2018 Hyundai Key Fob Battery Replacement: A Quick Guide

Is your 2018 Hyundai key fob acting up? Before you head to the dealership, a dead battery might be the culprit. Don’t worry, replacing it is usually a quick and easy fix you can handle at home. This guide will walk you through everything you need to know about 2018 Hyundai Key Fob Battery Replacement, from identifying the signs of a dying battery to getting your key fob back in action.

How Do I Know My Hyundai Key Fob Battery Needs Replacing?

Your Hyundai key fob relies on a battery to send signals to your car. When the battery starts to die, those signals weaken, leading to some telltale signs:

• Decreased Range: You need to be much closer to your car for the key fob to work.
• Intermittent Functionality: The key fob works sometimes but not others, or you have to press the buttons multiple times.
• Dashboard Warning Light: Some Hyundai models display a warning light on the dashboard when the key fob battery is low.

If you’re experiencing any of these issues, it’s a good bet that your key fob battery needs replacing.

What Kind of Battery Does My 2018 Hyundai Key Fob Use?

Most 2018 Hyundai key fobs use a CR2032 battery, a common type of lithium coin battery. You can find them at most electronics stores, supermarkets, and online retailers.

What You’ll Need for the Replacement

Before you begin, gather these simple tools:
