So, I figured out my keurig lid issue. My hubby opened it too hard & too far back. I took it apart after he left for work & those 2 long plastic pieces that are on each side of where the k-cup goes MUST be inside those tracks. If u open it too hard they will pop out & prevent the lid from opening any further & from shutting.
The plastic pieces have lips on the bottom so just pop those back in the tracks & ur good to go!!
