Kwikset 81210-002-6 Pin Extra Random Cut Keys

They come cut. The Kwikset 81210-002 is a 6-pin extra key supplied with a random cut, so it arrives with a bitting already on it rather than as an uncut blank. That means it does not match an existing lock unless you have the lock keyed to it, or you cut it down to your bitting.

No. This is a 6-pin key, cut for 6-pin Kwikset cylinders. A standard residential 5-pin Kwikset cylinder takes a 5-pin key, and the two are not interchangeable. Check the pin count on your cylinder before ordering.

They serve two different points in the process. The Kwikset 81210-002 is supplied as extra random cut keys, meaning the blade is already cut to a random bitting and the keys work as a set with each other out of the box. The Emtek MS4-KEYBLKC is a key blank on the Schlage C keyway, so it arrives uncut and has to be cut on a key machine to the bitting of the lock it will operate. Choose the Kwikset 81210-002 when you want finished 6 pin keys in hand; choose a blank when you have a cylinder already keyed and need copies made to match it.

No. The 81210-002 are Kwikset 6 pin cut keys and follow the Kwikset keyway profile, so the blade will not enter a Schlage C keyway regardless of the cut. For a Schlage C cylinder the matching stock is a Schlage C blank such as the Emtek MS4-KEYBLKC, which is made on that keyway and then cut to the cylinder. Keyway profile is the first thing to confirm before bitting, because a key cut to the correct depths on the wrong keyway still will not insert.

Not directly. Random cut means each key carries an arbitrary bitting, so it will not match keys you already have. The usual workflow is the reverse: pick one of these keys, then pin the 6-pin cylinder to that key so the lock follows the key. If you want doors keyed alike, all those cylinders have to be pinned to the same key.

The Kwikset 81210-002 arrives with a random cut on it, so it is not what you want for blank stock. For an uncut blank, the Emtek MS4-KEYBLKC Key Blank in the Schlage C keyway is an option if your cylinders are Schlage C. Match the blank to the keyway your cylinders actually use, since Kwikset and Schlage keyways are not interchangeable.

Not if the keys have to match a bitting that already exists. The 81210-002 keys come cut to a random bitting, so they suit a situation where the cylinder is being pinned to the keys or where a new independent key set is wanted for a unit. When the requirement is to duplicate an existing key, the stock to buy is an uncut blank on the correct keyway, such as the Emtek MS4-KEYBLKC for Schlage C cylinders, cut to the original. Property managers rekeying a block of doors typically use blanks for duplicates and random cut sets when each unit gets its own new key.

No. The Kwikset 81210-002 keys ship already cut to a random 6 pin bitting, so no cutting equipment is involved on your end. That is the practical split against a blank like the Emtek MS4-KEYBLKC, which is sold uncut on the Schlage C keyway and requires a key machine or a locksmith to cut before it will turn anything. Contractors and maintenance crews without cutting capability on site generally work from pre-cut keys for that reason.

Kwikset lists the 81210-002 extra cut keys as residential. They suit house, apartment, and light rental door hardware rather than commercial cylinder programs.

Keys only. The 81210-002 is supplied as extra cut keys, with no pins, springs, or cylinder parts. If you are pinning a 6-pin cylinder to one of these keys, order the pin kit separately.
