text: Ivy: What's the door code?
  Dawn: 4537
  Adrian: it's the apartment number followed by the key button followed by 4537
  Ivy: I don think it's working. I'm calling the apartment
  Dawn: Maybe you wait too long before pushing the key button  - it calls the apartment after 3 seconds
  Ivy: ok
  Ivy: ok it worked this time
  Dawn: and inside it's the 3rd floor
  Ivy: thanks ;)
  Adrian: good luck
target: The door code is the apartment number followed by the key button followed by 4537. The entry phone calls the apartment 3 seconds after pushing the apartment number. The apartment is on the 3rd floor.
