2018 Hyundai Key Fob Battery: What You Need to Know

Owning a 2018 Hyundai means enjoying modern conveniences, and the key fob is no exception. But what happens when your key fob starts acting up? A dead battery is often the culprit. This guide will walk you through everything you need to know about your 2018 Hyundai Key Fob Battery, from identifying signs of a dying battery to replacing it yourself.

Signs Your Hyundai Key Fob Battery Needs Replacing

Before you start digging for tools, let’s look at some common signs that your key fob battery is nearing its end:

Decreased Range: Is your car only responding to the key fob at very close range? This is often the first sign of a weakening battery.
Intermittent Functioning: Does your car sometimes unlock with the key fob and sometimes not, even when you’re within range? A dying battery can lead to inconsistent signals.
Dashboard Warning: Some Hyundai models will display a “Key Fob Battery Low” warning on the dashboard, giving you a clear heads-up.
Physical Buttons: Do you find yourself pressing the buttons on your key fob harder than usual to get a response? This could be another indicator that the battery is fading.

Replacing Your 2018 Hyundai Key Fob Battery: A Step-by-Step Guide

Replacing the battery in your 2018 Hyundai key fob is a surprisingly simple task. You can save yourself a trip to the dealership by following these easy steps:

Gather Your Supplies: You’ll need a new CR2032 battery (readily available online or at most stores), a small flathead screwdriver, and your owner’s manual (in case you need model-specific instructions).
Locate the Battery Compartment: Most Hyundai key fobs have a small release button or notch on the back. Gently press this to separate the key fob casing.
Identify and Remove the Old Battery: The CR2032 battery is usually secured in a small compartment. Carefully pry it out using your flathead screwdriver, noting the orientation (positive side up).
Install the New Battery: Insert the new CR2032 battery, ensuring the positive (+) side is facing up, just as the old battery was positioned.
Reassemble the Key Fob: Align the two halves of the key fob casing and press them together firmly until you hear a click, indicating it’s securely closed.
Test Your Key Fob: Try locking and unlocking your car, as well as using other key fob functions, to ensure the new battery is working correctly.
