KSP 400K-KMT300 – Frequently Asked Questions
1) What is the difference between the KSP 400K-KMT300 key blank and the Emtek MS4-KEYBLKC?
They are keyway-specific blanks and are not interchangeable with each other. The Emtek MS4-KEYBLKC is cut for the Schlage C keyway, so it is the one to pick when the cylinder you are duplicating for is Schlage C. The KSP 400K-KMT300 is a key blank ordered by its own model, 400K-KMT300, and is used where that blank matches the cylinder. A blank only works in the keyway it was made for, so confirm the keyway stamped on the cylinder or plug before ordering either.
2) Is a control key the same thing as a key blank like the KSP 400K-KMT300?
No, and this is a common mix-up when ordering. Kwikset 81804-001 is a control key blank - a control key is the key that removes or retains an interchangeable core, not the key that operates the lock for a tenant or employee. The KSP 400K-KMT300 is an operating key blank. If you are rekeying doors and hand out control key blanks by mistake, they will not do the job the occupants need. Order the control blank only when you are managing cores.
3) I need a blank for Schlage cylinders but want to stay with Kwikset packaging - what is the equivalent?
Kwikset makes a Schlage-keyway blank under 88485-005, described as knobs and deadbolts, Schlage, so it covers Schlage-keyed knob and deadbolt cylinders while staying in the Kwikset line. Emtek MS4-KEYBLKC is the other Schlage C option. Both are alternatives to the KSP 400K-KMT300 when the opening you are keying uses a Schlage cylinder rather than the keyway the KSP blank is cut for.
4) For a 6-pin cylinder, what blanks should I be looking at alongside the KSP 400K-KMT300?
Two Kwikset options are stated as 6-pin. The 83559-008 is a large bow builder key, 6 pin - the large bow gives a bigger head to grip and to tag, which suits a builder or construction key handed around a site. The 87615-001 is a 6-pin blank for knobs and deadbolts. Pin count has to match the cylinder: a 6-pin blank will not work in a 5-pin cylinder that is cut for a shorter blade. Confirm the pin count of the cylinder you are duplicating for before you pick between these and the KSP 400K-KMT300.
5) I am standardizing keying across a building - can I stock one blank for all the doors?
Only if every cylinder shares the same keyway and pin count. The blanks that serve this space split along both lines: Emtek MS4-KEYBLKC and Kwikset 88485-005 are Schlage keyway, Kwikset 87615-001 and 83559-008 are 6-pin, 83559-008 in a large bow, Kwikset 81804-001 is a control key blank for cores, and the KSP 400K-KMT300 is its own model. Survey the cylinders on the doors first, then stock the blank that matches the keyway you are standardizing on rather than assuming one blank covers the building.
