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.Would you believe it, sat in the back, key in pocket, rear side window opened and closed without a problem!!
