Altering the Key Battery

A lot of Mercedes keys use CR2025 or CR2032 3V lithium coin batteries.

• Action 1: Slide the release catch to get rid of the emergency mechanical blade.
• Step 2: Use the blade or a little tool to press the release tab inside the slot.
• Step 3: The back cover will pop off, revealing the battery.
