This reminds me of when I was in Hawaii visiting my brother who lived in a high rise building. This was years ago so all I had ever know was the lock and key but his building had key cards and the doors would just unlock with the swipe of a card and you could go to your unit. He explained they are just magnetically locked. I asked well couldn't you just pry them open? We decided to try and sure enough with 2 of use we were able to pull past the strong electromagnet. It didn't really seem overly hard I am sure a strong person could do it alone.
