Ahh ... on weekends we need to input a PIN code on top of scanning . Well , let 's input the PIN ... Normally when I do this , I can hear the doors unlocking immediately . This time there was no response .
What will happen after the doors do not open ?
- They will go into their apartment with a key .
 - They will walk in unabated .
 - None of the above choices .
 - They will call building management .


They will call building management .
