Installation Notes

Key cutting and duplication should be performed by a licensed locksmith or qualified security hardware technician using appropriate key cutting equipment. Verify the keyway profile and pin count match the target cylinder before cutting to avoid creating a non-functional key. Restricted keyway blanks may require authorization documentation depending on the facility's key control policy. Always follow the facility's masterkey system protocol when originating new keys within an existing access hierarchy.
