It might come as no surprise that, much like recent stories about backdoors into encryption systems and poorly implemented DIY security, electronic locks have similar problems [wired.com] (originally seen on Bruce Schneier's Blog [schneier.com]).
Rowley and Omo’s research began with that same concern, that a largely undisclosed unlocking method in safes might represent a broader security risk. They initially went searching for the mechanism behind the Liberty Safe backdoor that had caused a backlash against the company in 2023, and found a relatively straightforward answer: Liberty Safe keeps a reset code for every safe and, in some cases, makes it available to US law enforcement.
Liberty Safe has since written on its website that it now requires a subpoena, a court order, or other compulsory legal process to hand over that master code, and will also delete its copy of the code at a safe owner’s request.
Rowley and Omo didn't find any security flaw that would allow them to abuse that particular law-enforcement-friendly backdoor. When they started examining the Securam ProLogic lock, however, their research on the higher-end version of the two kinds of Securam lock used on Liberty Safe products revealed something more intriguing. The locks have a reset method documented in their manual, intended in theory for use by locksmiths helping safe owners who have forgotten their unlock code.
