Schlage 35-131 5-Pin Standard Key Blank G Keyway, Unembossed

The 35-131 is cut on Schlage's G keyway section, so it enters Schlage cylinders keyed to G and nothing else. It's a 5-pin blank, so it pairs with 5-pin cylinders. Because the bow is unembossed there's no keyway letter stamped on the blank to compare against, so read the section off the face of your existing cylinder or off the bow of the key you're duplicating before you buy a box of them.

Restricted sections take their own blanks. Everest cylinders use an undercut check pin that a conventional blade won't clear, and Primus adds a side bitting that a standard blank has no milling for. The 35-131 is a conventional G section 5-pin blank, so it's for standard Schlage G cylinders. If the key you're copying has a side groove milled into the blade or a notch along the top of the blade, you're looking at a restricted system and this isn't the blank.

It ships as an uncut blank. Someone with a duplicator or a code machine still has to cut it, either copied off a working key or cut to the bitting code for the cylinder. For a property manager stocking spares, that means buying blanks and having a locksmith or a shop with a key machine do the cutting; the blank itself carries no bitting.

Unembossed means the bow is plain: no Schlage stamping and no keyway letter on it. Two practical consequences. A locksmith or facility shop can stamp its own marking, tenant number, or DO NOT DUPLICATE on a clean bow. And once the key is cut, nothing on it tells you which section it is, so mark or tag them as you cut if you run more than one keyway in the building.

Keys aren't handed, and the 35-131 is non-handed, so there's no left- or right-hand version to specify and the same blank serves every door in the building. What has to match is the cylinder: every lock you want on one key has to be a 5-pin G keyway cylinder. Keying alike and masterkeying are done in the pinning of the cylinder, not in the blank, so ordering blanks is purely a question of matching section and pin count.

Commercial. It's the G section 5-pin blank used in commercial Schlage cylinders, which is what matters for a facility standardizing on a single key section across offices, storage, and tenant doors. Nothing about the blank restricts it to one door type, though, so if your residential units are also on G keyway 5-pin cylinders, the same blank duplicates those keys too.
