peephole lock picking, operates on a simple yet highly efficient principle. The following is a detailed breakdown of this technical principle:
Step 1: Removing the peephole
The first and crucial step in peephole lock picking is to remove the peephole from the security door. The peephole, originally designed to enhance residential security, ironically becomes a security vulnerability. Criminals use specialized tools, such as peephole pliers, which are intricately designed to effortlessly remove the peephole without causing undue attention or damaging the door. After the peephole is removed, a small hole with a diameter of approximately 2 centimeters is left on the door, serving as the "keyhole" for subsequent operations.
Step 2: Inserting the Special Tool
Once the peephole has been successfully removed, the criminal will swiftly produce a specially crafted "L"-shaped tool. This tool is no ordinary item; it comprises several thin steel tubes nested within each other, with flexible joints that allow it to adapt to different door thicknesses and angles. At the tip of this tool, there is a meticulously designed plastic hook, which is shaped and sized to precisely engage the lock lever inside the door. The criminal will then carefully insert the thin tube portion of the tool through the peephole hole into the door interior, until the hook at the tip is able to reach and engage the lock lever.
Step 3: Operating the Tool to Lockpicking
With the special tool's hook successfully engaged with the lock lever, the criminal will begin to apply pressure on the tool's handle from outside the door. Due to the "L"-shaped design of the tool, this setup ingeniously achieves force transmission and conversion. As the external handle is pressed downwards, the hook inside the door also receives a downward force, thereby depressing the lock lever. Under normal circumstances, this unlocking action would require a key or a password, but now it is achieved through a simple "L"-shaped tool. The entire process is swift and covert, typically taking only a few seconds to complete, and is difficult for outsiders to detect.
