Replacing the key fob battery in your 2013 Hyundai Sonata is a quick and easy task that can save you time, money, and frustration. This guide will walk you through the process, offering expert advice and troubleshooting tips to ensure your key fob is back in perfect working order.
Identifying a Dying Key Fob Battery
Several signs indicate your 2013 Hyundai Sonata key fob battery is failing. Reduced range is a common symptom. You might find yourself having to stand closer to your car to lock or unlock it. Another sign is a weaker signal strength. The car might take longer to respond, or you might have to press the buttons multiple times. Sometimes, the key fob might not work at all.
