Corbin Russwin 487K19 67A1 626 – Frequently Asked Questions

1) Will a 487K19 plug work in my existing Corbin Russwin keyway if it isn't 67A1?
No. The plug is cut for the 67A1 keyway, so the keys in your system must be 67A1 blanks. A plug is keyway specific, and a 67A1 plug will not accept keys from a different Corbin Russwin section. If your building is keyed on another keyway, order the plug in that keyway rather than this one.
2) I need a complete mortise cylinder, not just a plug - what should I order instead of the Corbin Russwin 487K19 67A1?
The 487K19 67A1 is a 7-pin X Class cylinder plug for 1-3/4 inch mortise cylinders, so it is the keyed core piece rather than a full cylinder assembly. If you need a complete mortise cylinder ready to drop into the lock body, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder with a Schlage C keyway, and the Adams Rite 4036 is a Grade 1 mortise cylinder in the 4036 series. Both are complete cylinders you install as a unit rather than plugs you fit into an existing housing.
3) My exit device takes a rim cylinder, not a mortise cylinder - what replaces the Corbin Russwin 487K19 in that case?
The 487K19 67A1 is a mortise format plug sized for 1-3/4 inch mortise cylinders and will not serve a rim application. For rim-prepped devices, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam, and the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Choose the cam orientation your device requires.
4) Is a BEST interchangeable core the same thing as the Corbin Russwin 487K19 67A1 plug?
No. The 487K19 67A1 is a 7-pin X Class plug built for 1-3/4 inch Corbin Russwin mortise cylinder housings with the 67A1 keyway. BEST interchangeable cores such as the 1CB 150 series core or the 1CDF drill resistant patented 7-pin brass core are figure-eight cores that pull and replace with a control key in BEST-prepped housings. They are not interchangeable with a Corbin Russwin mortise plug, even though the 1CDF is also 7-pin.
5) Can I use the Corbin Russwin 487K19 67A1 plug to rekey a key-in-knob or key-in-lever lock?
No. The 487K19 67A1 is built to fit 1-3/4 inch Corbin Russwin mortise cylinder housings. Key-in-knob and key-in-lever locks take a different cylinder body: the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1599 is a key-in-knob replacement cylinder, the 1579 is a knob and lever cylinder for Sargent locks, and the Falcon A23161-05 G is a key in lever cylinder in the RU/T series with a 6-pin G keyway, keyed different with 2 cut keys.
6) I am replacing the outside cylinder on a deadbolt - is the Corbin Russwin 487K19 the right part?
The 487K19 67A1 is a mortise cylinder plug and is not a deadbolt cylinder. For deadbolt work, the Kaba Ilco 1549 is a key-in-deadbolt cylinder, and Medeco offers several retrofit options: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
7) Is a 7-pin plug worth it over a 6-pin for a master keyed building?
The seventh pin chamber gives you another level of key control and more room in a master key system, which is why the 487K19 is built to X Class with a 7-pin configuration. If your site is already running 6-pin cylinders on another platform, note the comparison: the Detex MC65 mortise cylinder is a 6-pin unit on the Schlage C keyway, and the Falcon A23161-05 G key-in-lever cylinder is 6-pin on the G keyway. Mixing pin counts and keyways across a facility means two key systems, so standardize before you order.
8) I need to rekey a Corbin Russwin mortise lock instead of replacing the whole cylinder. Is this what I order?
Yes, provided your system runs the 67A1 keyway. Swapping the plug lets you rekey the existing mortise cylinder housing rather than buying a new assembly, which is how locksmiths handle a tenant turnover or a lost master on a Corbin Russwin opening. Keep in mind the plug arrives as a replacement component, so you supply the pinning and the keys to match your system.
9) What are my options if I don't want to stay on the Corbin Russwin platform?
If you are re-standardizing rather than repairing, a few paths in the same category: the BEST 1CDF is a drill resistant patented 7-pin interchangeable core in the 150 Series if you want to keep seven pins and add key control; the BEST 1C5 is a standard 5-pin core for lower-security interior doors; and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder. Moving platforms means new keys for every opening you convert, so it only pays on a full changeover, not a single door.
10) I want a 5-pin core instead of 7-pin for a lower-security opening - what are my options?
The Corbin Russwin 487K19 67A1 plug is a 7-pin X Class configuration intended for enhanced key control. If the opening does not call for that level of key control, the BEST 1C5 is a standard 5-pin cylinder core, and the Adams Rite 4025 and 4026 are five pin tumbler cylinder pulls. Note that those are different form factors - a BEST core and a cylinder pull are not drop-in replacements for a Corbin Russwin mortise plug.
11) I need a non-keyed filler for a rim opening - does the Corbin Russwin 487K19 work?
No. The 487K19 67A1 is a keyed 7-pin X Class plug intended to provide working key control in a mortise cylinder. If the opening needs a cylinder shape with no keying function, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter fills a rim prep without operating anything.
12) Will the Corbin Russwin 487K19 67A1 work in an Adams Rite MS1847 storefront deadlock?
The 487K19 67A1 is a plug for 1-3/4 inch Corbin Russwin mortise cylinder housings and is not a storefront cylinder pull. For MS1847 deadlock and deadlatch systems, Adams Rite offers the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws. For a wood door deadlock, the 4026 five pin tumbler cylinder pull is designed for the Adams Rite 5017 wood door deadlock and deadlatch.
13) What is the difference between the Corbin Russwin 487K19 67A1 and a Schlage 20-057-C full size interchangeable core?
The 487K19 67A1 is a 7-pin X Class plug with the Corbin Russwin 67A1 keyway, made to fit 1-3/4 inch mortise cylinder housings and offered in 606 Satin Brass and 626 Satin Chrome. The Schlage 20-057-C is a full size interchangeable core cylinder with a Schlage C keyway in 643E Aged Bronze. The two run on different keyways and different housing systems, so they serve separate keying programs rather than substituting for one another.
14) I have an Emtek handleset that needs a replacement cylinder - is the Corbin Russwin 487K19 a match?
No. The 487K19 67A1 is a Corbin Russwin mortise cylinder plug on the 67A1 keyway and is not built for residential-style handlesets. For Emtek hardware, the Emtek CY4 cylinder is sold as a single piece, and Medeco offers the 1065244, a 5-pin rim lazy motion rim type cylinder supplied with an Emtek tailpiece.
15) Is this plug approved for commercial door hardware, or is it a residential part?
Commercial. Corbin Russwin lists the 487K19 67A1 as a commercial door hardware cylinder part, and it is the kind of component specified in offices, schools, healthcare, government buildings, multi-tenant residential, warehouses, and retail. It is an OEM Corbin Russwin cylinder part, so it holds factory tolerances for those housings.
