Schlage 33-005C 626 – Frequently Asked Questions

1) Is the 33-005C a Schlage C keyway plug, and can I key it to my existing C-keyway masterkey system?
It is cut for the Schlage C keyway in a 5-pin configuration, so it takes standard C key blanks and can be pinned into an existing C-keyway system the same way any other 5-pin C cylinder would be. Pinning is done by the locksmith; the plug itself ships as the mechanical component.
2) I have Corbin Russwin cylinders, not Schlage. Is there an equivalent plug?
The Schlage 33-005C is a Schlage C keyway part and will not go into a Corbin Russwin housing. For Corbin Russwin, the equivalents are the 121K11-D2 and 121K11-L4 Grade 1 1000 Series mortise cylinder plugs, or the 253K66 for a 3000 Series rim cylinder. Match the plug to the brand and cylinder family of the lock you are servicing, not just to the pin count.
3) Is a rim cylinder plug the same thing as the Schlage 33-005C?
No. The 33-005C is a 5-pin conventional plug for Schlage deadlock and mailbox cylinders in the C keyway. A rim cylinder plug such as the Corbin Russwin 253K66, from the 3000 rim cylinder line, is sized and tailed for a rim housing mounted on the door face behind a rim exit device or night latch. They are not interchangeable - identify whether the cylinder body in hand is a rim, mortise, or deadlock cylinder before selecting a plug.
4) I need a plug for a Corbin Russwin mortise cylinder, not a Schlage. What should I be ordering?
The Schlage 33-005C is a 5-pin conventional plug cut for the Schlage C keyway and is intended for Schlage deadlock and mailbox cylinders, so it will not serve a Corbin Russwin mortise housing. For that opening, order a Corbin Russwin 121K11 series plug from the Grade 1 1000 Series mortise cylinder line, available as 121K11-D2 or 121K11-L4 plug only. Match the keyway suffix to the keying already in the building before ordering.
5) Can I just replace the plug instead of buying a whole new Schlage cylinder?
That is what this part is for. Swapping the 33-005C plug restores key function without replacing the full cylinder or the lockset, which is the usual approach when the keyway is worn or the lock needs to move to a different key system. It only works if the housing itself is sound and is not an F51 or F80 series cylinder.
6) Is this plug suitable for mailbox locks in a multi-tenant building?
Yes, mailbox lock applications are one of the two uses Schlage specifies for the 33-005C, along with deadlocks. For a property manager running a bank of tenant boxes on Schlage C keyway cylinders, it lets you rekey box by box as tenants turn over rather than buying complete cylinders each time.
7) Does a cylinder plug include the retainer or any other cylinder parts?
The 33-005C is the plug itself, the keyed barrel that turns inside the cylinder shell. Retainers are separate parts, for example Corbin Russwin sells the 219F88-8 cylinder plug retainer for its own cylinders. Reuse the retainer, cam and springs from the cylinder you are rebuilding, and plan on pins and a key blank for the keying.
8) My cylinder plug keeps backing out - do I need a new plug like the 33-005C or a different part?
If the plug itself keys and turns correctly but is not staying captive in the shell, the retaining component is the part at fault, not the plug. The Corbin Russwin 219F88-8 is a Grade 1 cylinder plug retainer for that purpose. The Schlage 33-005C is the plug itself, a 5-pin conventional plug in the C keyway for Schlage deadlock and mailbox cylinders, and is what you order when the plug is worn, damaged, or being rekeyed to a different C keyway bitting.
9) We are standardizing a building on one keyway. Does replacing plugs across Schlage and Corbin Russwin cylinders work?
Plug-level standardization only works within a manufacturer's cylinder platform. The Schlage 33-005C carries the Schlage C keyway and fits all 5-pin Schlage cylinders except the F51 and F80 series, so Schlage deadlock and mailbox cylinders can be brought onto one C-keyway system by swapping plugs. Corbin Russwin cylinders take Corbin Russwin plugs - 121K11-D2 or 121K11-L4 for 1000 Series mortise housings, 253K66 for 3000 rim - and stay on Corbin Russwin keyways. A mixed building either keeps two key systems or gets its cylinders replaced wholesale on one platform.
10) Is the Schlage 33-005C rated for commercial use or is it a residential part?
It is specified for commercial door hardware use, and the intended jobs are commercial deadlock and mailbox servicing in offices, schools, government and institutional facilities as well as multi-tenant residential property maintenance.
11) Does the finish choice on the 33-005C matter if I am comparing it to other plugs?
The Schlage 33-005C comes in 606 satin brass and 626 satin chrome, so the visible plug face can be matched to the trim on the door or mailbox bank. Comparable plugs such as the Corbin Russwin 121K11-D2 and 253K66 are ordered as plug-only components in their own finish ranges. If the plug face shows below an escutcheon or a mailbox door, pick the 33-005C finish that matches the surrounding hardware rather than whichever is on the shelf.
