Often times, they won't change the password or key slot to unlock the settings and you can just give yourself a free cycle. That's what I do
applies to anything with a passcode or secret menu tbh. Building access control/intercom panels especially I've noticed. Though it seems like it would get you kicked out if they ever notice. Depends how oblivious the owners are ig.
I heard they did this near me and all got arrested after like one night, occupying an outdoor area. Glad other places are more organized!
