Weslock SC12987X1 Schlage Keyway Cylinder for Traditional and Elegance

It's a replacement key cylinder for Weslock Traditional and Elegance door hardware, cut to the Schlage keyway. You're buying the keyed plug assembly only, not a complete lockset, so it goes into hardware you already have on the door when you want to rekey or swap the keying rather than replace the lock.

That's the point of it. The cylinder uses the Schlage keyway, so a Weslock Traditional or Elegance lock fitted with it takes a Schlage-profile key blank and can be keyed alike with Schlage cylinders on the rest of the building. Property managers running mixed hardware use this to get one key across doors that came from two different manufacturers. The keying itself still has to be done by your locksmith.

Traditional and Elegance hardware only. Weslock builds cylinders to a specific collection, so if the lock on your door is from another Weslock line, this plug is the wrong part. Check which collection the existing hardware is before ordering.

No. It's a residential key-in-lever plug for Weslock Traditional and Elegance, not a mortise or rim cylinder, and it has neither a mortise thread nor a rim tailpiece. For a mortise lock you want something like the Corbin Russwin 1000 Series Grade 1 mortise cylinder in 1-1/2 inch with an A02 straight cam, or the Detex MC65 in 1-1/8 inch 6-pin with a Schlage C keyway. For an exit device you need a rim cylinder such as the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal cam.

No - the SC12987X1 is the Schlage keyway cylinder made for Weslock Traditional and Elegance trim. For Sargent knob and lever hardware the part written for it is the Kaba Ilco 1579 knob and lever cylinder for Sargent. For Falcon, the A23161-05 G is a key-in-lever cylinder for the RU/T series with a 6-pin G keyway, keyed different, supplied with two cut keys. Key-in-knob and key-in-lever cylinders are cut to the manufacturer's housing, so the brand of the lock decides the cylinder.

The SC12987X1 is the Schlage keyway cylinder for Weslock Traditional and Elegance trim. For a deadbolt the parts written for that function are the Kaba Ilco 1549 Series Key-In-Deadbolt Cylinder and the Kaba Ilco 1599 key-in-knob replacement cylinder, both listed with a deadbolt function. Medeco offers retrofit deadbolt cylinders as well: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Match the part to the lock family you are working on rather than assuming a knob cylinder transfers.

The Weslock SC12987X1 serves Weslock Traditional and Elegance residential trim, not narrow stile storefront hardware. For aluminum storefront the Adams Rite parts are the ones written for it: the 4036 is a mortise cylinder with five-pin security, Grade 1, with a 1/2 inch minimum door thickness. Where the opening uses an MS1847 deadlock or deadlatch, the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull with through-screws, both designed for the MS1847. For a wood door the 4026 five pin tumbler cylinder pull is designed for the Adams Rite 5017 wood door deadlock or deadlatch.

For a key-in-knob or key-in-lever cylinder the closest cross-brand match by function is the Kaba Ilco 1539 Series Key-In-Knob / Lever Universal Cylinder, which is built as a universal knob and lever cylinder rather than a Weslock-specific part. From Schlage the nearest catalog parts are rim cylinders rather than knob cylinders: the Schlage Commercial 20-021 rim cylinder is a 6-pin with a vertical tailpiece cam and two keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. The Weslock SC12987X1 is the cylinder for Weslock Traditional and Elegance trim and carries the Schlage keyway, so it drops into those Weslock housings directly while the Ilco and Schlage parts are chosen by the housing they are going into.

The Weslock SC12987X1 is the cylinder that serves Weslock Traditional and Elegance trim, so a mortise lock body needs a mortise cylinder instead. The Detex MC65 is a mortise cylinder with a Schlage C keyway, 1-1/8 inch, 6-pin, commercial grade. From Corbin Russwin the 1000 Grade 1 series mortise cylinder comes 1-1/2 inch with an A02 straight cam, and the 1070 Grade 1 series is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. Mortise cylinders are selected by length and cam, so confirm both against the lock body before ordering.

The SC12987X1 is a fixed Schlage keyway cylinder built for Weslock Traditional and Elegance trim, so it is rekeyed by pinning rather than by swapping a core. A facility standardized on interchangeable cores would look at the BEST 1C Series standard 5-pin cylinder core, the BEST Peaks 1CB 150 Series interchangeable core cylinder, or the BEST 1CDF drill resistant patented interchangeable core 7-pin brass 150 Series part. On the Schlage side the 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and two keys, and the 20-057-C is a full size interchangeable core in the C keyway, 643E aged bronze. Interchangeable core systems let maintenance rekey an opening in seconds without pulling the lock apart.

The Weslock SC12987X1 carries the Schlage keyway on Weslock Traditional and Elegance trim, which keeps residential-style openings on the same key. Across other lock types in the same keyway: the Detex MC65 is a mortise cylinder with the Schlage C keyway, 1-1/8 inch, 6-pin, commercial grade; the Schlage 20-057-C is a full size interchangeable core in the C keyway in 643E aged bronze; and the Corbin Russwin 1080 Grade 1 series is a 1-1/2 inch LFIC 6-pin mortise cylinder built for Schlage L9000 mortise locks with an A01 Schlage L cam. That combination lets one key system carry knob, mortise, and interchangeable core openings.

Six: Bright Chrome, Satin Chrome, Black, Antique Brass, Lifetime Brass, and Oil Rubbed Dark Bronze. Match the cylinder face to the rose and lever already on the door, since the plug face is the visible part once installed.

Swapping in Schlage keyway cylinders like the SC12987X1 works when the hardware is Weslock Traditional or Elegance and you just want one key profile across the site. If you're managing a facility and expect to rekey doors repeatedly, interchangeable core is the better system, because a core pulls with a control key instead of dismantling the lock. BEST covers that end with the 1C Series standard 5-pin core and the 1CB Peaks 150 Series core; Schlage's 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam.

The cylinder takes the Schlage key profile, which is what lets it be keyed alike or master keyed together with other Schlage-keyway cylinders by a locksmith. If you need cylinders that ship already cut with keys, the Falcon A23161-05 G key-in-lever cylinder comes keyed different with two cut keys, and the Schlage 20-021 and 20-022 rim cylinders each come with two keys.

The SC12987X1 is the Schlage keyway cylinder that goes into Weslock Traditional and Elegance trim, and it is offered in Oil Rubbed Dark Bronze, Black, Bright Chrome, Antique Brass, Lifetime Brass, and Satin Chrome. A rim cylinder is a different part that mounts through the door and drives a surface-applied lock with a tailpiece: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the horizontal tailpiece cam version, while the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. The two are not interchangeable because the tailpiece and mounting are what determine fit.

The Weslock SC12987X1 is keyed to Weslock Traditional and Elegance trim, so an Emtek handleset takes an Emtek-fit part. The Emtek CY4 cylinder is sold each. For a high security upgrade on the same hardware, the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and the Emtek handleset and deadbolt outside cylinder, and the Medeco 1065244 is a 5-pin rim lazy motion rim type cylinder supplied with an Emtek tailpiece.

A dummy cylinder fills the hole and gives the trim its finished look without any keying function - the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is that part. It is not a substitute for the Weslock SC12987X1, which is the working Schlage keyway cylinder for Weslock Traditional and Elegance trim. Cylinder pulls are another part that reads like a cylinder in a catalog but does a different job: the Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock systems, providing the door pull and the cylinder position together.
