Corbin Russwin 293K03 59A2 626 – Frequently Asked Questions

1) Will a 59A2 keyway plug work with my existing Corbin Russwin keys?
Only if your system is keyed in 59A2. The 293K03 plug is cut for the 59A2 keyway, so it drops into a Corbin Russwin keying program using that keyway and will accept keys from a keyed-alike or master key set on that section. A plug in the wrong keyway will not take your existing keys, so match the keyway stamped on the cylinder you are servicing before ordering.
2) Can I use this plug on a 1-1/8 inch or 1-1/4 inch mortise cylinder?
No. This plug is sized for 3 inch mortise cylinder applications. Shorter mortise cylinders use a shorter plug, so a 3 inch plug is not a substitute. Measure the cylinder body length you are rebuilding before you order.
3) Will this Corbin Russwin plug fit a Schlage or Sargent cylinder?
No. It is a Corbin Russwin part cut to the Corbin Russwin 59A2 keyway, and plug dimensions and keyways do not cross between manufacturers. For Sargent knob and lever work, the Kaba Ilco 1579 cylinder is made for Sargent; for Schlage, stay with a Schlage cylinder such as the 20-021 or 20-022 rim cylinder.
4) I need a complete mortise cylinder, not just the plug - what should I order instead of the Corbin Russwin 293K03?
The Corbin Russwin 293K03 is a replacement plug for 3 inch mortise cylinders, so it is a component that goes into an existing cylinder housing rather than a finished cylinder. If you need a whole mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder cut to the Schlage C keyway, and the Adams Rite 4036 is a five-pin mortise cylinder in the 4036 Series carrying a Grade 1 rating with a 1/2 inch minimum door thickness. Both arrive as assembled cylinders ready to thread into a lock body.
5) My lock is a key-in-lever, not a mortise lock - what cylinder do I use instead of the Corbin Russwin 293K03?
The 293K03 plug is built for 3 inch mortise cylinder applications and will not fit a key-in-knob or key-in-lever chassis. For those, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1599 is a key-in-knob replacement cylinder, and the 1579 is a knob and lever cylinder for Sargent locks. Falcon's A23161-05 G is a key in lever cylinder in the RU/T Series with a 6-pin G keyway, keyed different and supplied with two cut keys.
6) If I want to rekey doors without pinning plugs like the 293K03, what interchangeable core option is there?
The Corbin Russwin 293K03 is a 7-pin plug pinned into a mortise cylinder, so rekeying means servicing the cylinder itself. For a system where a core is pulled and swapped instead, BEST interchangeable core cylinders cover that approach: the 1CDF is a drill resistant patented interchangeable core in 7-pin brass, 150 Series, the 1CB is a Peaks 150 Series interchangeable core, and the 1C5 is a standard 5-pin core. Schlage's 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, and the 20-057-C is an FSIC core in the C keyway with a 643E aged bronze finish.
7) I have an aluminum storefront with an Adams Rite deadlock - is the Corbin Russwin 293K03 the right part?
The 293K03 is a plug for 3 inch mortise cylinders used in Corbin Russwin mortise lock bodies, and the 59A2 keyway ties it to Corbin Russwin keying. For an Adams Rite MS1847 deadlock or deadlatch, the cylinder pulls are the matched parts: the 4024 mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull with through-screws. For a wood door application on the Adams Rite 5017 deadlock or deadlatch, the 4026 five pin tumbler cylinder pull is the designated item.
8) What finishes does the 293K03 plug come in?
Two: 606 satin brass and 626 satin chrome. Pick to match the cylinder collar and the rest of the trim on the door, since the plug face is the visible part once it is installed.
9) Why choose a 7-pin plug over a 6-pin for a commercial building?
Seven pin chambers give more key cutting combinations, which matters when you are running deep master keying and want tighter key control across a large facility. The 293K03 is the 7-pin version for 3 inch Corbin Russwin mortise cylinders. If your building is standardized on 6-pin, a 6-pin cylinder like the Detex MC65 or the Schlage 20-021 rim cylinder is the family to stay in rather than mixing pin counts.
10) I need to rekey Corbin Russwin mortise locks across a whole building. Is buying plugs the right approach?
It works if the cylinder bodies are sound and you are staying in the same keyway. Swapping plugs like the 293K03 lets a locksmith reconfigure existing 3 inch mortise cylinders instead of replacing them, which keeps the collars and trim on the doors untouched. If instead you want to change cores without a locksmith on every call, an interchangeable core platform is the better route, for example the BEST 1CB 150 Series or the BEST 1CDF drill resistant 7-pin core, or a full size interchangeable core setup such as the Schlage 20-057 FSIC.
11) What is the fewest-pin alternative if I do not need the seven-pin depth of the Corbin Russwin 293K03?
The 293K03 uses a seven-pin tumbler arrangement for deeper key control. Where five pins are sufficient, the Adams Rite 4036 mortise cylinder is a five-pin unit in the 4036 Series rated Grade 1, and the BEST 1C5 is a standard 5-pin cylinder core. Pin count should match the keying system already in place at the facility so keys and masters continue to work.
12) Is the Corbin Russwin 293K03 a residential deadbolt cylinder?
No - the 293K03 is designated for commercial use as a mortise cylinder replacement part. Cylinders aimed at residential handleset and deadbolt retrofits are a different family: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder. Emtek also lists the CY4 cylinder sold each.
13) I just need to fill a cylinder hole with no key function - does the 293K03 work for that?
No. The Corbin Russwin 293K03 is a keyed 7-pin plug on the 59A2 keyway, meant to restore working key function in a mortise cylinder. For a non-functioning filler, the BEST 12E Series dummy rim cylinder measures 1-5/32 inch in diameter and occupies the prep without operating anything.
14) Is this a residential or commercial part?
Commercial. The 293K03 plug is built for commercial mechanical lock service work, the kind of rekeying and cylinder maintenance done in offices, schools, healthcare facilities, government buildings and multi-tenant properties.
15) Does the finish choice on the Corbin Russwin 293K03 limit what I can match on nearby hardware?
The 293K03 plug comes in 606 satin brass and 626 satin chrome, which covers the two most common commercial cylinder tones. If a darker cylinder is wanted on adjacent openings, Schlage's 20-057-C full size interchangeable core is listed in 643E aged bronze. Cylinder finish is usually chosen to match the escutcheon or lever trim already on the door.
