Luckily, changing the key fob battery in your 2018 Hyundai Sonata is a quick and easy process you can do yourself. In this guide, we’ll walk you through everything you need to know about the 2018 Hyundai Sonata key fob battery, from identifying the signs of a low battery to replacing it yourself.
Signs Your 2018 Hyundai Sonata Key Fob Battery Needs Replacing
Key fobs are powered by small but mighty batteries that eventually run out of juice. Here are some telltale signs that your 2018 Hyundai Sonata key fob battery needs replacing:
- Decreased Range: Are you noticing that you need to be much closer to your car for the key fob to work? A dying battery often results in a significantly reduced signal range.
- Inconsistent Locking/Unlocking: Does your car sometimes lock and unlock with the key fob and sometimes not? This inconsistent behavior can indicate a weak battery.
- Dashboard Warning: Some Hyundai Sonatas may display a “Key Fob Battery Low” message on the dashboard, giving you a direct heads-up.
- Slow Response: If your key fob seems to be lagging or responding slowly to your button presses, the battery is likely the issue.
What Kind of Battery Does a 2018 Hyundai Sonata Key Fob Take?
The 2018 Hyundai Sonata key fob uses a CR2032 battery, a common type of lithium coin battery. You can find these batteries at most drugstores, supermarkets, and electronics retailers.
How to Change the Battery in Your 2018 Hyundai Sonata Key Fob: A Step-by-Step Guide
Replacing your 2018 Hyundai Sonata key fob battery is a breeze. Here’s a simple, step-by-step guide:
- Locate the Key Fob’s Release Button: On the back of your key fob, find the small release button or switch.
- Release the Mechanical Key: Press the release button and gently slide out the mechanical key from the fob.
- Separate the Fob Halves: Use the tip of the mechanical key or a small flat-head screwdriver to carefully pry open the key fob casing. Start at the notch where the key was released, and work your way around.
- Identify and Remove the Old Battery: Once open, you’ll see the CR2032 battery. Carefully remove it by prying it out with your fingernail or a small, non-metallic tool.
- Install the New Battery: Insert the new CR2032 battery, making sure the positive (+) side faces upwards, 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 them snap back into place.
- Test the Key Fob: Try locking and unlocking your car with the key fob to ensure the new battery is working correctly.
Tips for Changing Your Key Fob Battery
- Handle the battery with care: Avoid touching the flat surfaces of the new battery, as this can reduce its lifespan. Hold it by the edges.
- Don’t force it: Be gentle when opening and closing the key fob to avoid damaging the casing or internal components.
