The BSC PREFERRED IAP99990919 is a nickel-plated brass key blank cut to the M1 keyway, designed for use with Master padlocks. Each bag contains 10 key blanks ready for cutting to code or by hand on standard key duplicating equipment. The brass construction provides corrosion resistance and the durability needed for repeated use in field and shop environments. Locksmiths, facilities maintenance technicians, and property managers typically stock these blanks to service Master-keyed padlock installations across job sites, storage areas, and utility enclosures.
This key blank is suited for residential and light commercial applications where Master padlocks keyed to the M1 keyway are in service. Facilities professionals, maintenance crews, and locksmith shops keep these on hand for high-volume key cutting operations. The 10-count pack format makes it practical for stocking service vehicles or supply rooms that routinely handle padlock rekeying and key duplication requests.
Designed as a replacement key blank for Master padlocks using the M1 keyway. Confirm keyway match against the existing key or lock cylinder before cutting.
Key blanks should be cut by a qualified locksmith or trained technician using calibrated key duplicating equipment. Verify the keyway profile against the original key before cutting to avoid material waste. Do not force an improperly cut key into a lock cylinder, as this can damage the cylinder pins. Follow any applicable facility access-control procedures when duplicating keys for secured areas.
