Schlage 35-002 Key Blank, "Do Not Duplicate", Embossed

The Schlage 35-002 blank is cut for a specific keyway, and you pick it when you order: C100, C120, C123, C124, C135, or C145. The keyway has to match the cylinder the key runs in, so pull the section stamped on an existing key or on the cylinder plug before choosing. A C145 blank will not enter a C123 cylinder.

Six pins. The 35-002 is cut on a 6-pin blade, so it suits 6-pin Schlage cylinders. If your building runs 5-pin cylinders, a 6-pin blank in the matching keyway can still be cut to a 5-pin bitting, but the reverse is not true, so check what depth your locks are pinned to before you buy a stack.

No. The "Do Not Duplicate" text is embossed into the bow of the 35-002 blank as a visible warning, not a mechanical or legal restriction. Any shop with the matching C-section blank can still cut a copy. If you need duplication genuinely controlled, you want a patented restricted keyway with key control on file, not a DND stamp. What the embossing does buy you is deterrence at the counter, which is why property managers use it on tenant and common-area keys.

Yes. Keying is a required choice on the 35-002: keyed different, keyed alike if you want a batch that all operate the same lock, or no keying if you want blanks only. There is also a key code field, so if you have the bitting code off your existing cylinder you can supply it and get keys that work with what is already in the door.

Order them keyed alike. Keyed alike is one of the keying options on the 35-002, which puts every key in the batch on the same bitting so one key runs the whole group. That is the usual setup for a property manager standardizing common areas or a maintenance key across a fleet of doors. Keep the keyway consistent across those cylinders too, since a key alike batch in C123 does nothing for a door running a C145 cylinder.

C123 is the everyday Schlage classic section and the one most standard Schlage cylinders ship on, so it is the safe pick if you are matching an existing building and nobody specified otherwise. C145 and the other restricted-side sections are used where a facility wanted keys separated from the common stock. The 35-002 is offered in C100, C120, C123, C124, C135, and C145, so confirm the section on a working key rather than assuming.

Commercial. The 35-002 is a commercial-grade blank, which is what you want for the Schlage cylinders in an office, school, or multi-family building. It works in residential Schlage cylinders too as long as the keyway section matches, but the DND embossing and the 6-pin blade are aimed at facilities where key control matters.

No. The 35-002 is non-handed. A key blank has no orientation, so left-hand and right-hand doors take the same part. The only fit variable is the keyway section and the pin count of the cylinder.
