1 Touch Locking is the padlock button, that can be turned on/off.
They should add another option for Code Locking on/off. That would turn off the possibility of the door locking with a code when it's already unlocked. That is a feature they should have, I've locked the door and gotten frustrated because someone unlocked the door to be helpful but it only caused more issues, sometimes the Forced Entry alarm is triggered.
