Want to change your Mercedes key fob battery yourself or fix a sticky button? Disassembling your Mercedes key fob might seem daunting, but it’s simpler than you think. Whether you’re a DIY enthusiast or just looking to save a trip to the dealership, this guide will walk you through the process step-by-step. Let’s get started!
Understanding Your Mercedes Key Fob
Before we dive into disassembly, it’s important to know what type of key fob you have. Mercedes has used various designs over the years, each with its own quirks. Generally, you’ll encounter two main types:
- Flip Key: These fobs feature a metal key that folds into the fob body.
- Chrome Smart Key: Sleeker and more modern, these fobs have their keys hidden within and often feature a panic button on the back.
Knowing your key fob type will help you identify the correct disassembly points and avoid potential damage.
Gathering Your Tools
Don’t worry, you won’t need a mechanic’s toolbox for this job! You’ll only need a few basic tools:
- Small flathead screwdriver: Choose one with a thin tip to avoid scratching your key fob.
- Plastic pry tool (optional): This will help prevent damage to the fob’s casing.
- Soft cloth or microfiber towel: This is for protecting your key fob from scratches and for cleaning.
Disassembling Your Mercedes Key Fob: A Step-by-Step Guide
The exact disassembly procedure may vary slightly depending on your specific key fob model. However, the general steps remain similar:
Step 1: Locate the Release Button or Notch
Examine your key fob carefully. Most Mercedes key fobs have a small release button or notch located on the side or back. This button releases the metal key blade.
Step 2: Release the Metal Key
Press the release button or insert your flathead screwdriver gently into the notch and apply light pressure. The metal key should slide out partially or fully.
Step 3: Separate the Key Fob Halves
With the metal key removed or extended, you’ll notice a seam running around the edge of your key fob. Carefully insert your plastic pry tool or flathead screwdriver into the seam and gently pry the two halves apart. Start at the key slot and work your way around, being careful not to use excessive force.

Step 4: Access the Battery or Internal Components
Once separated, you’ll see the battery compartment or the key fob’s internal circuit board. If replacing the battery, note the type and orientation for proper installation.
Expert Insight from John Miller, Senior Automotive Technician:
“Always use caution when prying open the key fob to avoid damaging the internal components or the casing. If you encounter resistance, double-check that you are prying at the correct seam.”
Reassembling Your Mercedes Key Fob
Reassembling your key fob is basically the disassembly process in reverse:
Step 1: Align and Snap the Halves Together
Carefully align the two halves of the key fob, making sure all the internal components are properly seated. Press the halves together firmly until you hear a satisfying click, indicating they are securely fastened.
Step 2: Reinsert the Metal Key
Slide the metal key back into its slot until it locks into place.
Step 3: Test Your Key Fob
Before you call it a day, test all the buttons on your key fob to ensure everything is functioning correctly.
