Smart key won't lock, unlock doors, or open the trunk

What is your question?

Hi, I have a 2011 Mercedes SL550. My smart key won't lock or unlock the doors, or open the trunk. I also can't open the trunk from the inside using the trunk relaese button. It appears that the seat massager is not working either. I haven't tried to put the top down as of yet.
