  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

    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. 

  2. Answered by the admin

    This lock can be preprogrammed at the unit or through the K3 application prior to installation. We would recommend keeping power applied for as long as possible and try to avoid pressing any buttons on the front keypad while the batteries are disconnected. 

  3. Q Can this be installed by a Do-it-yourself? answer now

    This model is quite easy to install in place of an existing handle. Typically, the lock can be installed with just a Phillips head screwdriver. A drill may be needed to make adjustments to the mounting as needed,

    This system does have the capability to send out notifications when the door is unlocked by a valid credential.

    The lock does include a key override and the handing is reversible! The lock will certainly work for both left and right-handed doors.

    Wi-Fi is only needed for remote control/programming. The programming can also be accomplished manually at the keypad or from your smartphone via Bluetooth connection. No Wi-Fi connection is needed to operate the lock.
