Maintaining your Hyundai’s key fob is crucial for convenient and secure vehicle access. Over time, the battery in your key fob may deplete, hindering its functionality. Replacing the battery is a simple yet essential task that can be easily accomplished by following these clear and informative steps. Whether you’re dealing with a fading signal or intermittent button responses, a battery replacement will restore your key fob’s reliability and keep your Hyundai running smoothly.
Before embarking on this task, gather the necessary materials: a new CR2032 battery and a small, flat-head screwdriver. Locate the key fob’s release button, typically situated on the back or side of the device. Press the button to detach the metal key and reveal the battery compartment. Carefully insert the screwdriver into the designated slot and gently pry open the compartment. Remove the old battery and dispose of it properly. Align the new battery correctly, ensuring the positive (+) side faces upward. Securely close the compartment and reattach the metal key. Your Hyundai key fob is now ready for action, providing you with seamless access to your vehicle.
It’s important to note that battery life can vary depending on usage patterns and environmental factors. If you find yourself frequently replacing the key fob battery, consider consulting a qualified automotive technician to identify any underlying electrical issues that may be causing premature battery depletion. Additionally, avoid exposing your key fob to extreme temperatures or excessive moisture, as these conditions can accelerate battery degradation. By following these simple steps and taking proper care of your key fob, you can ensure its optimal performance for years to come.
Identifying the Battery Type
Knowing the battery type in your Hyundai key fob is crucial for a successful replacement. The battery used in Hyundai key fobs primarily varies depending on the model and year of your vehicle, making it essential to identify the correct type.
First, consult your vehicle’s owner’s manual to find the designated battery type. This information is typically found in a specific section dedicated to key fob maintenance. If you no longer have access to the manual, you can contact your local Hyundai dealership or an automotive technician for assistance.

Once you’ve opened the key fob, you’ll find the battery nestled within. Carefully remove the battery and examine its label or imprint, which will display the specific type, such as CR2032 or CR2016.
