Identifying a Dead Key Fob Battery
How do you know if it’s truly a dead battery? Here are some telltale signs:
- Reduced Range: Notice you have to be much closer to your car for the key fob to work? This is an early sign of a weakening battery.
- Intermittent Functioning: Does your key fob sometimes work and sometimes not? A dying battery can cause erratic behavior.
- No Response at All: This is the most obvious sign. Your key fob is completely unresponsive, leaving you stranded.
What to Do When Your Hyundai Elantra Key Fob Battery Dies
Don’t panic! Even with a dead key fob battery, you can still get into your car and get it started.
Getting Into Your Car
Most Hyundai Elantras have a hidden key inside the key fob. Look for a small release button or switch. Press it, and a small metal key blade should slide out. You can use this key to manually unlock the driver’s side door. Some models might have a keyhole hidden behind a cap on the door handle.
Starting Your Car
Once inside, you might be able to start your car even with a dead key fob battery. Some Elantras have a designated spot near the steering column or in the center console where you can place the key fob. This allows the car to detect the immobilizer chip inside, even if the battery is dead. Consult your owner’s manual for the specific location in your model.

Replacing the Key Fob Battery
Replacing the key fob battery is a simple DIY task. Here’s a step-by-step guide:
- Gather Your Tools: You’ll need a small flat-head screwdriver and a new CR2032 battery (this is the most common type for Hyundai Elantra key fobs, but double-check your owner’s manual to be sure).
- Open the Key Fob: Carefully insert the flat-head screwdriver into the notch or seam on the side of the key fob and gently pry it open. Be careful not to damage the plastic casing.
- Locate the Battery: Inside, you’ll see the small, round CR2032 battery.
- Remove the Old Battery: Gently pry the old battery out using the screwdriver.
- Install the New Battery: Insert the new battery, making sure the positive (+) side is facing up.
- Close the Key Fob: Snap the two halves of the key fob back together.

What if the Key Fob Still Doesn’t Work?
If you’ve replaced the battery and your Hyundai Elantra key fob is still unresponsive, here are a few things to check:
- Try a Different Battery: Sometimes, new batteries can be faulty. Try a different CR2032 battery to rule this out.
- Check the Key Fob Contacts: Make sure the metal contacts inside the key fob are clean and free of corrosion. You can clean them with a cotton swab and rubbing alcohol.
- Consider Key Fob Reprogramming: In rare cases, the key fob might need to be reprogrammed. You can usually do this yourself by following the instructions in your owner’s manual. If you are facing key fob programming challenges for other models like the Sonata, we have resources like 2015-hyundai-sonata-key-fob-programming which might be helpful. Otherwise, you might need to take your car to a Hyundai dealership or a qualified locksmith.
- Check for other issues: Sometimes the problem isn’t the key fob at all. A failing car battery, for example, can mimic symptoms of a dead key fob.
