Detailed Report on The Insecurity of Gun Safes Made By Leading U.S. Manufacturers: Stack-On, Gunvault, and Bulldog

All of these gun safes can be easily opened with a variety of simple tools.

See my corresponding article in Forbes that was published on Friday, July 27, 2012.

See the applicable disclaimers with regard to the information contained in this report at the end of the Alert.

This security alert provides detailed information about small gun safes that can be easily compromised. We conducted an analysis in our Security Lab of these containers. Some of these containers are utilized by law enforcement agencies. A PowerPoint presentation and video is available through the AFTE website for any agency, and was the subject of my presentation at the Annual Association of Firearms and Tool Marks Examiners conference in Buffalo, New York on June 28, 2012.

We provide information about some of the most popular gun safes that are produced by the leading manufacturers in the United States: Stack-On, GunVault, and Bulldog. We also looked at one of the small safes produced by AMSEC.

We tested safes from these companies to determine their vulnerability to simple, covert attacks. We did not test for forced entry techniques.
Every consumer that owns or is contemplating owning a small gun safe needs to understand that many of these containers are improperly designed, have little real security, and can often be opened in seconds with common implements such as paper clips, drinking straws, wires, and small pieces of brass. Some can also be dropped from a few inches onto a hard surface and opened because of the simple, cheap, and insecure mechanism that is used to block movement of the bolt work until the proper combination is entered.

All of these safes utilize electronic credentials to open them. While these manufacturers would like you to believe that the use of a keypad, push-button sequences, or fingerprint reader will somehow make their containers more secure, it is not accurate and everyone should understand it. It is merely for convenience.

What constitutes security in any container is the way the locking mechanism is designed to keep the container closed or to be opened. The problem is that none of these manufacturers seem to understand even the basics of security engineering and how to defeat their own products. In this report, we will provide detailed videos that demonstrate the problem for many safes that are sold by Walmart, Cabelas, Dicks Sporting Goods, Scheels,

In conjunction with our investigation we contacted and made available these videos to management at all of these companies. Only Walmart would even issue a statement, which essentially says “it is not our problem” and we rely upon the manufacturer and the California DOJ standards.

The other companies, Cabelas, Scheels, and Dicks Sporting Goods had absolutely no response.

All of these companies continue to sell what we are claiming are dangerously security-defective products, but it evidently is all about money, not the safety and security of their customers that is of their primary concern. They have all been placed on notice of the defective security designs and all have chosen to ignore the evidence and instead rely upon what the manufacturer, Stack-On or others have represented to them.

Stack-On is headquartered in Illinois and by their own account, generate about $100,000,000 annually. They also indicated that they do not talk to the media, but they did issue a press release after I demonstrated opening four of their safes on KELO-TV in May, 2012.
Their Public Relations firm issued the following statement on behalf of their client:

“While Stack-On respects Mr. Tobias's proven ability to pick the most complex of security locks, we strongly stand behind the safety of our products. Stack-On Personal Safes are certified by California Department of Justice (DOJ). This certification involves testing, by an independent laboratory approved by California DOJ, for compliance with adopted standards. We are proud of this designation and the protection we provide. In addition, our Portable Cases comply with TSA airline firearm guidelines.”

Stack-On believes that their safes are secure. While their containers have been approved by California DOJ under their gun safety regulations, they are fully aware that the methods we demonstrated are not addressed in these standards, and thus the standards are not applicable. It is our opinion that Stack-On has chosen to continue to place every buyer of one of these safes at potential risk. Their safes are manufactured in China. While they may appear to be secure, they are not, as we demonstrate in multiple videos.

I spoke with their VP of Marketing, Steve Martin, in April, 2012. I asked to do an interview at their facility and was refused. When I advised him that we had tested several of their safes, he did not ask one question. I offered to send the links of the videos. He offered no response. The company has never followed-up with any inquiry.

Our opinion is that Stack-On should recall every safe that has security vulnerabilities and issue an alert to the public to warn every purchaser. They should also warn every vendor. To our knowledge, they have done neither. What they have done is to continue to sell what we allege are defective products to the public, knowing that many of these containers can be opened by kids.

I spoke with a spokesperson for Walmart and provided links to all videos. After two months, they finally issued the following statement:

“Walmart is committed to providing safe, quality products customers can rely on. After being made aware of your concerns, we reached out to the manufacturer of Stack-On products to discuss their compliance and quality programs. According to Stack-On, the product you mentioned is tested by a third party independent lab and those results are submitted to the California Department of Justice for certification as meeting their safety standards for this category of products.”

