NEW Mercedes Benz key fob battery replacement - EASY DIY

Here is the brand new Mercedes Benz key fob for the new S-Class. You don't need any tools to perform the battery change. First get your new 2032 to replace your dead / weak battery. Then remove the mechanical key by pressing the back button and pulling out the key. Then use that key to pry the back cover off. After the back cover is off, use the mechanical key to open the battery door hatch. Replace your battery then close the hatch back up. Snap in the black back of the fob, slide your mechanical key back in and you're good to go!

I don't understand why Mercedes wants me to come into the dealership to have my key fob battery changed.
