Corbin Russwin 293K03 59A1 626 – Frequently Asked Questions

1) Will a 293K03 plug work in my existing Corbin Russwin keying system?
Only if your system runs the 59A1 keyway. This plug is cut for 59A1, so it accepts 59A1 key blanks and pins into an existing 59A1 masterkey system. A plug in a different Corbin Russwin keyway will not take your keys, so verify the keyway stamped on the cylinder you are rebuilding before ordering.
2) Can this plug be used in a rim cylinder or a key-in-knob lock?
No. It is cut for a 3 inch mortise cylinder housing only. For rim applications use a rim cylinder such as the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal cam. For key-in-knob or lever replacement, a Kaba Ilco 1539 universal knob/lever cylinder or the Falcon A23161-05 G key-in-lever cylinder is the correct type.
3) If I need a complete mortise cylinder rather than just a replacement plug, what should I order instead of the Corbin Russwin 293K03?
The Corbin Russwin 293K03 is a 7-pin plug, a replacement component intended to go into an existing 3 inch mortise cylinder housing rather than a whole cylinder. If the housing itself is damaged or missing, order a complete mortise cylinder instead: the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a five-pin mortise cylinder in the 4036 Series rated Grade 1. Both arrive as assembled cylinders, so they replace the full unit rather than repinning what is already in the door.
4) Can I use an interchangeable core in place of the Corbin Russwin 293K03 plug?
No, they are different systems. The 293K03 is a 7-pin plug that fits inside a 3 inch Corbin Russwin mortise cylinder and uses the 59A1 keyway. An interchangeable core such as the BEST 1CB in the 150 Series, or the BEST 1CDF drill-resistant patented 7-pin brass core, pulls out with a control key and requires an interchangeable-core housing in the door. If your hardware is not already set up for IC, the plug is the part that restores the existing cylinder; if you want core swapping without repinning, you need IC-prepped hardware and a core like the 1CB or 1CDF.
5) I have a rim exit device, not a mortise lock. Is the Corbin Russwin 293K03 the wrong part?
Yes. The 293K03 is sized for 3 inch mortise cylinder housings, which are threaded and used with mortise locks. A rim exit device takes a rim cylinder with a tailpiece: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam, the 20-022 is the same cylinder with a horizontal cam, and the Schlage 20-057 is a 6-pin full-size interchangeable core rim cylinder with a convertible tailpiece cam. Match the cam orientation to what your device requires.
6) Will the Corbin Russwin 293K03 work in a key-in-lever or key-in-knob lockset?
No. The 293K03 is a plug for 3 inch mortise cylinder assemblies. Key-in-knob and key-in-lever locksets take a different cylinder body: the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the 1579 is the knob and lever cylinder for Sargent, the 1599 is a key-in-knob replacement cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway supplied keyed different with two cut keys. Choose by the lockset brand you are servicing.
7) Do keys come with the Corbin Russwin 293K03 plug?
No keys or pins are part of it. The 293K03 ships as the bare 7-pin plug in 59A1, so a locksmith supplies the pinning kit and cuts 59A1 blanks to the system. Cylinders that arrive keyed with cut keys are a different purchase, for example the Schlage 20-021 rim cylinder which is supplied with two keys.
8) What is the closest thing to the Corbin Russwin 293K03 if I only need a bare pinned plug or core rather than a housing?
The 293K03 is the 7-pin plug alone, sold as a replacement part for Corbin Russwin mortise cylinders in the 59A1 keyway. The comparable bare-plug and bare-core items are the BEST 1C5 standard 5-pin cylinder core and the BEST 1CB 150 Series interchangeable core. Those are BEST-system parts and do not enter a Corbin Russwin mortise housing, so they suit a BEST-prepped opening rather than a 59A1 Corbin Russwin system.
9) I need to key an aluminum storefront deadlock. Is the Corbin Russwin 293K03 what I need?
Not by itself. The 293K03 is a 7-pin plug for a Corbin Russwin 3 inch mortise cylinder in the 59A1 keyway. For an Adams Rite storefront deadlock, the cylinder pulls are matched to the lock: the 4024 mounts with a trim plate and the 4025 uses through-screws, both for the MS1847 deadlock/deadlatch, while the 4026 is a five-pin tumbler cylinder pull for the 5017 wood door deadlock/deadlatch. The Adams Rite 4036 mortise cylinder is Grade 1 with a 1/2 inch minimum door thickness.
10) What should I use instead of the Corbin Russwin 293K03 on a residential deadbolt or handleset?
The 293K03 is a commercial part for Corbin Russwin mortise cylinders. For deadbolts and handlesets, the retrofit cylinders are different items: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. The Emtek CY4 is a cylinder sold each for Emtek hardware.
11) I need a cylinder that looks right but does not key anything. Does the Corbin Russwin 293K03 do that?
No. The 293K03 is a working 7-pin plug that restores keyed operation in a Corbin Russwin 3 inch mortise cylinder. For an opening that needs the appearance of a cylinder with no keying function, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the item built for that purpose.
12) How does the pin count of the Corbin Russwin 293K03 compare to other cylinders I might standardize on?
The 293K03 uses a 7-pin tumbler arrangement in the 59A1 keyway. Among the alternatives, the BEST 1CDF is also a 7-pin core, in drill-resistant patented brass. Six-pin options include the Detex MC65 mortise cylinder in Schlage C, the Falcon A23161-05 G key-in-lever cylinder in the G keyway, and the Schlage 20-021 and 20-022 rim cylinders. Five-pin options include the BEST 1C5 core and the Adams Rite 4036 mortise cylinder. Higher pin counts give more key differs for a large master key system; the pinning must match the keyway family you already maintain.
13) My deadbolt cylinder failed. Is the Corbin Russwin 293K03 a deadbolt cylinder?
No. The 293K03 is a plug for 3 inch mortise cylinder assemblies on commercial mortise locks. For deadbolt cylinder function, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, and the 1539, 1579 and 1599 Series are also listed for deadbolt function. Those are the parts to look at when the deadbolt cylinder itself is being replaced.
14) Is the 293K03 suitable for commercial buildings like schools and hospitals?
Yes, it is a commercial-duty part. Corbin Russwin lists it for office buildings, schools, healthcare, government facilities, retail, warehouses, and multi-tenant residential, which is the traffic level a 7-pin mortise cylinder is normally specified for.
15) Does a finish match exist if I need the Corbin Russwin 293K03 in something other than brass, or do I need a different brand?
No need to change brands for finish. The Corbin Russwin 293K03 7-pin plug is offered in 606 Satin Brass and 626 Satin Chrome, so it can be matched to either brass-tone or chrome-tone trim on the same opening. Among the alternatives, the Schlage 20-057-C full-size interchangeable core is listed in 643E Aged Bronze, which is a darker tone and a different cylinder type.
