they have now locked the doors only the tenents have a key for. this is a safety risk that needs to changed. my dad lives there and sometimes i cant reach him by phone. he might have the ringer off etc.. i have no way of getting to him. what if he fell or something bad happened. no one could get to him. this is a safey violation and needs to be changed to possibly an intercom system. i am outraged. i can not reach my dad and dont know whats going on. how am i supposed to get to him????
