Experiencing issues with your 2020 Hyundai key fob? A common culprit is often a low or dead battery. It can be frustrating when your key fob fails to unlock your car or start the engine, leaving you potentially stranded. This guide will walk you through understanding the signs of a dying key fob battery and how to easily replace it yourself.
Recognizing the Signs of a Low Key Fob Battery
Before your Hyundai key fob completely stops working, it usually gives warning signs. For 2020 Hyundai models, if you notice that you need to be closer to your car than usual to unlock the doors, or if the “key not detected” message appears on your dashboard even when the fob is inside the vehicle, these are strong indicators of a weakening battery. You might also find that the range of your remote start is significantly reduced. These subtle hints are your cue to consider a battery replacement before it becomes a bigger issue.
What You’ll Need: The CR2032 Battery
The good news is that replacing your Hyundai key fob battery for the 2020 models is a straightforward process and requires a common and inexpensive battery. Most Hyundai key fobs, including those for the 2020 range, utilize a CR2032 3V lithium battery. This type of battery is widely available at most drugstores, supermarkets, and online retailers. Keeping a spare CR2032 battery on hand can save you from inconvenience and potential delays.
Step-by-Step Hyundai Key Fob Battery Replacement
While specific steps can slightly vary depending on your exact 2020 Hyundai model (like Ioniq, Sonata, Elantra, etc.), the general process for replacing the key fob battery is quite similar across many models. Typically, you will need a small flathead screwdriver or a similar tool to gently pry open the key fob casing. Once opened, you’ll be able to access the battery compartment. Carefully remove the old CR2032 battery and replace it with a new one, ensuring the positive (+) side is facing upwards as indicated in the compartment. After replacing the battery, securely close the key fob casing until it clicks shut.
Proactive Tip: Always Carry a Spare Battery
To avoid being caught off guard by a dead key fob battery, especially when you’re far from home, it’s a smart idea to keep a spare CR2032 battery in your car. A glove compartment or your owner’s manual packet are perfect places to store a spare. This simple step can provide peace of mind and ensure you’re always prepared. Regularly checking your spare battery’s expiration date is also a good practice to ensure it’s ready when you need it.
Conclusion
Replacing the battery in your 2020 Hyundai key fob is an easy and cost-effective maintenance task you can do yourself. By recognizing the warning signs and keeping a spare CR2032 battery available, you can prevent key fob battery issues from disrupting your day. Taking this proactive approach ensures you maintain reliable access to your vehicle and avoid potential inconveniences.
