  1. Good Coded Door Lock

    JS Visser Produce

    We have several on all our warehouses. Most work great and easy to use. We have had to replace a couple within a year due to door handle issues but did replace with same as we can’t find any other that are as heavy duty or work as well.

  4. Q Does this work on a chain link gate? answer now
    Asked by Bob jessop on August 17, 2022 5:05 PM

    You can install this on a chain link gate but it would need mounted on a gatebox. This box is pre-cut to work with this lock

    1. Remove the inside knob by using the
    pointed end of the spanner wrench (item “i”
    on the checklist) to depress the spring
    loaded retaining clip, visible through the
    poke hole in the collar of the cylindrical
    drive unit.
    2. Pull the knob while simultaneously
    releasing the retaining clip.
    3. Remove the knob from the lock body

  7. Answered by the admin

    For this feature, you will need the Simplex 1031 model!

  8. Answered by the admin

    Since no combination will unlock the door currently, the combination chamber will need to be manually reset. This process will require the lock to be removed from the door. 

    To reset the combination chamber without the current code, please follow the steps in the document below.

    These locks can certainly be installed on a gate but may require a gate box for proper mounting. The Simplex 1011 does not offer an override but the Simplex 1021 does feature a manual key override to bypass the keypad if desired. 

  10. Answered by the admin

    Unfortunately, the lever and knob models each require slightly different housing. The lock will need to be ordered for either knob or lever usage.
