How to Find the Combination of a Number Lock Using a Shim
This educational animation demonstrates a method for bypassing a standard combination lock using a thin, flat tool known as a shim. By inserting the shim between the number wheels, the user can feel for a small notch or indentation on the internal cam of each wheel. When the shim drops into this notch, it indicates that the wheel is aligned correctly for the combination. By repeating this process for each wheel, the correct sequence can be identified. This visual guide highlights the mechanical vulnerabilities inherent in simple combination locks, emphasizing why they are not suitable for high-security applications.
