Emtek MS4-WEISERKYBLKC Key Blank - Weiser (WR5) Keyway

Yes. The MS4-WEISERKYBLKC blank is cut for either Schlage C or Weiser WR5, so one blank covers both keyways. That matters if you have a mix of Emtek locks in a house or small building keyed to different profiles, since you only need to stock the one blank to duplicate for both.

No. The Emtek MS4-WEISERKYBLKC is a Schlage C or Weiser WR5 profile blank and won't enter a Kwikset KW1 cylinder. For Kwikset cylinders, look at the Kwikset key blanks instead, such as the Kwikset 87615-001 for 6-pin knobs and deadbolts or the Kwikset 83559-008 large bow builder key. Kwikset also sells an 88485-005 blank for Schlage-keyed knobs and deadbolts if you're working a Schlage C opening but prefer the Kwikset part.

Both are uncut key blanks, not finished keys, so both go to a locksmith or a key machine before they open anything. The Emtek MS4-WEISERKYBLKC is cut for a Schlage C or Weiser WR5 keyway, so one part number covers cylinders in either of those two keyways. The Kwikset 88485-005 is described as a blank for knobs and deadbolts in Schlage, so it addresses the Schlage side only. If the doors on a property mix Schlage C and Weiser WR5 cylinders, the MS4-WEISERKYBLKC is the blank that serves both without a second line on the order.

No. The Kwikset 81804-001 is a control key blank, and a control key is the service key that removes or retains a cylinder, not the key a tenant or crew carries to operate the lock. The Emtek MS4-WEISERKYBLKC is an operating key blank for Schlage C or Weiser WR5 cylinders. A locksmith rekeying a Weiser WR5 opening needs the MS4-WEISERKYBLKC for the working keys; the 81804-001 answers a different job on the cylinder itself and will not substitute for it.

Emtek lists the MS4-WEISERKYBLKC blank as a residential part. For a locksmith or property manager, that means it belongs with Emtek's residential knobset, leverset, and deadbolt cylinders rather than a commercial masterkey system. If you're keying a commercial opening on a restricted or high-security keyway, this is the wrong blank.

It's an uncut key blank, sold as an Emtek replacement part. A locksmith or hardware counter cuts it to your existing key or to a new bitting. Nothing is keyed at the factory on this item.

No, and it's worth keeping them apart. The MS4-WEISERKYBLKC is a plain operating key blank on the Schlage C / Weiser WR5 profile. A control key is a separate part used to remove or reset a cylinder, and Kwikset sells one under 81804-001. If you're trying to pull a SmartKey or interchangeable core, an operating blank won't do it.

The Kwikset 83559-008 is a large bow builder key blank in 6 pin, so the head of the key is sized for handling and tagging during construction. The Emtek MS4-WEISERKYBLKC is a standard blank cut for Schlage C or Weiser WR5 cylinders. A general contractor running construction keying who wants the bigger bow for sorting and labeling would look at the 83559-008; a locksmith or property manager producing tenant keys for Schlage C or Weiser WR5 cylinders stays with the MS4-WEISERKYBLKC.

The Kwikset 87615-001 is a 6 pin blank for knobs and deadbolts, so it is the one to reach for when the cylinder is pinned to six chambers. The Emtek MS4-WEISERKYBLKC is specified by keyway rather than pin count, fitting Schlage C or Weiser WR5 cylinders. Confirm the keyway on the cylinder first and the pin stack second: a blank in the wrong keyway will not enter the plug no matter how the chambers are pinned.

One model is offered, MS4-WEISERKYBLKC, with no size, finish, or pack-quantity choices to select. Order the quantity of blanks you need; property managers rekeying a fleet of doors typically order several per opening so tenants and maintenance both carry one.

The MS4-WEISERKYBLKC is a mechanical key blank and Emtek classes it as non-electronic. Many Emtek electronic deadbolts still carry a mechanical key override cylinder, so what decides it is the keyway in that override cylinder: if it's Schlage C or Weiser WR5, this blank enters it.
