This comprehensive guide will walk you through the process of opening a Mercedes key fob, covering different models and common issues you might encounter.
Understanding Your Mercedes Key Fob
Before you start prying your key fob open, it’s important to understand the different types and generations of Mercedes key fobs. Some key fobs have a visible emergency key slot, while others have a hidden release button. Identifying your key fob type will help you determine the correct opening method.
Here’s a quick breakdown:
- Chrome Key Fobs: These key fobs are sleek and stylish, often featuring a silver or chrome finish. They typically have a release button on the back for ejecting the emergency key.
- Plastic Key Fobs: These key fobs are more common on older Mercedes models. They usually have a small notch or groove where you can insert a flat object to pry open the casing.

Tools You May Need:
- Small flathead screwdriver
- Fingernail or a thin plastic pry tool
Instructions:
- Locate the release button or notch: Examine your key fob carefully. If you see a small button on the back or side, that’s likely the release for the emergency key. If you see a notch or groove running along the edge of the key fob, that’s your starting point for prying it open.
- Release the emergency key (if applicable): Press the release button and gently pull out the emergency key. This will give you better leverage when opening the key fob.
- Insert the flathead screwdriver (or pry tool): Carefully insert the tip of the screwdriver into the notch or groove. Be gentle and avoid applying excessive force.
- Gently pry open the casing: Slowly twist the screwdriver to release the clips holding the key fob together. You should hear a slight click as each clip disengages.
- Separate the two halves of the key fob: Once all the clips are released, carefully separate the two halves of the key fob. Be mindful of the internal components and avoid touching the circuit board.
Note: Some Mercedes key fob models might have slight variations in design. If you encounter resistance or are unsure about a particular step, consult your owner’s manual or seek assistance from a qualified Mercedes technician.
