I've done this a number of times. Remove the hard drive. Guide a flathead screwdriver under the space below the dvd drive coming from the gap where the sata drive was. If you look in the small gap on the side where the ear is against the dvd drive you can see the screwdriver tip. Push the tip against the bottom of the 'ear' and push it away from its locked position. Use your thumb on top of the ear as well so you push it slightly down to help the release of it. once you have it pushed free it will obviously lift. I sometimes have to do it to both left and right 'ear's. Good luck.
