If we put them all together, maybe "exit" is the right word. Whether you 
  lock&leave or log-out, that's up to you. Either you exit your session 
and continue working, or you stop working and exit the room.
Don't know how well this translates, maybe "leave" can be translated, 
but in English "exit" is more recognized for these tasks.
