Schlage 33-058FG 626 – Frequently Asked Questions

1) Will the Schlage 33-058FG cylinder plug work with my existing Schlage keys?
Only if your keys are cut on the FG keyway. The 33-058FG is machined for the FG keyway profile, so a key on any other Schlage keyway (C, E, L, and so on) will not enter it. Check the keyway stamp on your existing key bow or core before ordering, because the plug cannot be re-milled to another keyway.
2) Is this a complete interchangeable core or just the plug?
Just the plug. The 33-058FG is the rotating plug portion that goes inside a Schlage full size interchangeable core, not a finished core you can drop into a lock. If you need a working core you also need the core shell, pins, springs, and a control key to operate the system. Order the plug when you are rebuilding or repinning cores at the bench.
3) Can I use this 6-pin plug in a 7-pin Schlage FSIC core?
No. The 33-058FG is a standard 6-pin FSIC plug and it is drilled for six chambers. Schlage 7-pin Everest and similar systems use a different plug drilled for seven. Match the pin count of the core shell and the bitting on your existing keys, otherwise the plug will not key up correctly.
4) I need a plug for a Corbin Russwin cylinder, not Schlage. Is this the right part?
No, the two are not interchangeable. Schlage FSIC and Corbin Russwin cylinders use different plug geometry and keyways. For Corbin Russwin, the 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs, and the 253K66 is a 3000 Series rim cylinder plug. Pick by the cylinder body you are rebuilding, mortise or rim, and by the keyway that matches your existing keys.
5) What is the difference between the Schlage 33-058FG cylinder plug and the Corbin Russwin 253K66 rim cylinder plug?
They serve different cylinder platforms. The Schlage 33-058FG is a standard 6-pin full size interchangeable core (FSIC) cylinder plug cut for the FG keyway, so it goes into an FSIC core that can be pulled and swapped without taking the lock off the door. The Corbin Russwin 253K66 is a 3000 series rim cylinder plug, meaning it belongs to a rim cylinder body of the type used behind exit devices. A rim plug will not seat in a Schlage FSIC core, and the keyways are different systems, so the two are not interchangeable in either direction. Choose by the cylinder body already in the door: FSIC core on Schlage keying, use the 33-058FG; Corbin Russwin 3000 rim cylinder, use the 253K66.
6) I need a plug for a mortise cylinder, not an interchangeable core - what should I order instead of the Schlage 33-058FG?
The 33-058FG is a full size interchangeable core plug, so it is the wrong part for a conventional mortise cylinder. For mortise work, Corbin Russwin offers plug-only parts in the 1000 series: the 121K11-D2 and the 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs supplied as the plug only, differing in the keyway designation (D2 versus L4). Match the suffix to the keyway your existing Corbin Russwin system is keyed to. Use the Schlage 33-058FG only where the housing is a Schlage FSIC core on the FG keyway.
7) Why choose FSIC over a conventional cylinder for a building I have to rekey often?
With a full size interchangeable core, a control key pulls the core out of the lock and a replacement drops in, so you rekey an opening in seconds without removing the lockset or the door trim. A conventional cylinder has to be pulled and repinned in place. For schools, hospitals, offices, and multi-tenant buildings with tenant turnover, FSIC is the system that keeps a locksmith from disassembling hardware on every change, and the 33-058FG is the plug that gets repinned at the bench.
8) Is a cylinder plug retainer the same thing as a cylinder plug?
No. A plug is the keyed rotating barrel that the pins sit in. A retainer is the small clip or cap that holds the plug in the cylinder body, like the Corbin Russwin 219F88-8 Grade 1 cylinder plug retainer. If your problem is a plug that is loose or backing out, you want a retainer, not a new plug such as the Schlage 33-058FG.
9) Our facility is standardizing on interchangeable core rekeying - do any of the Corbin Russwin cylinder plugs give us that, or do we need the Schlage 33-058FG?
For interchangeable core rekeying, the Schlage 33-058FG is the part that supports it: it is a full size interchangeable core plug, and FSIC systems let maintenance swap cores without removing the lock from the door, which is why schools, hospitals and multi-tenant properties standardize on them. The Corbin Russwin plugs in the same family of parts serve conventional cylinder formats instead - the 121K11-D2 and 121K11-L4 are 1000 series mortise cylinder plugs and the 253K66 is a 3000 rim cylinder plug. Those are the right parts for mortise and rim cylinder bodies, but they do not deliver core-swap rekeying.
10) What is the difference between the Corbin Russwin 121K11-D2 and 121K11-L4 if I am cross-shopping against the Schlage 33-058FG?
Both Corbin Russwin parts are Grade 1 1000 Series mortise cylinder plugs supplied as the plug only; the D2 and L4 suffixes identify different keyway sections within the Corbin Russwin system, so the choice between them is decided by how your building is keyed, not by the hardware they fit. The Schlage 33-058FG sits in a separate system entirely - a standard 6-pin FSIC plug on the Schlage FG keyway in satin chrome. A Corbin Russwin keyed building takes the 121K11 plugs; a Schlage FSIC building takes the 33-058FG.
11) Is this plug rated for commercial use or is it a residential part?
Commercial. Schlage catalogs the 33-058FG under its commercial parts program as a replacement component for FSIC lock systems in offices, schools, healthcare, government, retail, and industrial buildings. It is not a residential-grade item.
