  3. Great product, Easy to use

    joey espinoza (verified owner)

    This is a solid option for people who want easy to use and install access options. I got the keycards with it and it’s simple to program, keeps a log of who uses what keycard etc. I like this option because it’s simply battery powered and doesn’t go down when power is out. The more expensive options require electricians and wiring etc but this was perfect for me.

Customer Questions & Answers

  1. Answered by the admin

    While this lock is weather-rated for outdoor use, it does not have an additional coating for added protection in marine/heavy salt environments. 

  2. Answered by the admin

    Yes! By default, this model will lock roughly 4 seconds after being unlocked by a valid credential.

  3. Q What is the battery life with typical use? answer now
    Asked by Maria on May 28, 2021 9:16 PM
    Answered by the admin

    The batteries in this model are noted to last up to two years. We typically recommend exchanging these batteries annually as the battery life does depend on usage and how often communication/programming is performed. 

  4. Answered by the admin

    The cards will only need to be enrolled once. Once the user exists on one lock, you can assign existing users to have access to other locks within your account on the K3 Connect app. 

  5. Answered by the admin

    The operating temperature of this lock is -40°F to 150°F. For cold environments such as this, we typically recommend a mechanical lock rather than an electronic one. 

  6. Answered by the admin

    Yes! The outside keypad is weather protected and can be used for exterior entry doors. 

  7. Q Can I use a tablet in place of a smartphone? answer now
    Asked by Ted on February 19, 2021 2:04 PM
    Answered by the admin

    You certainly may so long as the tablet is BLE enabled. 

  8. Answered by the admin

    They certainly can! To accomplish this, you would need the Codelocks Wi-Fi gateway to connect to the lock remotely. For more information, please contact our sales department through the online chat service or over the phone at 937-247-9327, option 1!

  9. Answered by the admin

    With this model, you are able to schedule certain periods through the day where codes/cards can be used for access. This can be done remotely through the K3 app if you are using the Wi-Fi bridge with this lock. 

  10. Answered by the admin

    This model does not feature a privacy button or knob on the interior side of the unit. For a lock model that does have this feature, we would recommend reaching out to our sales department at 937-247-9327, option 1 for options that will work best for your application.
