Customer Questions & Answers

  1. Q How long before it will auto lock? Are there options for how long? answer now
    Asked by Samantha Larsen on April 4, 2024 10:25 PM
    Answered by the admin

    This lock is fully mechanical and will relock as soon as a valid code is entered and the handle/knob is rotated to gain access. When the lock is in a passage/unlocked state, the lock will need to be manually relocked. You are not able to set a timed automatic relock function on this model. 

  2. Answered by the admin

    If you need a single sided keypad that allows auto locking and free exit from the interior, the best option would be the Lockey 2830 or the Lockey 2835 if you desire a lever lock!

  3. Answered by the admin

    All Lockey mechanical locks are only able to have one code set at a time. 

  4. Q Would it work on a vinyl gate? answer now
    Asked by elaine on August 21, 2022 6:44 PM

    You could install this on a vinyl gate, yes. 

  5. Answered by the admin

    The Lockey GB2500 is the correct gate box for this lock model. 

  6. Q What is the difference between the 2830dc and the 3830 dc? answer now
    Asked by Shannon Livingston on December 29, 2020 4:26 PM
    Answered by the admin

    The 2830DC is considered a medium-duty model while the 3830DC is considered a heavier duty lock that is also available in marine-grade finishes for resistance to high salt/moisture environments. The functions of both models are identical. 

  7. Q What is the door prep? Link? answer now
    Asked by Laurie on November 8, 2020 2:54 PM
    Answered by the admin

    This model requires a standard 2 1/8 in. cross-bore and fits doors that are  1 3/8" to 2" thick. This lock comes with an adjustable backset for a door drilled for a 2 3/8" OR 2 3/4" backset.

  8. Q I have a wooden gate on the exterior fence. Would this lock work? answer now
