u/Bulipen

I started a freelancer campaign near the vault area in New York and as I'm looking for chloroform, I thought about this doorway that has a keycard scanner and how I didn't want to run the entire way just to get back to the security room (I didn't have a scrambler in my safehouse), So I wondered whether or not this trick would work, apparently it does, Is this a well known thing or am I the only one who didn't know you can force doors to stay open using a suitcase?
