Our new landlord changed the front door lock to a key fob system last year. Recently we had a power outage in the building and the key fob system didn't work. The front door stayed locked and tenants couldn't get in. Does the law require a back up system for key fobs? The landlord doesn't seem to care that a power outage means we are locked out of our building (unless we can contact someone in the building via phone to let us in). This seems dangerous if it happens in the middle of the night. During this recent power outage it took 3 hours for maintenance to show up.
Thanks!
