    The 3210DC and 3230DC locks with the double sided keypad are excellent for use on gates to prevent un-wanted entry from either side. The locks install easy and are easy to set the code.

    I am an architect, and therefore try to plan ahead more that a lot of construction people. I have not yet built the gate and installed the hardware. I have looked at the products, and they appear to be everything I hoped for.

    I recently purchased my second keyless gate lock from GoKeyless. I had purchased the first one – a Lockey 3210DC, several years ago, and have found that I couldn’t do without it. It has performed flawlessly, and weather has had no effect. So I ordered another one for my second gate. Ordering online was easy and it shipped quickly. Thanks again for a great product and excellent service.

Customer Questions & Answers

  1. Answered by the admin

    Yes! This model does offer a Passage Mode function to keep the door unlocked until it is disabled again. 

  2. Answered by the admin

    This model is a deadbolt only as the bolt itself is the only mechanism on this unit that will secure your door. If you are looking for a lock with multiple locking points, please contact our sales staff at 937-247-9327, option 1!

  3. Answered by the admin

    This model does not feature any overrides for the deadbolt. However, these can be ordered with a mechanical key override! For more information, please contact us at 937-247-9327, option 1

  4. Q Can this lock be used with a vinyl fence? Gate border is 5" square. answer now

    Answered by the admin

    Yes, this model will work for vinyl, wood, or metal fencing. 

  5. Q Can this be used on a steel security storm door? answer now
    Asked by Deb Schoon on March 26, 2020 11:54 PM
    Answered by the admin

    It certainly can! Please keep in mind that this is a deadbolt and not a code entry handle. If you are looking for a similar double-sided handle set, please check out the Lockey 3835DC!

  6. Answered by the admin

    This is a purely mechanical lock and has no electronics to illuminate the keypad during the night hours. 

  7. Q Can each side have a different code? answer now
    Asked by Dan Whitaker on July 9, 2019 11:29 PM
    Answered by the admin

    Yes, each side has their own combination that can be set. 

  8. A

    It is a deadbolt so you will need to throw the deadbolt anytime you close the gate. If you would like something that locks behind you, you will need to go with a latching lock such as the 3230. 

  9. A

    No, these cannot use double digits and you can use any length from 3-6 digits. 

  10. A The gatebox that you would be looking for is the GB 2500. Please see the link below. https://www.gokeyless.com/product/kbxdig23-gate-box/
