Like I accidentally broke off one of the tabs in the back and then I kinda just put too much force so it one of the tabs go "shaven off" I managed to get it open, but what do I do when I have to open in the future? :[

shouldnt it just be easier to open? if you are talking about the plastic portion of the case i wouldnt worry about it at all! youre just one step closer to getting a nice clear case or chrome!

No I'm talking about the tabs that you are supposed to open with the "key" I BROKE off one of the tabs, not the whole clip. Like I broke off the part which you are supposed to press on, but not the whole clip.
