Is your 2019 Hyundai Tucson key fob not working reliably? The most common culprit is often a dead or dying battery. Replacing the battery in your key fob is a simple task you can handle yourself, saving time and money. This guide will walk you through everything you need to know about your Hyundai Tucson 2019 Key Fob Battery.
Identifying the Right Battery for Your Hyundai Tucson Key Fob
The 2019 Hyundai Tucson smart key uses a CR2032 battery. This is a widely available and inexpensive 3V lithium coin cell battery. You can find CR2032 batteries at most drugstores, grocery stores, and electronics retailers. It’s always a good idea to keep a spare CR2032 battery at home so you’re prepared when your key fob battery eventually needs replacing.
Step-by-Step Guide to Replacing Your Key Fob Battery
Changing the battery in your 2019 Hyundai Tucson key fob is straightforward. Here’s how to do it:
-
Locate the Emergency Key: First, find the emergency insert key that slides into the bottom of your key fob. You’ll usually find a small release button or lever on the fob. Press or slide this to detach and remove the emergency key.
-
Open the Key Fob Casing: Once the emergency key is removed, you’ll see a slot or notch where the key was. Insert the emergency key (or a small flathead screwdriver if you’re careful) into this slot. Gently twist or pry to split the key fob casing open. The casing is usually made of two halves that snap together.
-
Remove the Old Battery: Carefully open the key fob. You’ll see the CR2032 battery inside. Note the orientation of the battery (usually positive side up). Gently pry out the old battery. You can use your fingernail or a small non-metallic tool to avoid damaging the battery compartment.
-
Insert the New Battery: Take your new CR2032 battery and insert it into the battery compartment. Make sure the positive (+) side is facing the correct way (usually upwards, matching the orientation of the old battery).
-
Reassemble the Key Fob: Carefully snap the two halves of the key fob casing back together until they are securely closed. Make sure there are no gaps.
-
Test Your Key Fob: Press the buttons on your key fob to test if it’s working. The lock, unlock, trunk release, and panic buttons should now function correctly.
Troubleshooting Key Fob Battery Issues
If you’ve replaced the battery and your key fob is still not working, here are a few things to check:
- Battery Orientation: Double-check that you inserted the new battery with the correct polarity (+ side up).
- Battery Freshness: Ensure the new battery is fresh and not expired. Sometimes batteries can lose charge while sitting on the shelf.
- Key Fob Damage: Inspect the key fob for any signs of damage, such as cracks or water damage, which could affect its functionality.
- Vehicle Issues: In rare cases, the problem might not be the key fob battery but an issue with your Hyundai Tucson’s receiver or electrical system.
If you continue to experience problems after replacing the battery and troubleshooting, it might be time to consider a replacement key fob or seek professional help from a locksmith or Hyundai dealership.
