I’ve not tried them. It makes good sense that they work without the key since you’ll be in bed when ever you might want to open the windows, I just wish I could open the rear door window from inside.. I know you can re-programme the key but I’m usually drunk by then so the key isn’t in the ignition and it’s not on me either.
I find the switch in the back for the rear window very temperamental. It works sometimes but not all the time. Nothing to do with ignition key in/not in, child lock on/not on.
