Corbin Russwin 564K52 A1 626 – Frequently Asked Questions

1) What does "Old Tailpiece" mean on the 564K52, and how do I know I need it?
Old Tailpiece is the legacy tailpiece configuration used on earlier CK4429 Hotel lock builds. Pull the existing plug and compare the tailpiece before you order; if the lock is a later build with the newer tailpiece, this plug is the wrong part even though the keyway and pinning match. On legacy CK4429 installations the Old Tailpiece version is the correct authentic replacement.
2) Which Corbin Russwin keyways can I get this hotel lock plug in?
All 24 keyways in the A family are available: A1 through A24. You order the plug in the keyway that matches the building's existing Corbin Russwin system, otherwise the master and guest keys already cut for the property won't enter. If you are unsure, read the keyway stamp off a plug you already have in service.
3) My lock isn't a Corbin Russwin CK4429. What replacement cylinder should I look at instead?
This plug only fits the CK4429, so for other hardware you need a cylinder built for that brand. For knob and lever locks there are universal-style options such as the Kaba Ilco 1539 key-in-knob/lever cylinder, the Kaba Ilco 1599 key-in-knob replacement cylinder, or the Kaba Ilco 1579 for Sargent locks. For exit device rim applications, the Schlage 20-021 (vertical tailpiece cam) and 20-022 (horizontal tailpiece cam) are 6-pin rim cylinders. Adams Rite deadlocks take the Adams Rite 4036 mortise cylinder.
4) Is a Schlage 20-021 rim cylinder a substitute for the Corbin Russwin 564K52 plug?
No. The Schlage Commercial 20-021 is a complete 6-pin rim cylinder with a vertical tailpiece cam supplied with two keys, and the 20-022 is the same rim cylinder with a horizontal tailpiece cam. The Corbin Russwin 564K52 is an individual plug for the CK4429 hotel lock with the Old Tailpiece configuration in the A keyway, intended for rebuilding an existing Corbin Russwin cylinder. The two are different parts of a lock, and a rim cylinder does not mount in a CK4429 hotel lock cylinder.
5) If the whole cylinder on a CK4429 hotel lock needs replacing rather than just the plug, what should be used instead of the Corbin Russwin 564K52?
The Corbin Russwin 564K52 is supplied as an individual standard plug for the CK4429 hotel lock series, so it addresses the plug alone rather than a full cylinder assembly. When the complete cylinder is being swapped out, a full cylinder is the better fit: the BEST 1C Series standard 5-pin cylinder core and the BEST Peaks 1CB 150 Series interchangeable core cylinder are complete core units, and the Detex MC65 is a 6-pin mortise cylinder with a 1-1/8 inch length in the Schlage C keyway. Note those carry their own keyways, so they will not follow an existing Corbin Russwin A-keyway key system the way the 564K52 does.
6) Which cylinder should be specified for an aluminum storefront deadlock rather than the Corbin Russwin 564K52?
Storefront deadlocks take an Adams Rite cylinder, not a hotel lock plug. The Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security in the 4036 Series, rated for a 1/2 inch minimum door thickness. For cylinder pulls, the 4024 mounts with a trim plate and the 4025 uses through-screws, both for the MS1847 deadlock and deadlatch, while the 4026 five pin tumbler cylinder pull is intended for the 5017 wood door deadlock and deadlatch.
7) What finishes does the Corbin Russwin 564K52 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the visible cylinder face on the rest of your guest room doors, since the plug face is the part you see through the trim. Satin chrome is the usual match for brushed or satin nickel trim, satin brass for brass hardware.
8) Can I use this plug to rekey guest room locks to a new hotel master system?
Yes, that's the normal use. Swapping in fresh plugs in the correct A-family keyway lets you re-establish key control on CK4429 Hotel locks room by room without pulling complete cylinders. Order the keyway that your new system is built on, and keep the finish consistent across the floor.
9) Would an interchangeable core be a better way to manage keying than replacing plugs?
Different approach entirely. A plug like the 564K52 is pinned and fitted inside the existing CK4429 cylinder, so a rekey means bench work. An interchangeable core system, for example the BEST 1C standard 5-pin core, the BEST 1CB 150 Series core, or the Schlage 20-057 full size interchangeable core rim cylinder, lets staff pull and swap a core with a control key in seconds. If you are staying with CK4429 hotel locks, the plug is the part that fits; if you are re-hardwaring and want fast turnover, look at the IC systems.
10) I need drill resistance and patented key control for a high-security area. Is this the right plug?
No. The 564K52 is a standard plug, not a high-security one, and nothing in its specification covers drill resistance or patented key protection. For that requirement look at a drill-resistant patented core such as the BEST 1CDF 7-pin interchangeable core, or a Medeco cylinder. Understand that going that route changes the keyway, so those openings come off your existing Corbin Russwin A-family system.
11) What is the closest interchangeable-core equivalent if a facility wants to move off rebuilding Corbin Russwin plugs?
The Corbin Russwin 564K52 is a replacement plug that keeps a CK4429 hotel lock on its existing A keyway, which means each service call is a pinning job. Facilities that want to swap cores instead of repinning typically move to an interchangeable-core platform: the BEST Peaks 1CB 150 Series interchangeable core cylinder, the BEST 1CDF drill resistant patented interchangeable core in 7-pin brass 150 Series, or the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam. The Schlage 20-057-C is the full size interchangeable core itself in the C keyway with a 643E aged bronze finish.
12) For a key-in-lever or key-in-knob lockset rather than a CK4429 hotel lock, what cylinder should be ordered?
The Corbin Russwin 564K52 plug is engineered for the CK4429 hotel lock series, so a key-in-knob or key-in-lever lockset needs a different part. The Kaba Ilco 1539 Series 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 built for Sargent locksets. In the Falcon line, the A23161-05 G is a key-in-lever cylinder for RU/T series with a 6-pin G keyway, keyed different and supplied with two cut keys.
13) What cylinder is used for a deadbolt instead of the Corbin Russwin 564K52?
The 564K52 is a hotel lock plug, not a deadbolt part. For deadbolt service, the Kaba Ilco 1549 Series 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 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
14) For an Emtek handleset, does the Corbin Russwin 564K52 work or is another cylinder needed?
The 564K52 plug is built for the Corbin Russwin CK4429 hotel lock and will not serve an Emtek handleset. Emtek applications are covered by the Emtek CY4 cylinder, sold each, or by Medeco retrofits such as the 1065244, a 5-pin rim lazy motion rim type cylinder with an Emtek tailpiece, and the 1065140, a 5-pin retrofit cylinder for Emtek handleset and deadbolt outside cylinders.
15) Is this plug suitable for anything other than hotels?
The part is specific to the CK4429 Hotel lock series, but those locks turn up well beyond hospitality. It is a commercial-rated cylinder part used for office building lock maintenance, school and healthcare cylinder work, multi-tenant residential, government buildings, and industrial cylinder rebuilds. The deciding factor is the lock, not the building type.
16) Is there a non-keyed or blank option comparable to the Corbin Russwin 564K52 plug?
The Corbin Russwin 564K52 is a functioning plug keyed to the Corbin Russwin A keyway family, offered across A1 through A24 and in 606 satin brass or 626 satin chrome. If the opening needs a cylinder that only fills the hole without operating, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter serves that purpose instead.
