Title, I got to the summit and wanted to try the bondage machine on the right using a prisoner put on the conveyor belt (but she didn't move so I thought there was a bug and clicked on trying it myself since i didn't have any other slave); so now I'm stuck with tons of Cyber mitts, cuffs etc; how do I remove all of them? x) 

Ig there's a key somewhere but the places I've looked for, once i managed to move from the conveyor belt by clicking on an ally that was next to me, didn't have any of them. Do I have to wait for a guard to come instead? One did but he got caught by the trap and i killed him but there was no key.
