Understanding Your Hyundai Elantra Key Fob
Before we dive into the replacement process, let’s take a moment to understand the different types of Hyundai Elantra key fobs. Over the years, the design has evolved, but the basic functionality remains the same. Whether you have a traditional key fob, a smart key, or a proximity key, the battery replacement process is generally similar. Recognizing the type of key fob you have will help you locate the correct battery and follow the right steps.
