Kwikset 81057-007 Set of 8 Keys/Ringed

The 81057-007 is a set of 8 ringed keys cut for 5-pin Kwikset cylinders, so they fit Kwikset residential cylinders using the standard 5-pin Kwikset keyway. They are extra cut keys, meaning they come cut to a factory key code rather than blank, so they only turn locks already keyed to that same code. If you need keys for locks already installed and keyed on your doors, take an existing working key to a locksmith for duplication instead.

They come cut. The 81057-007 is a set of 8 extra cut 5-pin keys on a ring, not uncut stock, so no key machine is needed. That makes them useful when you want additional keys to a lockset's factory code, but it also means they cannot be cut to match a different existing key.

The 81057-007 is the wrong part for Schlage cylinders. Kwikset and Schlage keyways are not interchangeable, and the 81057-007 keys come pre-cut to a Kwikset 5-pin code. For a Schlage C keyway blank you can cut yourself, the Emtek MS4-KEYBLKC key blank is the Schlage C option.

No. The Emtek MS4-KEYBLKC is a key blank cut to the Schlage C keyway, so it enters Schlage C cylinders only and still has to be cut to a bitting before it opens anything. The Kwikset 81057-007 is a set of 8 extra cut keys on a ring, 5 pin, supplied already cut rather than as blank stock. Different keyway family and different state of the key, so one does not stand in for the other on a Kwikset cylinder.

No. These are residential keys cut for a 5-pin Kwikset keyway, which is what you find on Kwikset knobs, levers and deadbolts in homes and apartments. Commercial mortise and rim cylinders on a building master key system use a different keyway and are keyed by your locksmith to that system, so a factory-cut residential key will not operate them.

The Kwikset 81057-007 ships as extra cut keys, 5 pin, in a ringed set of 8 - they arrive bitted and ready to hand out, which suits a property manager who needs more working keys for an existing Kwikset cylinder. If the job is cutting your own on a duplicator, the Emtek MS4-KEYBLKC is uncut blank stock in the Schlage C keyway, intended to be bitted at the counter. Match the blank to the cylinder keyway before buying: Schlage C stock will not feed a Kwikset cylinder.

Eight keys on one ring covers a typical unit turnover well: tenant copies, a spare for the office, and one for a maintenance tech, all matching the same 5-pin Kwikset code. For a fleet of units on different codes you need a set per code, since these are cut keys rather than blanks and the cut is fixed.
