2018 Hyundai Santa Fe Sport Key Fob Battery: What You Need to Know

Is your 2018 Hyundai Santa Fe Sport key fob acting up? Before you run to the dealership, it might just be a dead battery. We’ll walk you through everything you need to know about your key fob battery, from identifying the signs of a dying battery to replacing it yourself and even some handy tips to extend its lifespan.

How to Tell if Your Key Fob Battery is Dying

Key fob batteries don’t last forever. Over time, they lose their charge and need to be replaced. Here are a few telltale signs that your 2018 Hyundai Santa Fe Sport Key Fob Battery might be on its last legs:

Decreased Range: Are you noticing that you need to be closer to your car for the key fob to work? This reduced range is a classic sign of a weakening battery.
Intermittent Functioning: Is your car only unlocking sporadically, even when you’re sure you’re pressing the right button? This inconsistent behavior can be another sign of a dying battery.
Warning Light on Dashboard: Some Hyundai models will display a warning light on the dashboard when the key fob battery is low. Keep an eye out for this helpful indicator.

Replacing the Battery: A DIY Guide

Replacing your 2018 Hyundai Santa Fe Sport key fob battery is a surprisingly simple task. You don’t need to be a car expert to do it! Here’s a step-by-step guide:

Gather Your Supplies: You’ll need a new CR2032 battery (easily found at most stores), a small flathead screwdriver, and your key fob.
Locate the Release Button: On the back of your key fob, find the small release button. Press it to detach the physical key from the fob.
Open the Fob: Use the flathead screwdriver to carefully pry open the key fob casing. There’s usually a small notch or groove where you can insert the screwdriver.
Replace the Battery: Inside the fob, you’ll see the CR2032 battery. Gently remove it and replace it with the new one, making sure to match the “+” and “-” sides.
Reassemble the Fob: Carefully snap the two halves of the key fob back together.
Test It Out: Try locking and unlocking your car with the key fob to make sure the new battery is working.

Pro Tip: Avoid touching the top and bottom of the new battery with your fingers. This can transfer oils that may shorten its lifespan.

Can I Program a Hyundai Key Fob Myself?

Extending the Life of Your Key Fob Battery

Want to get the most out of your key fob battery? Here are a few helpful tips:

Keep It Dry: Moisture is another enemy of batteries. Avoid getting your key fob wet and store it in a dry place.
Don’t Panic-Press: We’ve all been there—frantically pressing the unlock button when we can’t find our car. But constantly pressing the buttons can drain the battery faster.
