I don t think Dean will unlock the cage to try to kill Lucifer to escape the mark.

First Death Scythe can kill Lucifer, but how will dean come closer to use it , lucifer is one of the most powerfull being in the show , he can only snap his finger and dean is dead if he see him

Second, if he try to kill Lucifer opening his cage and faild , Lucifer is a lot worse for the world than him becoming Knight of Hell.
