Installation Notes

Key blanks must be cut on a properly calibrated key duplicating machine by a licensed locksmith or authorized key control administrator. Always verify the keyway designation and pin count match the target cylinder before cutting. Key cutting for restricted or controlled keyways may require proof of authorization under the facility key control policy. Do not attempt to cut this blank for cylinders outside the specified keyway family.
