A consulting team is assessing a facility and discovers a secure door with a standard mechanical design. The team wants to open it gently to demonstrate any vulnerabilities in the building's security posture. Which approach is recommended to best address this situation?
Insert a magnet into the keyhole to neutralize the springs
Use a small pick and slight turning pressure to align each internal component
Cut the handle off with a metal saw to expose the mechanism
Hit the keyhole with a hammer until the mechanism loosens
Using a tension device and a small pick manipulates the internal mechanisms in a pin-and-tumbler cylinder without causing damage. This method systematically lifts each pin to align them at the shear line, allowing the cylinder to rotate. Techniques involving brute force, physical destruction, or improvised tools increase the likelihood of damaging the system and leaving obvious signs of tampering.
