Finding the Right Battery for Your Hyundai Key Fob

Most Hyundai key fobs use a standard CR2032 battery, a small, coin-shaped lithium battery readily available at most stores. However, checking your owner’s manual or searching online for your specific Hyundai model is always a good idea. Using the correct battery ensures optimal performance and prevents potential damage.
