What others are saying

  1. It does the job but not 100 % satisfied with it

    Geri A. (verified owner)

    I like the look of the product. It does have a few flaws. We use this door knob at an office.
    It does not like to connect with the app on my phone very easily. I practically have to be standing next to it to get it to connect in a timely manner. It does not offer a way to manually lock the door from the inside. I feel that it uses way too much battery life. I’ve changed the batteries 2 times since installation about 5 weeks ago. We knew a bridge would have to be bought to make this work remotely. While we had no plans to purchase one, we did after the fact for remote management.

  2. Unreliable and not good for AirBNB/STR


    Don’t be fooled into buying this if you are trying to do remote management for short term rentals.

    I have two rooms with these locks. You must purchase add’l equipment (bridge) to use remotely via wi-fi.

    1) Connecting remotely is very unreliable.

    2) Temporary users can only be setup with real emails (not virtual emails like guest Airbnb emails) and there is no ability to setup temporary users with a unlock code number. This makes it impossible to automatically delete guests access at checkout time.

    So, for short term rentals, a major pain in the neck to log in remotely (and hopefully connect, cross your fingers) to add users with a code and then you must log in again to manually delete each user when they checkout because you can’t schedule the code to expire.

    I will replace at my first opportunity.

  4. A great lock, a great price.

    Shelly Davis (verified owner)

    We started with 1 on the most used door. The fingerprint feature works great for me, but some of our employees (>75) have trouble with the finger print option. Granted they work in temperatures up to 115 degrees at the marina, so cleanliness is not priority when heading home. We have expanded to 3 more doors. The ease of adding deleting employees is important in our seasonal environment It cuts down on lost keys. The I pad app is easy to use, w/a log of use, and a unlock feature. Good Battery Life.

  6. Not ready for prime time

    Dave Hart

    Looks great, easy to install. Not reliable, prone to fail. I have 5 of these and have replaced 4 of them, at least once, in the first 6 months. Bluetooth does not work well and it takes several days to get a replacement. Not a good choice if you need reliable access control. One replacement was clearly a used unit, the others appeared new.

Customer Questions & Answers

  1. A

    No, this has basic programming. Anything more indepth you would need a commercial lock with software and programming such as a DL2800.

  2. A

    Salt air is going to be difficult for any lock but these have additional fingerprint readers that cannot handle that type of exposure. It is not recommended for direct contact with salt water as it will hurt the fingerprint sensor. 

  3. A

    You must be within Bluetooth range in order to interface with the lock. It does not have a remote capability. 

  4. A

    The lock is rated for -70C for the exterior portion and up to 55C on the interior portion of the lock. We always recommend that a weather guard is used in such extreme conditions as it does help improve the life of the lock and to keep the fingerprint reader clear of any snow and ice. 

  5. A In order for us to know if this will work with your keyway and latch, we will need to know what type of keyway and style of latch you have (cylindrical versus tubular). In a situation such as yours, it is suggested to speak to our professional door specialist to ensure your configuration will work. Please call them at 937-247-9327 option 1

    It would depend on if you can download and properly use the appropriate user app for the lock. Many apps are designed for phone only use so it would depend on first if the app is available on iTunes and second if it will work with a MacBook. The only way to find out would be for you to download it onto your MacBook to see if it will operate if it is even available to do so from iTunes. 

  7. A The keypad is a backlit keypad for low light and dark areas. As for the weather rating, this lock is not recommended for an exterior door. Because of the biometric reader on the exterior side, the lock is not rated to withstand wet or damp conditions.
  8. A With the Ultraloq app you are able to view the log history of users that you have setup and created in the lock. This log will give you time and date stamping of the user that you are looking at.
  9. A

    Unfortunately, not without taking the lock apart and that would void the warranty. 

  10. A
    Yes, you can enable and disable a passage mode anytime you have a meeting.
