trunk
To replace the trunk lid springs on a 1999 Mercedes, first, safely support the trunk in an open position using a prop or assistant. Remove the old springs by detaching them from their mounting points, typically using a flathead screwdriver to release the clips or hooks. Install the new springs by securing them to the same mounting points, ensuring they are properly seated. Finally, test the trunk operation to ensure the springs are functioning correctly.

The battery is in the trunk on the right side. You just remove it and replace it with the new one.
If I remember correctly you need to turn the key and press it in to get it to open. Good luck
I have a 1987 Mercedes that has no trunk key. Do I remove the back seat to get in?