It is also our opinion that Walmart is far more concerned about revenue than in protecting the safety and security of their customers, notwithstanding their claims to the contrary. According to their employees, the company has a security and safety testing team that analyzes products. That would indicated that they have the competence and skill to evaluate the claims that we made.

Walmart did not deny our allegations but rather are avoiding responsibility by hiding behind the representations of Stack-On. In our opinion, nobody should believe anything that Stack-On states with regard to the security of any of their products. It is very clear that Stack-On has no competence to design or test a container for security vulnerabilities.

While they may believe that they can avoid liability by claiming they meet the requirements of the California gun statutes, they may find that those standards offer no protection whatsoever. We believe they are producing dangerously defective containers that they are representing as secure for use by the consumer to store weapons. They are not secure, and nobody should rely upon them for any measure of security.

It is my opinion that any retailer, once on notice of the defects we have demonstrated, can and will be held liable if a customer purchases one of these containers and the result is that someone is hurt or killed.

We conducted undercover interviews at Cabelas and Scheels to document what their sales “experts” were telling the public about these safes. It is precisely what you would expect: they are secure, kids cannot get into them, and you can safely store weapons in them without fear that they can be covertly compromised.

Unfortunately, each of these statements is false. The problem is that these sales personnel do not have a clue as to what is secure or is not. What they understand is profits and what sells, and it would appear that is all they care about, based upon the total lack of response from any of these companies to us.

While we only looked at about ten safes, we are quite sure there are dozens, if not hundreds of different models that are similarly insecure. Most of this junk is made in China and peddled by U.S companies. These safes are cheaply made, and the security engineering is essentially non-existent, as you will see in the videos and our detailed analysis.


This is a common solenoid design that blocks the movement of the bolt in many safes. The magnetic pin must retract in order for the bolts to pass. This can be vibrated to an unlocked state.

As a result of another gun death involving a member of the Clark County Sheriff’s Department in 2003, the Sheriff mandated that all deputies keep their weapons in designated Department safes at their homes. The Department, without any testing, initially purchased approximately 200 Stack-On Strong Boxes, shown in the video. It is clear that the CCSO relied upon the representations of Stack-On, and had no independent expertise to evaluate the security of these containers. It is incredible to us that the Department would entrust the lives of their officers and families to a container that reportedly cost $36.00 without any tests being conducted by the Department as to suitability, safety, or security.

Detective Ed Owens was a member of the Clark County Sheriff’s Department since 2004. He was issued a Stack-On safe to store his weapons at home. On September 14, 2010 one of his four children was able to open the Stack-On Strong Box container that was located in the Master Bedroom. At about 9:50 P.M. three-year-old Ryan was shot and died four hours later.

We were asked by the Owens family and attorney to provide expert analysis of the suspect safe. We conducted an extensive analysis of a container from the same batch that was provided to the Clark County Sheriff’s Office.

It is our opinion that these were defective containers, based upon the testing we performed and the videos we shot from inside the safe. The problem, quite simply, revolves around the solenoid mechanism that controls a locking pin. This pin when in its normal state blocks lateral movement of the bolts thereby preventing their retraction. When the correct code is entered, via the keypad, the blocking pin is retracted and the bolt can be turned to the unlocked position. The problem is the design of the solenoid and spring-biased locking pin. It can be bounced to allow the bolts to pass and leave the safe in an unlocked state. As demonstrated by the three-year-old in our video, this safe can then be opened by simply turning the knob.

As a result of testing this particular safe, we expanded our inquiry and tested virtually every Stack-On model of small safe. What we found was disturbing. Each could be opened in a variety of ways, as we demonstrate. We also tested similar containers from Bulldog and GunVault. We reached out to these companies as well, but they refused to return phone calls.

Any consumer that owns one of these containers should return it and ask for a model that has been fixed to made it secure, or demand a refund. In our view, no weapons or valuables should be stored in one of these containers.

We provide all of the video segments of our analysis as well as televised news reports and some of the undercover video that we obtained.

We tested safes produced by Stack-On, Bulldog, Amsec, and GunVault between February, 2012 and July, 2012. We tested a limited sample of each and produced videos of unaltered containers. A manufacturer may have updated or made changes to a design that would make more difficult or prevent us from opening that container in the method shown. The reader or consumer should replicate the methods shown for any particular container and run their own tests. We have no financial interest in any of the manufacturers that are detailed in this report. See the other disclaimers contained on this website.
