Installation Notes

Key blanks must be cut using an appropriate key duplicating machine matched to the LD1 keyway profile. Confirm the keyway designation on the existing lock cylinder before cutting to avoid wasted blanks. This work is typically performed by a licensed locksmith or qualified door hardware technician. Always test the cut key in the lock before returning hardware to service.
