2015 Hyundai Sonata Key Fob Battery Replacement: A Quick Guide

Is your 2015 Hyundai Sonata key fob acting up? Before you shell out big bucks at the dealership, a dead battery might be the culprit. Luckily, replacing it is a simple DIY job that anyone can do with just a few tools. This guide will walk you through the process step-by-step and get you back on the road in no time.

Signs You Need a New Key Fob Battery

Key fob batteries don’t last forever. Here are a few telltale signs that yours might need replacing:

Decreased Range: Do you find yourself standing closer and closer to your Sonata to lock or unlock the doors? This reduced range indicates your key fob battery is losing power.
Intermittent Functionality: Is your key fob working inconsistently? One minute it’s fine, the next it’s unresponsive. This erratic behavior is another sign of a dying battery.
Dashboard Warning: Some Hyundai Sonatas might display a “Key Fob Battery Low” warning on the dashboard, giving you a clear heads-up.

What You’ll Need

Replacing your 2015 Hyundai Sonata key fob battery requires only a couple of common household items:

A new CR2032 battery: This is the standard battery for most Hyundai key fobs.
A small flat-head screwdriver: This will help you pry open the key fob.
