Installation Notes

Installation of this driver should be performed by a qualified commercial locksmith or licensed door hardware technician. Before servicing, ensure the lockset is removed from the door or that the latch mechanism is fully disengaged and the door is secured in an open position. Follow the ND Series disassembly procedure to access the core driver housing. Do not force the component into position, as improper seating can affect core retention and lock function.
