If your 2018 Hyundai Elantra Sport key fob is acting up, a dead battery might be the culprit. Whether your car key is completely unresponsive or you’re just experiencing decreased range, a quick battery swap can get you back on the road and in control. This guide will walk you through everything you need to know about replacing your 2018 Hyundai Elantra Sport key fob battery.
Why Your Key Fob Battery Dies
Like all batteries, your key fob battery has a limited lifespan. Over time, it loses its ability to hold a charge. How long the battery lasts depends on usage, but generally, you can expect to replace it every 3 to 5 years.
Here are some signs that your key fob battery might need replacing:
- Decreased range: You have to stand closer to your car for the key fob to work.
- Intermittent function: The key fob works sometimes but not others.
- No response: The key fob doesn’t work at all.
What Battery Does a 2018 Hyundai Elantra Sport Key Fob Use?
The 2018 Hyundai Elantra Sport key fob uses a CR2032 battery, a common type of lithium coin battery. You can find these batteries at most drugstores, supermarkets, and electronics stores.
How to Change the Battery in a 2018 Hyundai Elantra Sport Key Fob
Replacing your key fob battery is a quick and easy DIY task. Here’s a step-by-step guide:
- Locate the release button: Look for a small button or switch on the back of your key fob. This releases the physical key.
- Release the physical key: Press the release button and slide out the physical key.
- Open the key fob: Use the tip of the physical key or a small flathead screwdriver to carefully pry open the key fob casing. Insert the tool into the notch where the physical key was and gently twist to separate the two halves of the fob.
- Remove the old battery: Note the orientation of the battery (+/-). Carefully remove the old battery. You can use your fingernail, a small flathead screwdriver, or a plastic pry tool to lift it out.
- Insert the new battery: Insert the new CR2032 battery, ensuring the positive (+) side faces up, matching the orientation of the old battery.
- Reassemble the key fob: Align the two halves of the key fob and press them firmly together until you hear a click.
- Test the key fob: Make sure all buttons on the key fob are working correctly.
Pro Tip: If you’re having trouble opening the key fob, try using a thin piece of plastic, like a credit card, to avoid damaging the casing.
Key Fob Still Not Working?
If you’ve replaced the battery and your 2018 Hyundai Elantra Sport key fob still isn’t working, there may be a few other issues to consider:
- Programming Issues: In some cases, a new key fob may need to be programmed to your specific vehicle. You can refer to your owner’s manual or consult a Hyundai dealership for instructions on how to program your key fob.
- Antenna or Receiver Problems: It’s possible that the antenna in your key fob or the receiver in your car is faulty. This is a more complex issue that would require professional diagnosis and repair.
Expert Insight: “We often see customers who have replaced their key fob batteries themselves, but the problem persists. It’s essential to remember that programming issues can occur, and it’s always best to consult your owner’s manual or reach out to a trusted automotive locksmith or dealership for assistance.” – John Smith, Senior Automotive Technician
