Strength of Security

Here are some of the features that make this such a robust door lock.

• Mainly constructed of metal in both interior and exterior units for strength of security. Keypad cover, battery compartment, and open/close buttons are all made of metal for added security. 
• Three main components are designed to withstand hammering. The Tag Key sensor, temporary power terminal, and the keypad are supported by metal or hard rubber parts so that any impact on them is born by a 2.5-mm thick metal mounting plate as well as the door surface, thus protecting the circuitry in the exterior unit. Smashing any of these components will not automatically yield access to the intruder.
• The exterior mounting plate block intruder access to the deadbolt latch if the exterior unit is broken off. This prevents intruders from gaining access to your home, even if your lock is broken or damaged.
  
• The 1-inch throwbolt is strengthened with a 5 mm. thick carbon rod that completely resists sawing.
  
• The opening between the exterior and interior unit is small and covered to that hot and cold air cannot penetrate your home, minimizing condensation and rust.
  
• Built-in weep holes help moisture from the exterior unit flow down and out of the unit. The weep holes are partially blocked by the mounting plate to prevent break-ins.
• The battery compartment cover is fastened with a screw to prevent batteries falling out. With added rubber pads, this will secure the batteries in place.
  
• Manual override directly operates the deadbolt latch so you will always be able to open the door from the inside. 
• The vital parts of the lock such as the CPU, PCB, batteries, motor, deadbolt latch drive mechanism, etc., are located in the interior unit on the secure side of the door and are further protected by a heavy-duty interior mounting plate that disallows any access to the vital parts.
• A bypass circuitry that protects the PCB in case of a high-voltage attack so that the lock remains locked.

Quality

The Digital Deadbolt Lock was developed by engineers who have been at the cutting edge of keyless technology since its advent in the 1990s. Millions of digital door locks have been used in government, corporate, and home applications throughout the world including South Korea, Japan, England, USA, and even Kazakhstan. What makes The Digital Deadbolt Lock special is that it is a culmination of all of the knowledge and experience gained from making digital door locks for almost a decade and that it is made specifically for the American residential doors.

What makes The Digital Deadbolt Lock different is the manufacturer's vigorous standards of quality. All of the separate parts are sampled frequently and tested for strength and security before they are entered into the manufacturing process. The suppliers of parts and materials must adhere to strict standards of quality and their performances are measured against an ever-improving benchmark.

Once inspected, the parts are stored in a climate-controlled storage room. The PCBs are manufactured by state-of-the-art lead-free soldering machines that solder computer chips onto the board. As each unit is assembled, it is tested at each step of the assembly line making sure that a defective unit, if any, is detected immediately.

Lastly, our manufacturing facilities, with a monthly production capacity of 100,000 units, are certified for ISO 9001 (Quality Management) and ISO 14001 (Environmental Management System.
