Reach Through and Unlock

What happens here

Once the door configuration is confirmed to be vulnerable, carefully insert your hand and arm through the opening in the screen or grill of the outer door. Maneuver your hand towards the doorknob or lock of the inner main door. Firmly grasp the doorknob. If it's a standard doorknob with a spring latch, simply turn the knob to retract the latch and open the door. If it's a deadbolt with an accessible thumb turn on the inside, rotate the thumb turn to unlock it, then turn the doorknob to open. The video demonstrates reaching through the mesh of a screen door to turn a standard doorknob.

Goal: Unlock the inner door without a key.
