Since you mention 2 or 3 floors in a building. You might want to look more into the dog type devices. i have both an erostek 301 and a 302, and on a clear line of sight around 80 feet seems max range. But i can go into the laundry room at home , which is only 30 feet from the remote, and it is spotty if it receives the singal at all. I would think the transmitters for the dog collars have a bit more power then the small keychain remote. check the range for them, they probably all vary to some degree
