I was trying to get the pressure plate secret in the Pyramid to work when the rock I threw north hit the back wall of the pressure plate as the gate closed and now I can't reach it through the bars, and I can't lift the bars because the pressure plate needs to be reset. Unfortunately, my last save before this was 4 hours ago.

Does anybody have a clue how I can get the rock off the plate or did I just ruin my chance to get that secret? I'm willing to use console commands, I don't care at this point. I remember a special pair of items from the Maze of Madness that would easily fix this. Is there a way to spawn those? That's the only solution I can think of at this point without redoing 4 hours of hard work.
