I pried one side open slightly from the corner nearest the batteries and put in a paper clip, then worked the other side the same way and placed a paper clip in, and then worked my way across the edge alongside the battery storage. From there, the cover is also glued internally about an inch in on both sides of the circuit board, so I placed a thin screwdriver in and separated one side and then the other. After that, I placed the screwdriver between the silicone in the center and the case, NOT between the silicone and the chip, and magically the case lifted off. Lifting the lid from battery storage side first, none of the retaining tabs on the other side broke. The torx adjustment screw was tight however, must have been siliconed also to prevent movement. Got it tightened by adjusting clockwise, and cleaned the rubber covers on the bottom of the panel as well as cleaning where the covers touch the spring loaded pad with rubbing alcohol, dirtied with food and dust/dirt. And VOILA! Works perfect. Thanks.
