Changing a Hyundai key fob battery involves a few simple steps:
- First, you need to locate the small notch on the side of the key fob.
- Use a flathead screwdriver to gently pry open the key fob.
- Once the key fob is open, carefully remove the old CR2032 battery.
- Replace it with a new CR2032 battery, ensuring it is inserted with the correct polarity.
- Finally, snap the key fob back together until it securely clicks into place.
Gather Your Tools
To change your Hyundai key battery, gather these tools:
- a small flathead screwdriver or a prying tool for opening the key fob without damage. A plastic tool is better to avoid scratches.
- Check if your key fob needs a CR2032 battery by looking in the owner's manual or at the current battery.
- You can buy this battery at electronics stores, supermarkets, or online.
- Use a soft or microfiber cloth to handle the new battery to avoid oil transfer from your hands, which can shorten the battery's life. This cloth can also clean the battery area and contacts before installation.
With these tools, you're ready to change your Hyundai key battery. Be patient and careful to keep the key fob in good condition.
Locate the Key Fob Slot
To open a Hyundai key fob, look for a small slot or notch on its side or bottom. The slot's location varies with the model and year of your Hyundai. Here's where you might find the slot on different models:
- 2011-2015: Bottom Edge
- 2016-2018: Side Near Top
- 2019-2021: Bottom Edge
- 2022: Side Near Middle
- 2023: Side Near Bottom
If you can't find the slot, check the key fob carefully as its design may vary. Once you find the slot, you can open the battery compartment. The steps to open it will be discussed later.
Open the Key Fob
Find the key fob slot and use a flathead screwdriver to gently open it. Don't use too much force to avoid damaging the key fob. Carefully twist or lever the tool in the slot to open the fob. Continue with caution and don't apply pressure incorrectly. If it's hard to open, try again from a different angle. Be patient.
You might feel the fob resist as it opens. This means slow down and check your force. Some Hyundai key fobs have tighter seals or extra clips that need more effort to open. Gently use the tool around the fob's edge to separate the halves.
After opening the key fob, be careful not to rush. The inside parts are sensitive and can be damaged easily. Make sure everything inside isn't disturbed as you move to the next step.
Replace the Battery
Open the key fob and find the old battery. Note how it's placed, especially which side is up.
Remove the old battery. You might need a small screwdriver to pry it out. If there's a clip holding the battery, gently release it.
Get a new battery, usually a CR2032, but check your manual or old battery to be sure. Install it the same way the old one sat, usually with the positive side up.
Check that everything is in place and the battery sits flat. Close the key fob by pressing the halves together until they click.
Test the New Battery
After replacing the battery in your key fob, immediately check if it works correctly. This confirms your car will respond when needed.
First, stand close to your Hyundai and press the unlock button on the key fob. The car should unlock immediately. If not, try locking and unlocking again. Make sure there are no interference sources nearby and that you're within range.
Then, test other key fob functions like the lock button, trunk release, and panic button, if available. Each should work without delay.
If any button doesn't work, check the battery's placement to ensure it's not upside down and look for any debris or damage inside the key fob.
If everything works, you've successfully changed the battery. Keep a spare battery for the future. Regular testing, especially after a battery change, is important to avoid being locked out of your vehicle.
Conclusion
You've changed your Hyundai key battery!
First, get the tools you need. Then, find the slot on the fob, open it, and put in a new battery instead of the old one. Make sure to check if the new battery works right. These simple steps help you keep your Hyundai key fob working great.
Now, you can use your car's remote features easily.
