A porta do vault, tem uma lock electrónica com 6 digitos?????
For safety reasons, external locked doors on commercial buildings have mechanisms for people on the inside to escape without using a key or combination. One common mechanism
uses an infrared motion detector to open an electronic lock for people moving towards adoor from the inside. Explain how an air gap under such an external door could be exploited
to open that door from the outside?
SOLUTION! Use a large warm metal sheet. Slide the sheet under the door and move it around to trigger the motion detector and unlock the door.
