Kwikset 81063-021 5-Pin, K Bow Cut Key, Cut To Bitting 23155

It arrives cut, not blank. The 81063-021 is a 5-pin K bow key already cut to bitting 23155, so it works straight out of the package on a cylinder keyed to that bitting. There is no cutting step and no trip to a key machine. If you want a key you can have cut to your own bitting, you want an uncut blank instead.

Only if that cylinder is keyed to bitting 23155. The key is cut to one specific bitting, so it operates locks pinned to 23155 and nothing else. Check the bitting stamped on your existing key or on the cylinder before you order. If your locks are on a different bitting, this key will enter but will not turn.

No. The Emtek MS4-KEYBLKC is a key blank cut for the Schlage C keyway, so it will not enter a Kwikset cylinder. The Kwikset 81063-021 is a 5-pin K bow key that comes already cut to bitting 23155. The two differ on both counts: keyway family and whether the key arrives cut or uncut. Match the keyway of the cylinder in the door first, then decide whether you need a finished key or a blank to originate.

Order the Emtek MS4-KEYBLKC, which is a key blank for the Schlage C keyway. The Kwikset 81063-021 is a 5-pin K bow key and belongs on Kwikset cylinders. Because the MS4-KEYBLKC is a blank, it needs to be cut to the bitting of the cylinder it will serve, whereas the 81063-021 arrives cut to bitting 23155.

Yes, provided the set is keyed to 23155. Ordering additional 81063-021 keys is the straightforward way to add copies for a property without pulling cylinders or rekeying, because every one comes cut to the same 5-pin bitting. Property managers handing out keys for a multi-unit building do this rather than duplicating at a hardware counter, where wear on the original gets copied along with the cuts.

A cut key such as the Kwikset 81063-021 ships already cut to a specific bitting, 23155, so it operates a cylinder keyed to that combination the moment it arrives. A blank such as the Emtek MS4-KEYBLKC ships with no cuts and has to be originated or duplicated on a key machine to the bitting of the cylinder it will serve. If you are handing keys to a tenant or a crew and already know the bitting, the cut key is the finished article; if you are keying cylinders yourself or duplicating in the shop, the blank is what feeds the machine.

The 81063-021 is cut with five cut positions, matching a five-pin Kwikset cylinder, which is the standard pin count on residential Kwikset locks. A cylinder with a different pin count will not read the cuts correctly. Since the key is pre-cut to bitting 23155, both the pin count and the bitting have to line up with your cylinder for it to turn.

The Kwikset 81063-021 is a residential 5-pin K bow key, which suits apartment and single-family cylinders and the smaller multi-family openings that use Kwikset cylinders. For a Schlage C keyed opening the Emtek MS4-KEYBLKC blank is the corresponding item, cut to the bitting of that cylinder. Where a facility is standardizing, decide the keyway across the doors first, since a key from one keyway family does not enter the other.
