Kwikset 81063-009-5 Pin Extra Random Cut Keys

These Kwikset 81063 extra keys come cut to a random bitting, not blank. That matters: they are not cut to match a lock you already own. They arrive as a set of keys sharing one random cut, so they go with a cylinder that gets pinned or keyed to them, or they serve as the keys for a lock being set up fresh. If you want copies of a key you already carry, a locksmith duplicating from your existing key is the route, not a random cut set.

Not as they come. The 81063 keys are cut to a random bitting of their own, so they will not turn an existing cylinder unless that cylinder is re-pinned to match them. On a Kwikset residential cylinder a locksmith can pin to the key you hand them, which is the normal way these get used. If the goal is to have every door in a house open with one key, key the cylinders to a single one of these keys rather than expecting them to fit what is already in the door.

Kwikset and Schlage keyways are not interchangeable, so the 81063 keys will not enter a Schlage cylinder at all. For a Schlage C keyway, the Emtek MS4-KEYBLKC key blank is the part to look at. Note the difference in what you get: that Emtek part is a blank, so it needs cutting to your bitting, while the Kwikset 81063 arrives already cut to a random bitting.

They are at opposite ends of the key-cutting process. The Kwikset 81063-009-5 is a set of 5-pin extra keys supplied already cut to a random cut, so they arrive ready to key a cylinder to that bitting with no machine work. The Emtek MS4-KEYBLKC is a key blank on the Schlage C keyway, which means it ships uncut and has to be cut on a key machine to whatever bitting the cylinder uses. Choose the Kwikset 81063-009-5 when you want finished keys in hand, and the Emtek blank when you are cutting keys yourself to an existing bitting.

Not as a drop-in. The Emtek MS4-KEYBLKC is a Schlage C keyway blank, so its blade profile is made to enter Schlage C cylinders and it will not enter a Kwikset cylinder regardless of how it is cut. It also arrives uncut. The Kwikset 81063-009-5 is a Kwikset 5-pin extra key supplied pre-cut. If the hardware is Kwikset, stay with the Kwikset 81063-009-5; the Emtek blank is the choice only when the cylinder takes a Schlage C key.

Five pin refers to the number of pin chambers the key is cut for, so these suit a five pin Kwikset cylinder. That is the standard chamber count on Kwikset residential locks, which is what the 81063 keys are catalogued for. A six pin cylinder takes a key cut across six positions and is a different animal, so match the chamber count of the cylinder you are keying before you order.

They are catalogued for residential use, and a random cut set is the wrong starting point for a master key system in any case. Master keying needs bittings assigned from a keying schedule so change keys and master keys sit in a controlled relationship, and a random cut cannot be dropped into that. For a house, a rental unit, or a small multi-family door where all you want is a working key for a rekeyed Kwikset cylinder, the 81063 set does that job.

That depends on the keyway of the lock you are matching. To duplicate a bitting you already have, you need a blank on the correct keyway and a key machine: the Emtek MS4-KEYBLKC is a Schlage C blank for cylinders that take a Schlage C key. The Kwikset 81063-009-5 is a set of 5-pin Kwikset keys that come cut to a random bitting, so they are used to key a Kwikset cylinder to a new bitting rather than to match a key you already carry. Duplicating an existing key means starting with the blank; setting a fresh bitting on a Kwikset cylinder means starting with the pre-cut 81063-009-5 keys.

The Kwikset 81063-009-5 5-pin extra cut keys are specified for residential use, which fits single-family doors, rental units, and multi-family apartment entries running Kwikset cylinders. The Emtek MS4-KEYBLKC is a Schlage C keyway blank, a different keyway family, so it belongs to openings built around Schlage C cylinders instead. For a property manager rekeying a block of units, the deciding factor is which keyway is already in the doors, not the grade of the key itself.
