Different Types of Mercedes Key Fobs
Mercedes has released several key fob designs over the years, each with a slightly different opening mechanism. Understanding your specific key fob type is the first step to opening it correctly. Some older models feature a small release button or switch, while newer “smart keys” might have a hidden emergency key blade release. Don’t worry, we’ll cover them all!
Locating the Release Button or Switch
Most Mercedes key fobs have a small release button or switch. This is typically located on the side or back of the fob. Look closely for a small indentation or button, often marked with a key symbol or a small lock icon. This is your target!

Once you’ve located the release button, press it firmly. While holding the button down, gently slide or pull the key fob apart. You should feel the two halves separate, revealing the internal components like the battery and, in some cases, the emergency key blade. Remember to be gentle to avoid damaging the fob. open mercedes key fob
What if My Key Fob Doesn’t Have a Release Button?
Some newer Mercedes key fobs, particularly the “smart key” designs, may not have a visible release button. These often incorporate a hidden emergency key blade release.
Accessing the Emergency Key Blade
Look closely for a small release tab or switch, usually located on the side of the key fob. Press this tab and the emergency key blade will slide out. This key blade can be used to unlock your car door manually in case of a key fob malfunction. Once you have the key blade out, you can often use it to pry open the key fob itself, revealing the battery compartment.
