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
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.
