Kwikset 89991-001 – Frequently Asked Questions
1) What is the difference between the Kwikset 89991-001 control key blank and the Emtek MS4-KEYBLKC key blank?
They are cut for different keyways and serve different purposes. The Kwikset 89991-001 is a Signatures control key blank, used to operate the control function on Kwikset Signatures cylinders rather than to make an everyday entry key. The Emtek MS4-KEYBLKC is an ordinary key blank cut to the Schlage C keyway, so it is the blank to order when the cylinder in the door is Schlage C keyed. A locksmith stocking both keeps them separate: the control blank is a service tool, the Schlage C blank is a duplication blank.
2) I need blanks for Schlage C keyed cylinders - will a Kwikset Signatures control key blank work?
No. Schlage C is a different keyway, and a blank has to match the keyway of the cylinder it goes into. For Schlage C cylinders, the Emtek MS4-KEYBLKC is the blank cut to that keyway. The Kwikset 89991-001 Signatures control key blank belongs with Kwikset Signatures cylinders. Property managers running a mixed building usually end up carrying both rather than trying to substitute one for the other.
3) Does the Kwikset 89991-001 key blank come cut, or do I need to have it cut?
It ships as a blank. The 89991-001 is an uncut Signatures control key blank, so a locksmith or anyone with a key machine has to cut it to the control code for your cylinders before it will operate anything. Buying it is the first half of the job, not the whole job.
4) Is this Kwikset control key blank a rekeying tool or a spare house key?
It's a service item, not a spare key for a tenant. The Signatures control key blank is sold as a rekeying tool, the key a locksmith or maintenance tech cuts to control the cylinder rather than to unlock the door day to day. If you just want extra door keys for an SC1 Kwikset lock, a standard SC1 house key blank is what you want instead.
5) What other SC1 key blanks could I buy if the Kwikset Signatures blank isn't the right one?
Emtek sells an SC1 blank as well, the MS4-KEYBLKC, cut on the Schlage C keyway, which is the same key section SC1 refers to. It is a general key blank rather than a Signatures control key blank, so use it for duplicating keys on Schlage C keyway cylinders, not for controlling a Kwikset Signatures cylinder.
6) Is a control key blank the same thing as a spare key blank for the same lock?
No, and mixing them up costs a service call. The Kwikset 89991-001 is a control key blank for Kwikset Signatures - the key that operates the control function on the cylinder, not the key a tenant carries. A general-purpose blank such as the Emtek MS4-KEYBLKC, cut to the Schlage C keyway, is what gets duplicated for users. If you are handing keys to residents, you want user blanks; the control blank stays with whoever services the cylinders.
7) Can I use the Kwikset 89991-001 control key blank on commercial openings in my building?
The Signatures control key blank is a residential-grade item. For commercial door hardware programs, standardize on commercial cylinders and their own control keys rather than carrying this one in the truck for institutional work.
8) Is there more than one version of the Kwikset Signatures control key blank to choose from?
One model only, 89991-001. There's no finish, length, or keyway choice to make on the order, so the only thing to confirm before ordering is that your cylinders take an SC1 key section.
