Replacing your 2016 Mercedes key fob battery is a straightforward process that can save you a trip to the dealership. Follow these instructions:

1. Identify Battery Type: Locate the owner’s manual or search online for your specific Mercedes model to determine the correct battery type. Most 2016 models use a CR2025 or CR2032 battery.
