If your Hyundai key fob is acting up – locking/unlocking erratically or not responding at all – a dead battery is likely the culprit. Thankfully, replacing the battery in your Hyundai key fob is a quick and easy process you can do yourself, saving you a trip to the dealership. This comprehensive guide will walk you through each step, ensuring you get back on the road with a fully functional key fob in no time.
What You’ll Need for Hyundai Key Fob Battery Replacement
Before you begin, gather the following items:
- A new CR2032 battery: This is the standard battery type for most Hyundai key fobs.
- A small flathead screwdriver: This will be used to pry open the key fob casing.
- Optional: A small tray or container: This can help prevent losing the small parts during disassembly.
Steps to Change the Battery in your Hyundai Key Fob
While the exact procedure may vary slightly depending on your specific Hyundai model and year, the general steps are relatively similar:
- Locate the Key Fob Release Button: This button is usually located on the back of the key fob, near the key ring hole.
- Release the Mechanical Key: Press the key fob release button and gently pull out the mechanical key from the fob.
- Open the Key Fob Casing: Use the small flathead screwdriver to carefully pry open the key fob casing. Insert the screwdriver into the seam where the two halves of the fob meet, and gently twist to separate them.
- Identify and Remove the Old Battery: The CR2032 battery is usually located in a designated compartment within the key fob. Carefully remove the old battery by prying it out with the screwdriver. Note the battery’s orientation for correct replacement.
- Insert the New Battery: Align the positive (+) side of the new CR2032 battery with the positive (+) marking in the battery compartment. Gently press it into place.
- Reassemble the Key Fob: Align the two halves of the key fob casing and press them together firmly until you hear a click, indicating they are securely closed.
- Reinsert the Mechanical Key: Slide the mechanical key back into its slot on the key fob.
- Test the Key Fob: Try locking and unlocking your car doors, and starting the engine to ensure the new battery is working correctly.
Troubleshooting: Key Fob Still Not Working?
If you’ve replaced the battery and your Hyundai key fob is still not working, here are a few things to check:
- Battery Orientation: Double-check that you inserted the new battery with the positive (+) side facing up.
- Battery Contacts: Inspect the battery contacts inside the key fob for any dirt or corrosion. If present, carefully clean them with a cotton swab and rubbing alcohol.
- Key Fob Programming: In some rare cases, you may need to reprogram your key fob after replacing the battery. Consult your owner’s manual or contact a Hyundai dealership for instructions on how to do this.
- Other Issues: If none of the above solutions work, there might be a more significant problem with your key fob or car’s immobilizer system, requiring professional diagnosis and repair.
