Customer Questions & Answers

  1. Q Is there a cylinder available for a master 6 pin? answer now
    Asked by Eugene on January 13, 2021 2:57 PM

    This model is designed to accept 5 or 6 pin SFIC cores. These cores can be master keyed if requested but will typically ship with a control key (to add or remove the cylinder) and an operator key (to unlock the device).
