The Schlage 35-268 is the OEM Everest 29 key blank with "Do Not Duplicate" embossed on the bow, packaged with 50 blanks per box. These are full-size, 6-pin conventional key blanks for Schlage commercial lock systems using the Everest 29 keyway family. They're what a commercial locksmith or facility key shop cuts against to produce working change keys for any Schlage cylindrical or mortise lock that runs on Everest 29 cylinders — which covers virtually every Schlage commercial lock produced under the current keyway standard.

Keyway must be specified at time of order. Available keyways on this page include S123, S124, S125, S135, S145, S234, S235, S245, S345, T000, T100, T120, T123, T124, T125, T134, T135, T145, T150, T230, T234, and T345.

Schlage Everest 29 Key Blank System: S and T Keyways Explained

The Everest 29 keyway family is Schlage's current commercial key standard, replacing the legacy Classic keyway family. It includes S and T keyway families for conventional and FSIC cylinders, and the R keyway family for SL-format cylinders. The 35-268 covers the S and T family blanks.

S keyways are open keyways. S123 is the default keyway on all new Schlage commercial locks as shipped from the factory. S145 is the default keyway for Schlage master key systems. S keyways have controlled distribution — available through Schlage commercial channels only, not at retail key counters or home centers — but they don't carry the same geographic restriction as T keyways. Facilities that need fast key duplication through authorized commercial locksmiths typically run S keyways.

T keyways are restricted keyways with tighter distribution controls than S keyways. T family blanks are available only to Schlage commercial end-user customers and approved commercial dealers. The numeric designation in each keyway (T123, T145, T234, etc.) corresponds to the sections of a masterkey system hierarchy, helping key system designers build large multi-level key systems with clear separation between different user groups, floors, buildings, or departments.

Both S and T keyways use 6-pin conventional cylinders with a check pin. The check pin is Everest 29's signature security feature — the key must lift this check pin precisely to allow the cylinder to rotate. An incorrect key or a generic blank cut to the wrong keyway profile won't lift the check pin and won't turn.

Schlage Key Blank Chart: Understanding the 35-268 Part Number

In the Schlage key systems catalog, the 35 prefix designates key blanks (uncut). The 268 designates the full-size Everest 29 bow with Do Not Duplicate embossing. The 35-270 is the same blank without DND embossing, and the 35-269 is the control key blank for interchangeable core applications. For cut keys, the prefix changes: 48 for change keys and 49 for master keys.

The DND embossing on the 35-268 is raised text on the key bow instructing key shop personnel not to make copies without authorization. It's a deterrent, not a legal lock. The true key control on Everest 29 comes from patented blank distribution: Everest 29 blanks are available only through Schlage's commercial channel, and the Everest 29 through-cut design (protected under U.S. Patent Nos. 5,809,816 and 5,715,717) makes unauthorized duplication an offense under federal patent law

The key bow is the larger, rounded full-size design specific to Everest 29, creating quick visual differentiation from legacy Everest blanks. The through-cut technology increases key blade thickness by approximately 20% compared to the original Everest for improved shear strength.

Schlage blank keys are packed 50 per box (this listing) and 1,000 per case for high-volume key shops.
