About and are the addresses for the new blog as part of My associates and I will focus on topics that relate to the insecurity of locks, safes, hardware, consumer products and systems that are ostensibly designed to protect you but may not do what they represent. You may find related articles about the insecurity of products written by Marc Tobias at

Whereas primarily serves security professionals with extensive and often restricted databases about locks and safes, this blog will talk about and detail security vulnerabilities that primarily affect the consumer and commercial sectors. There is a great deal of hype in the security industry by manufacturers and other “experts” and an equivalent lack of understanding by the public as to what is and what is not secure. We will spotlight shoddy products, poor, negligent, or inept designs, and the lack of candor by some hardware manufacturers regarding security issues and what they sell.

This is a personal column; the new media for communicating information in the twenty-first century. Improving security is one of the best uses for this type of tool and perhaps the most relevant. To that end, we encourage reader comment, feedback and submission of material in the form of text, images and video, both on a public and private basis.

If you are a consumer, security professional, locksmith, business manager or even a kid and you have or need information regarding the insecurity of a product, system or service, we hope this will be the forum to ask questions or publish. We will highlight security vulnerabilities and present detailed information about the products and their manufacturers that you should rely on, and those you should not trust.

Those of you who are familiar with mechanical locks will recognize the term “sidebar” as denoting added security for pin tumbler cylinders. Sidebar is also a legal term that describes a side conversation about relevant issues. Either definition defines what this blog is all about. We believe that the public is better served by full disclosure of security issues that can directly affect personal safety and the protection of their assets, information or identities.

Security by obscurity (or perhaps more aptly described as security through ignorance) never works because criminals already know about your vulnerabilities and how to exploit them. We believe that knowledge is security. You require the knowledge to allow you or your organization to assess your own security risks and make the appropriate decisions regarding your selection of locks and security hardware.
