The pin code always disarm the system

Hi. I need the option to set a pin code for the entrance which won't disarm the system. My daughter is 5 years old and think that all people around her friends, that's why she is telling them everything including the pin code from door. I want that she be able to enter home, but  I need that this code doesn't disarm the system. Here is a huge reason why:

if she shared this code with someone else that person able to open our house and disarm the system at the same time and in best case we will be robbed, but what if it will happen at night while we are sleeping?! We can be killed, kids can be kidnapped!!! Without this option your system is useless and doesn't protect us!!! Please, create the option to choose if pin code disarm the system or not ASAP. 

Hope for your understanding, thank you.
