Hyundai Elantra key fobs drain batteries monthly on Hyundai Elantra

Some Hyundai Elantra owners report experiencing frequent key fob battery drainage, with some needing replacements monthly. This issue can be exacerbated by storing the key fob too close to the vehicle, as being within 15-20 feet or inside the car may lead to the fob being polled by the car's computer, resulting in battery depletion. Additionally, using low-quality batteries can further contribute to the problem. Owners are advised to bring their key fobs to the dealer for inspection and battery replacement under warranty, and keeping records of battery lifespan may assist in diagnosing recurring issues.
