The Schlage 35-015 is the OEM "Do Not Duplicate," unembossed key blank from the Schlage Key Systems Cylinders and Keys Catalog (doc 109487), sold in a pack of 50 blanks. Keyway must be specified at time of order. The blank ships in nickel silver material, consistent with the Schlage key blank standard across the 35-series catalog. The 35-015 is the unembossed format: "Do Not Duplicate" is stamped on one side of the bow, and the other side is left smooth with no additional text or markings. This distinguishes it from the embossed-both-sides format (35-002) and from the unembossed-both-sides format (35-131). The 35-015 is a key blank, not a cut key - it requires cutting to the specified bitting before use.
What Unembossed Means and Why It Matters
Embossed key blanks have text pressed (embossed) into both sides of the bow - typically the keyway designation, the Schlage brand marking, and "Do Not Duplicate" legends on each face. Unembossed blanks have a smooth bow on one or both sides, with no pressed markings beyond what is stamped.
The 35-015 has DND stamped on one side and a smooth, unembossed surface on the other. This format is specified in three common situations. First, custom key identification: facilities that attach adhesive key tags, numbered stickers, or custom labels to their key bows find the smooth unembossed surface accepts labeling materials more reliably than the raised and recessed surfaces of embossed bows. Second, key hierarchy management: large master key systems sometimes use unembossed blanks for specific key levels (grand master, master, sub-master, change key) to provide visual distinction between key tiers without requiring custom stamping. Third, institutional and corporate key programs: hospitals, universities, and government facilities with structured key issuance systems often prefer smooth-bow keys because their own key management tags carry all the identification information.
Schlage 35-015 Key Blank: The Do Not Duplicate Designation
The "Do Not Duplicate" stamping on the 35-015 is not a legal prohibition by itself, but it is the industry-standard signal to locksmiths and hardware store key cutting services that this key should not be duplicated without explicit authorization from the key system owner. Reputable locksmiths observe DND requests as a professional standard. The DND format is the first line of key control on any commercial facility key system that does not use restricted keyways.
For facilities that need both DND designation and a smooth labeling surface, the 35-015 provides both from a single part number. The DND side satisfies the key control communication requirement; the smooth side accepts whatever identification system the facility uses.
Schlage Key Systems: Where the 35-015 Fits in the Key Blank Family
The Schlage 35-series key blank catalog covers multiple formats for different applications. The 35-015 is one of several DND-designated blanks:
35-100 = Standard bow, embossed both sides, no DND restriction. The basic operating key blank for standard Schlage key systems with no duplication restriction.
35-002 = DND, embossed both sides. The DND operating key blank where full embossing on both bow faces is specified.
35-015 (this product) = DND one side, unembossed smooth bow on the other side. For DND key programs where a smooth labeling or identification surface is required.
35-131 = Unembossed both sides, no DND stamping. Used when the facility key management system provides all identification externally.
35-003 = Control key blank, DND, embossed. For FSIC (Full Size Interchangeable Core) control functions.
Schlage Replacement Key Blank: Keyway and Pack Format
The 35-015 is available across the full Schlage Classic and Everest keyway range. Specify the keyway that matches the installed cylindrical lock cylinders on the project. Mismatching keyways produces a blank that cannot enter the cylinder, regardless of bitting.
The 50-pack format reflects standard commercial key blank ordering. Facilities cutting keys for new construction, tenant turnover, or master key system implementation order in 50-packs to reduce per-blank cost and ensure enough stock is on hand for the full keying program. Individual blanks are available at higher per-unit cost when smaller quantities are needed.
