I sometimes intentionally don't want to have my character get up to get the door and just play it off as maybe they have a way to remotely open it from other parts of the room. Maybe it's a nearby access panel or tied to controls on a TV remote? Figure either way, there's some amount of reasonable flexibility on it, given available technology.
Similar for why I can 'peek' without getting up. Given the prevalence of cameras and other tech, maybe there's a small screen attached to a really basic cam to easily check that instead of a physical peep hole? But because it's such a cheap one, that's why it can't be linked in like other more sophisticated (secure tech) cams.
