Replacing the battery in your Hyundai key fob is a simple task that can be completed in a few minutes. Whether your key fob is no longer working or the range has diminished, a new battery is likely the solution. Here’s a step-by-step guide on how to change the battery in your Hyundai key fob.
To begin, locate the small button or lever on the side of the key fob. Pressing or sliding this mechanism will release the key blade, allowing you to pull the two halves of the fob apart. Once the fob is open, you will see the battery inside. Carefully remove the old battery and replace it with a new one of the same type. Make sure the positive and negative terminals of the battery are facing the correct direction. Once the new battery is in place, snap the two halves of the fob back together. The key fob should now be working properly.
Replacing the battery in your Hyundai key fob is an easy and inexpensive way to keep your vehicle running smoothly. If you are experiencing any problems with your key fob, such as reduced range or intermittent operation, a new battery may be the solution. By following the steps outlined above, you can quickly and easily replace the battery in your Hyundai key fob and get back on the road.
Testing the Key Fob Function
Before you jump into replacing the key fob battery, it’s essential to confirm that the issue lies with a weak battery. Here are some simple steps to test the key fob’s function:
1. Proximity Function
If your Hyundai key fob features proximity entry, stand near your vehicle and try to unlock it by pulling the door handle. If the doors unlock smoothly, it indicates that the proximity function is working correctly.
2. Manual Unlock
Press the unlock button on the key fob. If the doors unlock smoothly, this confirms that the key fob is sending a signal to the vehicle, but it may still be a weak battery issue.
3. Trunk Release
Press the trunk release button on the key fob. If the trunk opens smoothly, it indicates that the key fob is functioning correctly, and there might not be a battery issue.
4. Panic Button
Most Hyundai key fobs come with a panic button. Press and hold the panic button for a few seconds. If the vehicle’s horn sounds or the lights flash, it indicates that the key fob is transmitting a signal, but it may still be a battery issue.
5. Battery Light
Some Hyundai key fobs have a small battery light indicator. If the battery light is illuminated or flashing, it’s a clear indication that the battery needs to be replaced.
6. Distance Test
If all the above tests yield positive results, perform a distance test to determine the strength of the key fob signal. Move away from your vehicle gradually and try to unlock the doors. If the doors unlock smoothly even from a distance, it indicates a strong key fob battery. However, if the doors fail to unlock or take longer to unlock as you move away, it’s a sign of a weak battery that needs replacement.
Troubleshooting Common Issues
If you’re experiencing problems with your Hyundai key fob, there are a few common issues you can troubleshoot:
1. The key fob is not responding
First, check if the battery is low. If it is, replace it with a new one. If the battery is not the issue, try resetting the key fob by following the steps in your owner’s manual.
2. The key fob is not unlocking or locking the car
Make sure that you are pressing the correct button on the key fob. If you are, try moving closer to the car and trying again. If that doesn’t work, try resetting the key fob.
3. The key fob is not starting the car
If the key fob is not starting the car, try moving the key fob closer to the ignition. If that doesn’t work, try resetting the key fob.

8. The key fob is not working after it has been wet
If your key fob has been wet, it is important to dry it out as soon as possible. Do not use a hair dryer or put it in the oven, as this could damage the key fob. Instead, place the key fob in a warm, dry place for 24 hours. Once it is dry, try using it again. If it still doesn’t work, you may need to replace it.
