Corbin Russwin 574K07 252 626 – Frequently Asked Questions

1) Will the Corbin Russwin 574K07 plug fit a CK4455 cylinder made after August 1993?
No. The 574K07 standard plug is specified for CK4455 and CK4482 cylinders manufactured before 8/93. Corbin Russwin changed those cylinders after that date, so on a post-8/93 cylinder this plug is the wrong part. Check the date of the cylinder body before you pull it apart.
2) Which Corbin Russwin keyways can I order this cylinder plug in?
Ten keyways: 60, 70, 252, 750, 751, 752, 852, 981, 982 and 983. The plug has to match the keyway of the system it is going into, so pull a key and confirm the keyway stamp before ordering. Each keyway is offered in both finishes.
3) Can I rekey an old Corbin Russwin cylinder without buying a whole new one?
That is what this part is for. The 574K07 is sold as an individual plug, so a locksmith servicing a CK4455 or CK4482 can swap just the plug and keep the existing cylinder shell in the door. It keeps the opening on the same Corbin Russwin keying system instead of forcing a new cylinder and new key control.
4) If I need to replace a whole cylinder rather than just rebuild one, what should I order instead of the Corbin Russwin 574K07?
The 574K07 252 is an individual standard cylinder plug, a replacement component used to service an existing CK4455 or CK4482 cylinder made before 8/93 rather than to replace the cylinder outright. If the cylinder body itself is damaged or you want a complete unit, order a full cylinder instead: the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway, and the Schlage 20-021 and 20-022 are complete 6-pin rim cylinders supplied with two keys, the 20-021 with a vertical tailpiece cam and the 20-022 with a horizontal cam. Note those are different keying systems, so they will not key into an existing Corbin Russwin 252 system.
5) Is a BEST interchangeable core an equivalent to the Corbin Russwin 574K07 plug?
No. The 574K07 252 is a 5 and 6-pin individual plug that goes inside a Corbin Russwin CK4455 or CK4482 cylinder built before 8/93, so the surrounding cylinder housing stays in the door. A BEST 1C5 is a standard 5-pin cylinder core, and the 1CB is a 150 Series interchangeable core, both of which are removable cores that drop into BEST figure-eight core housings. They are a different servicing approach and a different keyway family, so neither works as a plug in a Corbin Russwin cylinder.
6) Does the 574K07 come in 5-pin or 6-pin?
Both. The 574K07 is an individual standard plug drilled to take either a 5-pin or a 6-pin arrangement, so one plug covers both chamber counts on compatible CK4455 and CK4482 cylinders. You pin it to match the existing cylinder.
7) My Corbin Russwin cylinder is not a CK4455 or CK4482. What should I look at instead?
The 574K07 plug is keyed to those two legacy cylinder bodies only, so it is not a general Corbin Russwin plug. If you are replacing the whole cylinder rather than servicing one, look at a complete cylinder instead: the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder, and Schlage's 20-021 and 20-022 are 6-pin rim cylinders with vertical and horizontal tailpiece cams respectively. Those are replacements, not parts, so they carry their own keyway.
8) If I am standardizing a building on interchangeable cores, is this plug the right direction?
No. The 574K07 is a fixed standard plug for legacy Corbin Russwin cylinders, so it keeps you on conventional keying. Facilities moving to removable cores for faster rekeying usually go to a core system instead, such as the BEST 1C Series standard 5-pin core or the Schlage 20-057 6-pin full size interchangeable core with a convertible tailpiece cam. Use the 574K07 when the goal is to preserve the existing Corbin Russwin system, not replace it.
9) I have a key-in-lever or key-in-knob lock to rekey, not a mortise cylinder. What is the right part?
The Corbin Russwin 574K07 252 plug serves CK4455 and CK4482 cylinders and is not a key-in-knob part. For key-in-lever and key-in-knob work, the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder, the 1579 is a knob and lever cylinder made for Sargent locks, and the 1599 is a key-in-knob replacement cylinder. Falcon also offers the A23161-05 G, a key-in-lever cylinder for RU/T Series in 6-pin G keyway, keyed different with two cut keys.
10) For a deadbolt instead of a lock cylinder rebuild, what takes the place of the 574K07?
The 574K07 252 plug is a rebuild component for CK4455 and CK4482 cylinders, not a deadbolt cylinder. For deadbolt applications, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, and Medeco offers the 1012040, a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1075127, a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
11) I am servicing an aluminum storefront with an Adams Rite deadlock, not a Corbin Russwin cylinder. What do I use?
The Corbin Russwin 574K07 252 plug only fits CK4455 and CK4482 cylinders made before 8/93 and has no application in Adams Rite storefront hardware. For those openings, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security rated for a 1/2 inch minimum door thickness, and the 4024 and 4025 cylinder pulls are designed for the Adams Rite MS1847 deadlock/deadlatch, the 4024 with trim plate mounting and the 4025 with through-screws. For wood doors, the 4026 five pin tumbler cylinder pull suits the Adams Rite 5017 wood door deadlock/deadlatch.
12) Which cylinder options give higher key control or drill resistance than a standard 574K07 plug?
The Corbin Russwin 574K07 252 is described as a standard plug, offered across keyways including 252, 60, 70, 750, 751, 752, 852, 981, 982 and 983 to match an existing Corbin Russwin keying system. If you are specifying new hardware and want patented key control or drill resistance rather than matching legacy keying, the BEST 1CDF is a drill resistant Preferred patented interchangeable core 7-pin brass 150 Series core. Note that moving to a patented system means a separate key system from your existing Corbin Russwin cylinders.
13) What is the difference between ordering the 574K07 plug and ordering a full size interchangeable core cylinder?
The Corbin Russwin 574K07 252 is a single plug used to rebuild or rekey an existing CK4455 or CK4482 cylinder, keeping the original cylinder housing in service. A full size interchangeable core setup works differently: the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam supplied with two keys, and the 20-057-C is a full size interchangeable core in C keyway with a 643E aged bronze finish. With FSIC, the core is swapped as a unit; with the 574K07, the plug itself is the serviced part.
14) What finishes does the Corbin Russwin 574K07 plug come in?
Two: 606 satin brass and 626 satin chrome. Both are available across every keyway offered. The plug face is the only part of this component that shows, so match it to the cylinder ring or collar already on the door rather than to the lock body.
15) Is the 574K07 plug a commercial part or is it for residential locks?
Commercial. It is a replacement component for Corbin Russwin mechanical lock cylinders in commercial and institutional buildings, the kind of legacy hardware still running in schools, hospitals and municipal facilities. It is not a residential deadbolt part.
16) Can I use a dummy cylinder in place of the 574K07 plug?
No. The 574K07 252 is a functioning 5 and 6-pin standard plug that carries the keying in a CK4455 or CK4482 cylinder. The BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is a non-keyed filler used where a cylinder appearance is needed without lock function, so it will not restore key operation to a Corbin Russwin cylinder.
