How To Change the Battery in Hyundai Key Fob

Every once in a while, you’ll need to change the battery in your Hyundai key fob when it runs low or stops responding on your Reno commute. To do this, you’ll need to learn how to open, change, and program the Hyundai key fob. Luckily, this process is relatively easy and can be performed at your Sparks home! Learn how to change your Hyundai key fob battery below.

How to Open Hyundai Key Fob

The first thing you’ll need to know to replace the battery in your key fob is the steps on how to open the Hyundai key fob. You should know that this process will be different depending on if you drive a new Hyundai model or an older one, but not drastically. Read below to see the steps:

1. If you drive a newer Hyundai model, you will open your key fob differently. Begin by removing the metal key by pressing and holding the metal tab or button. Next, use the metal key to open the back cover on your key fob by inserting it into the small opening and turning it in either direction. The case should pop right open.
2. If you drive an older Hyundai model, you will begin by finding a small notch or indent along the side of your key fob. Then, use a coin or a flat blade screwdriver to gently pop open the key fob from the notch by turning it in either direction.
3. Now that you have your key fob open, carefully lift the circuit board to expose the battery. Take a photo or a note of how the battery is laying in the key fob before removing it. This will make placing the new battery easier.
4. See what kind of battery your key fob has and buy a replacement. Most Hyundai key fobs run on a CR2032 battery. These are cheap batteries that are easy to find in Fernley or online.
5. With your Hyundai key fob battery replacement, place it into your key fob using your photo as a reference. Ensure that the battery is making contact with all the appropriate connections.
6. If you removed a metal key earlier, make sure to replace it when your keyfob is back together.

After you’ve successfully replaced the battery in your keyfob, you’ll need to reprogram it to your vehicle. Don’t worry, this process is as easy as replacing your battery! Read below to learn how to program a Hyundai key fob at your Carson City home.

How to Program a Hyundai Key Fob

Now that you’ve replaced the key fob in your battery, you’ll need to reprogram the key fob to your vehicle. The steps for reprogramming a Hyundai key fob are relatively easy. We’ve listed them for you below:

1. Get inside of your Hyundai and ensure all the doors are closed.
2. Use your key to turn your Hyundai to the “ACC” (accessory) position on your ignition.
3. Hold the “open” or “unlock” button on the key fob until your vehicle’s light flashes.
4. Congratulations! Your key fob is now programmed to your vehicle.
5. As a precaution, you should test to see if it’s working properly. If it’s not, re-open the case to ensure the battery is sitting right and the connections are touching and in good condition before reprogramming it to your Hyundai again. If the key fob still doesn’t work, you may need to get a Hyundai key fob replacement.

It’s important to note that this programming method will only work on key fobs that have been previously programmed to your Hyundai. If you have a brand new key fob, you will need to stop by a Hyundai service center to have it programmed to your car.

Unlock Your Car with the Hyundai Digital Key

If you’re in a pinch on your Reno commute and don’t have time to replace your key fob battery or reprogram your keyfob, you can use the Hyundai Digital Key to access your vehicle from your smartphone. With the Hyundai Digital Key, you can unlock your vehicle by holding your smartphone against the driver or passenger door handle. Once you’re inside your vehicle, just place your phone on the wireless charger, push the start button, and go!

The Hyundai Digital Key first became available on the 2020 Hyundai Sonata and has since migrated to many new Hyundai models. The app is a free download for Android phones from the Google Play Store but is not available for iPhones. Once you’ve downloaded the Hyundai Digital Key app, it will walk you through a quick setup and then help you unlock your vehicle.

If you cannot access the Hyundai Digital Key app, some new Hyundai models will come with a Hyundai Smart Key when you purchase them. The Hyundai Smart Key will give you passive entry and keyless start abilities for your vehicle, so you can get back on the road and on with your day!
