Do you mean as in the drive is stuck shut or it won't open when you hit the open button?
Nearly All CD/DVD drives have a little hole on the front of it that, when pushed with say either a toothpick or a paperclip that has been straightened, will override the cd/dvd drive and open it for you. Unless it's stuck shut, then you'll have to do some risky manual labor
