I don't know. Looks like you have cover latch catches that may go through the panel and into the bracing below. May have to remove those screws as well. You'll have to comb the carpet all the way around and see if you've missed any. Try tapping the edges with a rubber mallet to see if you can get an edge loose. Keep us posted on your progress.

Do you know anyone with small hands that could reconnect for you?
