Open Your Key Fob

The very first thing that you will need to know as it pertains to replacing the battery in your key fob is how to actually open the Hyundai key fob. You should also be made aware of the fact that this process can be different depending on if you drive an older or new Hyundai. However, it’s not a major difference. 

Change Your Hyundai Key Fob Battery

1. If you happen to drive a newer Hyundai model, then the way that you open your key fob will be a bit different. You can get started by taking out the metal key. To do this, you will have to press and hold the metal button at the same time. After that, you can open the back cover by using the meal key. Put it into the opening and turn it in either direction. The case will then open.
2. In case you own an older Hyundai model, you will have to find the small notch with your key fob. Once you do that, get a coin or a flat blade screwdriver, which you can use to open the key fob from the notch. You can open it by twisting or turning in any direction.
3. Now that you have the key fob open – even if you have a newer or older Hyundai – you will still have to carefully lift the circuit board so that you can see the battery. It is better if you take a photo of the exact position that the battery is in, which will make it easier for you to replace it. 
4. Determine the kind of battery that is required for your key fob so that you can get the right replacement battery. You should also know that the majority of Hyundai key fobs use the CR2032 battery. 
5. With your Hyundai key fob battery replacement, put it into your key fob or even use your photo for reference. You should make sure that the battery is actually making contact with the right connections.
6. If you removed a metal key earlier, make sure to replace it when your key fob is back together.

After you’ve managed to replace the battery in your key fob, it will have to be reprogrammed to your vehicle. However, this process is not complicated at all. Keep on reading to learn exactly how you can program a Hyundai key fob.
