Corbin Russwin 121K11 HO1 626 – Frequently Asked Questions

1) Which Corbin Russwin keyways are offered on the 121K11 cylinder plug?
Two keyway choices: HO1 and HO2, both in 626 satin chrome. HO is a restricted keyway, so blanks are controlled and you have to be set up for that keyway before the plug is any use to you. Order the one that matches the section already running on the building's keying system, because HO1 and HO2 are different sections and keys are not interchangeable between them.
2) Can I rekey an existing Corbin Russwin cylinder with this plug instead of buying a whole new cylinder?
Yes. A locksmith can pull the plug from a 1000-118 housing and drop in the 121K11 to restore or change the keying without replacing the full cylinder, which is the point of stocking it as a replacement part. You will still need the pins, springs and key blanks for the keyway you are pinning to, since only the plug is supplied.
3) Is the HO keyway on this plug restricted, and what does that mean for getting keys cut?
HO is a restricted Corbin Russwin keyway, chosen specifically to limit unauthorized key duplication under a key control program. Blanks are not sold over the counter like a standard keyway, so you or your locksmith need existing authorization on the HO section. If your facility is on an open keyway and you just want a working plug, a restricted section will complicate future key cutting.
4) I manage a building with Corbin Russwin locks on every door. Can I standardize by keeping these plugs on the shelf?
That is the usual reason to stock them. If your mortise cylinders are 1000-118 bodies on the HO section, keeping 121K11 plugs in HO1 or HO2 lets your locksmith re-core a door after a tenant turnover or a lost-key event without ordering a complete cylinder each time. Stock the keyway section that matches your existing master system, not a mix of both.
5) What finish is the 121K11 plug and does the finish matter if it is inside the cylinder?
It is supplied in 626 satin chrome. On a mortise cylinder the plug face is the visible part inside the collar or ring, so 626 is what you want when the surrounding trim is satin chrome or brushed nickel-toned hardware. The plug body itself does no wear-facing work, so the finish choice is cosmetic at the keyface.
6) Is this Corbin Russwin plug suitable for commercial buildings like schools and hospitals?
It is a commercial-grade cylinder component, and typical uses run to office buildings, schools, healthcare, government and municipal buildings, multi-tenant residential, retail, and industrial or warehouse facilities. It is a maintenance part for existing Corbin Russwin mortise cylinders in those settings rather than something for residential retrofits.
