[MacBrody]

To replace the battery in a Mercedes-Maybach 57 key, follow these steps: 1. Before replacement, identify the battery model required for the car key and select a new key battery according to the specified model. 2. Push the marked switch upwards from the bottom of the key, and the hidden mechanical key will pop out slightly, allowing you to remove it. 3. Use the extracted mechanical key to press against the marked position and gently pry open the key casing. 4. Once the casing is removed, you will find the battery positioned deep inside. Insert a toothpick into the gaps on both sides and gently pry to remove the old battery. 5. When installing the new battery, ensure the positive and negative poles are correctly aligned. Reassemble the key following the original steps to complete the process.
