and getting lost.
With the fob open, you’ll see the battery located in the half of the fob that typically has the Hyundai logo on the back. The battery is held in place by a small circular spring clip. Use your flathead screwdriver to gently pry the old CR2032 battery out from under this clip.
Take your new CR2032 battery and install it with the positive (+) side facing down into the battery compartment. To secure it, press one edge of the battery under the spring clip and then push the other side down until it clicks into place.
Step 4: Reassemble the Key Fob
Carefully align the two halves of the key fob casing back together. Press them firmly until they snap securely closed. Ensure there are no gaps between the two halves.
If the key release button assembly happened to come apart during disassembly (it’s a small metal button, spring, and white plastic piece), don’t worry. To reassemble it: Place the metal button into its hole on the button side of the fob. Then, position the small spring on the back of the metal button, using the small post to guide it. Finally, place the white plastic piece on top of the spring, aligning the cutout on the white piece with the spring and pointing the tail of the white piece towards the top of the fob. It should balance in place for reassembly.
Step 5: Test Your Key Fob
Once reassembled, test all the buttons on your 2010 Hyundai Genesis key fob to ensure they are working correctly. Your car should respond to the lock, unlock, and panic buttons as expected. If everything works, you’ve successfully replaced your key fob battery!
Conclusion
Replacing the battery in your 2010 Hyundai Genesis key fob is a straightforward DIY task that requires minimal tools and effort. By following these simple steps, you can avoid unnecessary dealership costs and keep your key fob working reliably.
