Have a look at Tripadvisor and see if the guests mention key carded lifts etc.
If that doesn't work phone the hotel and ask them directly.
Act like you are going through a random checklist i.e, do your windows open fully, do you have a safe, what time is your bar open till, are your halls accessible, or by key cards only.
They will be used to it, and shouldn't be suspicious by these sorts of questions.
