Corbin Russwin 253K66 L1 626 – Frequently Asked Questions

1) Can I rekey a Corbin Russwin rim cylinder by swapping just the plug instead of replacing the whole cylinder?
That's exactly what this part is for. The 253K66 plug lets a locksmith restore or change a 3000 Series rim cylinder without pulling and replacing the entire assembly, which keeps the existing housing, cam and mounting in the door. It is sold as a replacement component, so the housing has to be a compatible Corbin Russwin 3000 Series rim cylinder.
2) Will the 253K66 L plug fit a Schlage or BEST rim cylinder?
No. It is cut to Corbin Russwin 3000 Series rim cylinder tolerances and the L keyway profile, so it only serves Corbin Russwin housings. If the door has a Schlage rim cylinder, replace it with a Schlage part such as the 20-021 (vertical tailpiece cam) or 20-022 (horizontal tailpiece cam). On a BEST small-format interchangeable core opening you pull the core instead, using something like the BEST 1C Series 5-pin core.
3) If I need a complete rim cylinder rather than just a plug, what should I order instead of the Corbin Russwin 253K66?
The Corbin Russwin 253K66 L1 is a 3000 Series rim cylinder plug - a replacement component for an existing rim cylinder assembly, not a full cylinder. If the whole cylinder needs replacing, the Schlage Commercial 20-021 is a complete 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the Schlage Commercial 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam and two keys. Choose the cam orientation your exit device or rim lock requires.
4) We want to move to interchangeable cores instead of rekeying rim cylinder plugs - what are the options?
The Corbin Russwin 253K66 is a fixed 3000 Series rim cylinder plug, so rekeying means pinning the plug itself. If you want to swap cores in the field instead, the Schlage Commercial 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam and two keys, and the Schlage 20-057-C is an FSIC core in the C keyway with a 643E aged bronze finish. On the small format side, the BEST 1CB is a 150 Series interchangeable core cylinder and the BEST 1CDF is a drill resistant patented 7-pin brass interchangeable core in the same 150 Series family.
5) What cylinder do I use if the lock is a mortise body rather than a rim device?
The Corbin Russwin 253K66 plug serves 3000 Series rim cylinders, which sit behind rim-prepped exit devices and rim locks. For a mortise prep, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security in the 4036 Series, rated for doors 1/2 inch minimum thickness, and the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway.
6) I need a keyed cylinder for a key-in-lever or deadbolt, not a rim device. What fits?
The Corbin Russwin 253K66 L1 is a rim cylinder plug and will not serve a key-in-lever or bored deadbolt. For those preps, the Kaba Ilco 1539 is a universal key-in-knob and lever cylinder, the 1549 is a key-in-deadbolt cylinder, the 1579 is a knob and lever cylinder 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 the RU/T series with a 6-pin G keyway, keyed different with two cut keys.
7) What finishes does the 253K66 rim cylinder plug come in?
Two: 606 satin brass and 626 satin chrome. Both keyway and finish are ordered together, and all three L keyways (L1, L2, L3) are offered in either finish. Match the plug face to the existing cylinder ring and exit device trim so the repaired opening still looks like the rest of the doors.
8) I need a rim cylinder for an exit device but my building isn't keyed Corbin Russwin. What should I order?
A plug like the 253K66 only helps if the housing is already Corbin Russwin 3000 Series. For an exit device on another key system, order a complete rim cylinder in your keyway: Schlage's 20-021 and 20-022 are 6-pin rim cylinders supplied with two keys and differ only in tailpiece cam orientation (vertical versus horizontal), and the 20-057 is the full-size interchangeable core version with a convertible tailpiece cam if you run FSIC.
9) Does the L keyway on the 253K66 give me restricted key duplication?
The L keyway is a Corbin Russwin keyway profile used for controlled key duplication and organized key system management, so keys can only be cut on L-profile blanks. It keeps the plug inside your existing key hierarchy rather than opening it up to generic blanks. Specify L1, L2 or L3 to match the level your system is already set up on.
10) Is the Corbin Russwin 253K66 the same thing as a BEST 1C core?
No. The 253K66 L1 is a Corbin Russwin 3000 Series rim cylinder plug built to fit inside a compatible Corbin Russwin rim cylinder shell, supplied with L keyway family profiles in L1, L2 and L3. The BEST 1C5 is a standard 5-pin interchangeable core from BEST's standard and premium core line, which drops into BEST small format housings. They are different platforms and do not interchange.
11) The opening needs a rim cylinder but no key function - what is the alternative?
The Corbin Russwin 253K66 L1 is a keyed plug carrying the L keyway for controlled duplication. If the position is only a filler or a matching non-functioning cylinder, the BEST 12E Series dummy rim cylinder measures 1-5/32 inch in diameter and provides the appearance without key operation.
12) For an Adams Rite MS1847 narrow stile deadlock, can I use the Corbin Russwin 253K66 plug?
The 253K66 L1 plug belongs to the Corbin Russwin 3000 Series rim cylinder platform and is not the part for an Adams Rite narrow stile deadlock. The Adams Rite 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch systems, and the 4025 is a five pin tumbler cylinder pull using through-screws for the same MS1847 deadlock. For a wood door application, the Adams Rite 4026 five pin tumbler cylinder pull is made for the 5017 wood door deadlock and deadlatch.
13) Is this cylinder plug suitable for a high-traffic commercial building or is it a residential part?
Commercial. The 253K66 is a commercial-grade cylinder component built to Corbin Russwin's standards for high-use door hardware, and it's the sort of service part used across office buildings, schools, healthcare, retail, government facilities and multi-tenant residential properties where an in-house locksmith maintains a keyed system.
14) How do I match a replacement cylinder plug finish when the rest of the hardware is brass versus chrome?
The Corbin Russwin 253K66 plug is offered in 606 satin brass and 626 satin chrome, each available with L1, L2 or L3 keyways, so you can match the existing trim without changing the key system. If you are replacing a whole cylinder in a darker trim scheme, the Schlage 20-057-C full size interchangeable core is furnished in 643E aged bronze with the C keyway.
