Bulldog Vaults BD1050

This handgun safe is a Chinese-made product featuring a locking mechanism called the ED Lock, made by Ningbo Lifang Metal Products Co., Ltd. The locking mechanism includes circuitry, controls, motorized boltwork assembly, bypass lock, and keypad fitting. Unfortunately, an oversight in the design if the keypad leaves the mechanism vulnerable to attack.


This safe was examined on October 2, 2015. Note: Since my original examination of the BD1050, Bulldog Vaults has had the keypad circuitry updated, which I confirmed by examining an updated safe.


Bulldog Vaults BD1150

This is a generic box marketed as a “car safe” by Jiangsu Shuaima Security Technology Co., Ltd., and Wujiang City Shenta Hengfeng Hardware & Plastic Products Factory. The device is simply a metal container made of thin steel and secured with a common wafer lock found on Chinese-made lock boxes and portable cases. Given how many times this lock has been exposed online, by me and by other security hackers, I’m surprised any importer is still willing to sell products with this lock installed on them.

Bulldog Vaults BD3000


The biometric-controlled locking mechanism installed on this safe is made by Ningbo Shuangjiu Safe Co., Ltd. The company makes multiple versions of this locking mechanism, including the Fingerprint Lock (SJZ8007-1M) and (SJZ8007-1J). Several Chinese manufacturers install this biometric device on their safes. Rayoo Security Co., Ltd., which manufactures the Biometric Fingerprint Safe Box for Laptops (FIN-SA200R) uses this locking mechanism, as does Ningbo Lifang Metal Products Co., Ltd.

Bulldog Vaults BD4010


This is another generic, Chinese-made safe. The safe is an excellent example of what can happen when recycled design components are thrown together without any consideration given to security. The keypad fitting on the door of this safe allows direct access to a hole in the safe’s door that in turn allows access to the main circuitry of the device. Everything from the design of the keypad fitting to the layout of the main circuitry board conspires to leave the electronics of this safe exposed.

Bulldog Vaults BD4020


The BD4020 is the next size up from the BD 4010. As with the smaller safe, this device is an example of what happens when recycled design components are thrown together haphazardly. Though Chinese manufacturers appear to know something about manufacturing safes, judging by the size of their product lines, their products are not engineered. Any given Chinese-made safe is a collection of recycled design components, accumulated in the process of manufacturing products for U.S. companies and others.

Bulldog Vaults BD4030

This is one of Bulldog Vaults’ Magnum RFID/LED Quick Vaults. The device comes packaged with an RFID card and key fob, giving the user a couple of different ways to activate the RFID sensor. Unfortunately, the device also has a familiar design vulnerability I’ve found in other safes—namely, a large gap around the bypass cylinder on top of the safe. The gap allows one to insert a shim into the interior of the locking mechanism.

Bulldog Vaults BD4050

This portable case is a generic import made by Rayoo Security Co., Ltd., based in Zhejiang, China. It’s the model GUN-HD58. The case is not California DOJ approved. Nor does Bulldog Cases & Vaults market it as being TSA complaint. I included the case among the other devices I examined for the simple reason that Bulldog Cases & Vaults markets the case as being appropriate for storing a firearm. The box it comes packaged in shows a snub-nosed revolver sitting inside it.


This safe was examined on November 25, 2015.


Bulldog Vaults BD4055

This portable case is an RFID version of a generic device made by Rayoo Security Co., Ltd. in China. After I compromised a biometric version of this device in 2017, Bulldog Vaults updated the latching mechanism in their portable cases. Yet, for whatever reason, the bypass cylinder was downgraded from a tubular lock to a simple wafer lock like the one I compromised back in 2015 on an earlier version of this device.


This safe was examined on January 18, 2019.


Bulldog Vaults BD4055B

This portable case is a biometric version of a generic device made by Rayoo Security Co., Ltd. in China. Unfortunately for the importer, Bulldog Cases & Vaults, this device is a perfect example of how a simple mechanical oversight can undermine the security of a device. In this instance, the spring holding the latch in place is light enough that the case can be bumped open against the palm of one’s hand.
