You’ll see just how easy it is to remove the lid when you get you new one, but once all the chaff is out of the way, just open the retainer bar 1/2 way and slide it half way out to the left. At that point “Gingerly” pop the latches around the edges (as I said when you get your new one from “ALiExpress”(tm) ) you’ll easily see just what tabs hold the broken lid on and your new one on. Enjoy your DIY experience
