This guide will walk you through everything you need to know about your Hyundai Tucson Key Fob Battery, from identifying the signs of a low battery to replacing it yourself and even programming a new one.

Recognizing a Weak Key Fob Battery

Before you go through the trouble of replacing your battery, it’s important to make sure that’s actually the problem. Here are some telltale signs that your Hyundai Tucson key fob battery is losing its juice:

Decreased Range: You find yourself standing closer and closer to your car before the key fob works.
Intermittent Functionality: The key fob works sometimes, but not others, or requires multiple button presses.
Warning Light on Dashboard: Some Hyundai Tucsons will display a warning light on the dashboard, indicating a low key fob battery.

If you’re experiencing any of these issues, there’s a good chance your key fob battery needs replacing. The good news? It’s a quick and easy fix you can often do yourself!

How to Replace Your Hyundai Tucson Key Fob Battery

Replacing your Hyundai Tucson key fob battery is a straightforward process. Here’s a step-by-step guide:

Identify Your Key Fob Type: Hyundai Tucson key fobs come in various shapes and sizes. Locate the small groove or notch on the side and use a flathead screwdriver or a coin to pry open the key fob casing.
Locate the Battery: Inside, you’ll find a small, round, flat battery. This is your key fob battery.
Note Battery Type: Take note of the battery type printed on the side (usually CR2032 or CR2025).
Remove and Replace: Carefully remove the old battery and insert the new one, ensuring the positive (+) side faces up.
Reassemble the Key Fob: Align the two halves of the key fob casing and press them firmly together until you hear a click.

And that’s it! You’ve successfully replaced your Hyundai Tucson key fob battery.

Do I Need to Reprogram My Key Fob After Battery Replacement?

In most cases, no. Replacing the battery in your Hyundai Tucson key fob doesn’t typically require reprogramming. The key fob should automatically synchronize with your car once you replace the battery and put the key fob back together.

When You Might Need to Reprogram Your Key Fob

While a simple battery swap usually doesn’t require reprogramming, certain situations might necessitate it. These include:

Replacing the Entire Key Fob: If you’ve purchased a brand new key fob, you’ll need to program it to your specific Hyundai Tucson.
Key Fob Malfunction: If your key fob was malfunctioning before the battery replacement, reprogramming might be necessary.

For information on programming your 2014 Hyundai Tucson OBD key fob programmer, refer to your owner’s manual or consult a professional locksmith or dealership.

Tips for Maintaining Your Hyundai Tucson Key Fob

Want to extend the life of your key fob battery and keep it functioning smoothly? Here are some helpful tips:

Avoid Extreme Temperatures: Just like your car battery, your key fob battery doesn’t appreciate extreme heat or cold.
Store Your Key Fob Properly: Keep your key fob in a cool, dry place when not in use.
Don’t Panic if Your Key Fob Gets Wet: While it’s best to avoid getting it soaked, most modern key fobs are water-resistant to a degree. If it gets wet, remove the battery and allow everything to dry thoroughly before reassembling.
