Customer Questions & Answers

  1. Q Is this battery operated? answer now
    Asked by Megan on May 25, 2022 2:05 PM

    This model is fully mechanical and does not require batteries. 

  2. A

    It's projects from the door about 2 1/4 inches. 

  3. A

    This lock can certainly be used for this application. Alternatively, you can order a double-sided model if you require a keypad on both sides of the door. 

  4. A

    This model will do the trick! The interior knob is a passage knob that will always allow free egress. The exterior portion will require a code for entry but can be placed into a passage mode if you wish to allow free entry for a short time. 

  5. A

    The numbers in the access code can be entered in any order to gain access. 

  6. A

    Replacement parts are available for this model through our sales staff at 937-247-9327, option 1!

  7. A

    The latches on this model have a 1-inch throw. These can be used on gates thicker than 2" if used with the Lockey Extension kit

  8. Q Is there a way to program a secondary code for deliveries? answer now
    Asked by Marina on March 2, 2021 3:44 PM

    These locks are mechanical and can only be set to a single combination at a time. 

  9. A

    Yes, the lock will need to be removed from the door to change the access code for this model as you need to access the back panel.
