These prongs are part of the camera case, and are used to attach the camera to all GoPro mounts, so when you detach the camera, they will come off the mount with it. [2] X Research source
This should be a smooth process without requiring much force, so if you are struggling you may need to pinch the prongs harder. [3] X Research source
The latch is the entire raised surface on the top of the case, with the edge along the front of the camera shorter than the edge along the back. If you look carefully you should be able to see the two hooks on the long edge holding the back of the case shut. For this step, imagine these hooks as acting as a hinge for the latch. With the GoPro HERO 3 cases, there is a button on the top of the latch to lock it down with a white arrow on it, and another arrow on the front right corner of the latch for the secondary release. [5] X Research source Slide the button into the empty space beside it and hold it there to unlock it, then press the corner button and pull upwards to open the latch. This should be a relatively easy process involving little to no force.
This door is removable at the hinge, so be careful when you do this to make sure it stays together; you don’t need to take it off completely to access your camera.
You may need to grab it with your fingertips and tug lightly, otherwise just be ready to catch it when it slides out.
