Hyundai Battery Replacement Key Fob

Replace your Hyundai key fob battery to avoid being stranded.

Maintaining the battery will help extend the longevity of your key fob.

Identifying the Problem

analyzing root causes thoroughly

If your Hyundai key fob isn't working well, you may need to change the battery. Signs include a shorter range or no response. First, check you're close enough to the car without anything blocking the signal. If there's no improvement, the issue mightn't be the battery.

Using a spare key fob can help identify the problem. If the spare works fine, then the main key fob's battery likely needs replacement. But, if neither key fob works, the problem might be with the car's receiver or another part, not the key fob batteries.

Check the key fob for any damage or wear that might stop it from working. A key fob that's been dropped might've internal damage that affects its function, even with a new battery.

Choosing the Right Battery

To ensure your Hyundai key fob works well, select the correct battery type and size. Hyundai key fobs typically need CR2032 or CR2025 lithium coin batteries, available in electronics stores.

Here's a guide for Hyundai key fob battery types:

  • Hyundai Sonata (2015-2020): CR2032
  • Hyundai Elantra (2017-2020): CR2032
  • Hyundai Tucson (2016-2020): CR2025
  • Hyundai Santa Fe (2013-2020): CR2032

Check your owner's manual or the existing battery in your key fob for the right type, usually indicated on the battery itself.

Choose high-quality batteries to avoid leaks and damage to your key fob. Good batteries last longer and ensure your key fob remains reliable.

This information helps you pick the correct battery, making replacement easier and keeping your Hyundai key fob functional.

Troubleshooting Common Issues

If your Hyundai key fob isn't working after changing the battery, check a few things:

  1. Make sure the new battery is in the right way, with the positive side up, and fits well.
  2. If the key fob was dropped or wet, its inside parts might be damaged. You can't fix this yourself, but knowing what's wrong helps when you get it repaired.
  3. If your key fob works sometimes but not others, it could be because of interference from other devices like phones or Bluetooth gadgets. Try using it away from these devices.
  4. If the key fob's range is shorter, the new battery might be weak or old. Try a new, high-quality battery from a trusted brand.

Maintaining Your Key Fob

key fob care tips

To keep your Hyundai key fob working well, do these three things:

  1. Clean it: Key fobs get dirty from being in your hands, pockets, or purse. Wipe it with a soft cloth and alcohol-based cleaner. Be careful not to get liquid inside it.
  2. Change the battery often: If your key fob starts responding less, it might be time to change the battery. Most use a CR2032 battery. Replace it every 1-2 years for best performance.
  3. Keep it away from extreme temperatures: Don't leave your key fob in very hot or cold places. Extreme temperatures can damage its parts and battery.
