Is your Hyundai Elantra key fob acting up? Before you rush to the dealership, a dying battery might be the culprit! This comprehensive guide will walk you through the simple steps to change the battery in your Hyundai Elantra key fob like a pro, saving you time and money.
Do You Need a New Key Fob Battery?
Key fobs are powered by small but mighty batteries that eventually wear out. Here are some telltale signs that it’s time for a replacement:
- Decreased range: You find yourself standing closer to your car to lock or unlock it.
- Intermittent functionality: The key fob works sporadically, requiring multiple button presses.
- Warning lights: Your Elantra’s dashboard displays a “Key Fob Battery Low” message.
What You’ll Need:
- A new CR2032 battery (easily found at most stores)
- A small flat-head screwdriver
- Optional: A plastic prying tool (to prevent scratching)
How to Change the Battery in Your Hyundai Elantra Key Fob:
Follow these easy steps to replace your key fob battery:
- Locate the release button: On the back of your key fob, find the small, recessed button.
- Release the mechanical key: Using the flat-head screwdriver or your fingernail, gently press the release button and slide out the mechanical key.
- Separate the key fob halves: With the mechanical key removed, you’ll see a small slot. Insert the flat-head screwdriver (or prying tool) into the slot and gently pry open the key fob casing.
- Replace the battery: Carefully remove the old CR2032 battery and install the new one, ensuring the positive (+) side faces up.
- Reassemble the key fob: Align the key fob halves and press them together until you hear a click, indicating they’re securely closed.
- Reinsert the mechanical key: Slide the mechanical key back into its slot until it locks in place.
Testing Your New Key Fob Battery
Once you’ve replaced the battery, test the key fob’s functionality by locking and unlocking your car’s doors and starting the engine. Everything working smoothly? You’re good to go!
