Experiencing issues with your Hyundai Ioniq key fob? A common culprit is a low battery. If you’ve encountered a “key not detected” message on your dashboard, especially when trying to start your vehicle, it might be time for a battery replacement. Don’t worry, this is a straightforward task you can easily handle yourself, ensuring you’re not stranded unexpectedly.
To keep your Hyundai Ioniq running smoothly, knowing the correct battery type for your key fob is essential. For the 2020 Hyundai Ioniq HEV, and potentially other models and years (always double-check your user manual for definitive information), the key fob typically uses a CR2032 3V lithium battery. This type of battery is widely available at most drugstores, supermarkets, and online retailers. Having this information readily available saves time and prevents frustration when your key fob battery eventually needs replacing.

Replacing your Hyundai Ioniq key fob battery is a simple process that requires no special tools. Here’s a quick step-by-step guide:
- Locate the notch: On your key fob, find the small notch, usually located on the side or bottom of the fob casing.
- Open the fob: Use a small flathead screwdriver or even a coin to gently pry open the fob casing at the notch. Be careful not to scratch the plastic.
- Identify the battery: Once open, you’ll see the CR2032 battery. Take note of its orientation (+ side up).
- Remove the old battery: Carefully remove the old battery. You can use your fingernail or the tip of a pen to gently lift it out.
- Insert the new battery: Install the new CR2032 battery, ensuring the + side is facing upwards, matching the orientation of the old battery.
- Close the fob: Snap the key fob casing back together until it’s securely closed.

It’s wise to proactively replace your key fob battery periodically, even before you encounter issues. Consider replacing it every 1-2 years as preventative maintenance. Furthermore, as the original poster wisely suggested, keeping a spare CR2032 battery in your car, perhaps in the glove compartment or owner’s manual packet, can be a lifesaver. Imagine being in a remote location and facing a dead key fob battery – having a spare readily available eliminates potential headaches and ensures you can get back on the road quickly. Don’t let a dead key fob battery disrupt your journey. Be prepared and keep your Hyundai Ioniq key fob battery fresh!
