How to flash cyanogenmod on SGS3(GT-I9300) 4.3 without a working volume up button?

Okay so.. just as the title says, i'm in quite a bit of a pinch right here. My Sgs3 volume up button isn't working( Not some software problem, it's hardware related), sooo i wonder if there is any option of flashing it whitout entering recovery mode, or if there is any way of entering recovery mode without volume up.
