If you own a 2018 Hyundai and your key fob is acting up, a dead battery might be the culprit. Thankfully, replacing a Hyundai key fob battery is a relatively simple DIY task that can save you a trip to the dealership. This guide provides a step-by-step walkthrough on how to replace your 2018 Hyundai key fob battery, along with helpful tips and answers to frequently asked questions.
Do I Need a New Hyundai Key Fob Battery?
Before you start prying open your key fob, it’s wise to confirm if a dead battery is actually the issue. Here are a few telltale signs that your Hyundai key fob battery needs replacement:
- Decreased Range: You find yourself having to stand closer to your car for the key fob to unlock or lock the doors.
- Intermittent Functioning: The key fob works sporadically, sometimes requiring multiple button presses.
- Warning Light on Dashboard: Some Hyundai models display a warning light on the dashboard indicating a low key fob battery.
If you experience any of these issues, it’s highly likely that your key fob battery needs a refresh.
What You’ll Need:
- A new CR2032 battery (easily found at most supermarkets, electronics stores, or online retailers)
- A small flat-head screwdriver or a similar prying tool
- Optional: A small container to keep the screws organized
How to Replace Your 2018 Hyundai Key Fob Battery:
- Locate the Release Button: Examine your Hyundai key fob and locate the small release button or switch, typically on the back.
- Release the Mechanical Key: Press the release button and gently slide out the mechanical key from the fob.
- Separate the Fob Halves: Using your flat-head screwdriver or prying tool, carefully insert it into the seam where the two halves of the key fob meet. Gently pry the halves apart.
- Remove and Replace the Battery: Once open, you’ll see the CR2032 battery nestled inside. Carefully remove it by prying it out with your screwdriver or fingernail. Avoid touching the battery’s flat surfaces to prevent draining its charge. Insert the new battery, ensuring the positive (+) side faces up, just like the old battery.
- Reassemble the Key Fob: Align the two halves of the key fob and press them firmly together until you hear a click, indicating they’re securely closed.
- Reinsert the Mechanical Key: Slide the mechanical key back into its slot on the fob.
- Test Your Key Fob: Test all the buttons (lock, unlock, panic, etc.) to ensure your new battery is working correctly.
