Schlage SC1-UN-DD SC1 Do Not Duplicate Key Blank

Product Description

The SCHLAGE SC1-UN-DD is a single key blank cut to the SC1 keyway profile and stamped with a Do Not Duplicate (DND) marking. Key blanks in this category serve as the starting material before a key is cut to a specific bitting pattern. The SC1 keyway is one of the most widely used residential and light commercial keyways in the Schlage product line. Locksmiths, property managers, and security-conscious facilities staff specify DND-marked blanks when key control is a priority. This blank is sold as a single unit and is intended for professional key-cutting equipment.

The SC1-UN-DD fits lock cylinders that accept the SC1 keyway, which appears throughout residential entry locksets, deadbolts, and light commercial cylindrical locks. The DND marking communicates to key duplicators that unauthorized copying is restricted. This makes it appropriate for controlled-access applications in apartment complexes, small offices, and institutional settings where tracking key distribution matters. Locksmiths and facilities maintenance personnel are the primary installers and users of this blank.

Compatibility

Designed for use with lock cylinders that accept the SC1 keyway profile. Specific compatible lock models were not provided in the product data; consult cylinder documentation to confirm keyway fitment before cutting.

Installation Notes

Key blanks are cut by a qualified locksmith or trained facilities technician using a code-cutting or duplicating machine. No electrical shutoff is required, but the lock cylinder should be removed from service and inspected before new keys are issued. Always verify the keyway profile against the target cylinder before cutting to avoid wasted blanks or damaged equipment.
