Understanding Your Mercedes Key Fob

Mercedes key fobs have evolved over the years, featuring sleek designs and advanced technology. However, the method to access the battery compartment remains relatively consistent. Before we dive in, let’s identify some common features:

Mechanical Key Slot: This slot releases the physical key, useful for emergencies like a dead key fob battery.

Release the Mechanical Key: Press the emergency key release button and gently slide out the mechanical key.
Identify the Battery Compartment: With the mechanical key removed, examine the key fob for a small tab or a sliding cover. This usually indicates the battery compartment.
Open the Compartment:
- Tab Release: If you see a small tab, gently pry it open with your fingernail or a small flat-head screwdriver.
