Customer Questions & Answers

  1. Answered by the admin

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

  2. 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. 

  4. 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.

    The model shown here is a single-sided keypad. If you need a doublesided model that requires a code to enter or exit, please see the back-to-back version here:

    This model would not be recommended for your application. For better options, please contact our sales staff at 937-247-9327, option 1 or [email protected]

    The Simplex 1011 can be ordered with levers instead of knobs (L1011)! However, the double-sided model can only be ordered with knobs. The manufacturer does not offer a back-to-back model with lever handles. For more options of locks that do offer double-sided lever entry, please feel free to contact our sales staff at 937-247-9327, option 1 or by email at [email protected]!
