How to Replace the Battery in the New Mercedes-Benz GLS63 Key?

[DeDaniel]

To replace the battery in the Mercedes-Benz GLS63 key, follow these steps: 1. Turn the key to its tail end, where there is a push button. Push it upwards, and the metal key inside will pop out. Remove the key. 2. There is a gap at the tail end of the key. Use a tool to pry it open with slight force, and the outer shell of the key will open. 3. After opening the shell, the key is positioned deep inside and cannot be removed by hand. Use a thin object to slide along the side gap and pry upwards to remove the old battery, then replace it with a new one. 4. After replacing the battery, ensure to check it, making sure the positive side is facing upwards. 5. Once the battery is securely in place, insert the shell back to cover it, and then reinsert the mechanical key.
