Is your 2016 Mercedes Benz key fob acting up? Before you schedule a pricey dealership visit, consider this: a dying battery is often the culprit behind a malfunctioning key fob. Luckily, replacing it is a surprisingly simple DIY task that can save you time and money.
Recognizing a Dying Key Fob Battery
Several signs indicate your 2016 Mercedes Benz key fob battery might need replacing:
