Installation Notes

Key cutting and masterkey system work should be performed by a licensed locksmith or credentialed security technician. Verify the keyway profile and pin count against the existing system documentation before duplicating. Do not cut blanks on equipment not calibrated for the specific keyway profile, as improper cuts can damage cylinders or fail to operate the lock.
