Step-by-Step Guide to Change the Key Fob Battery
Follow these simple steps to change the battery in your Mercedes Benz key fob:
Step 1: Find the Battery Compartment
The first step is to locate the battery compartment on your key fob. The exact location may vary depending on the model and year of your Mercedes Benz, but it is typically located on the back of the key fob. Look for a small indentation or a groove on the side of the key fob.
Step 2: Open the Key Fob
Using a small flathead screwdriver or a similar tool, carefully pry open the key fob. Insert the screwdriver into the groove or indentation and gently twist it to separate the two halves of the key fob. Be cautious not to apply too much force to avoid damaging the key fob.
Step 3: Remove the Old Battery
Once the key fob is open, you will see the battery inside. Take note of the battery’s orientation so that you can insert the new battery correctly.

With the new battery in place, line up the two halves of the key fob and press them together firmly. You should hear a click or feel the key fob snap shut. This indicates that the key fob is securely closed.
