Medeco 20211730T-26-DLT – Frequently Asked Questions

1) Will the Medeco 20211730 cylinder fit a Corbin Russwin CL3300 lever lockset?
Yes. The Medeco 20211730 is a 6-pin key-in-knob/lever retrofit cylinder built to drop into Corbin Russwin 800, CL3300, CL3400, CL3500 and CL3600 series locksets. You keep the existing lockset and chassis and swap only the cylinder, so an existing knob or lever set can be brought onto a Medeco high-security key system without replacing the lock.
2) Do I have to choose between Biaxial and M3 when ordering this Medeco cylinder?
Yes, keyway technology is an order choice: the 20211730 cylinder is offered in Medeco Biaxial and in M3. Pick the one that matches the key system already in the building, because the two are not interchangeable keyways. If you are starting a new system, M3 is the current-generation platform and is the version the ANSI A156.30 Level A and A156.5 Grade 1 certifications are cited for.
3) What is the difference between Pinned, Sub-Assembled, and Sub-Assembled No Slider on this cylinder?
Those are the three build states the 20211730 ships in. Pinned means the cylinder comes keyed and ready to install. Sub-Assembled is supplied for a locksmith or end user with a Medeco key machine and pinning kit to key on site into an existing system. Sub-Assembled, No Slider leaves the slider out as well, for shops that pin and assemble the complete cylinder themselves. Order Pinned unless you have the pinning capability and the key records in house.
4) Is this Medeco key-in-knob cylinder actually rated for high security, or just marketed that way?
The Medeco key-in-knob/lever cylinder line carries UL 437 listing for drill and pick resistance on M4, ANSI/BHMA A156.30 Level A for patent-protected key control and physical strength, and ANSI/BHMA A156.5 Grade 1 for heavy-use applications. For a spec writer or an institutional buyer, those are the three line items usually required on a high-security cylinder submittal.
5) Can my tenants get copies of these keys cut at a hardware store?
No. Medeco key control on this cylinder is patent protected, which restricts key blank distribution and blocks over-the-counter duplication. For a property manager that is the point of the upgrade: keys come only through authorized channels against your records, so a departing tenant or contractor cannot quietly make copies.
6) Do I need to replace the whole Corbin Russwin lockset to upgrade to Medeco?
No, and that is the reason to buy this part. The 20211730 drops into the existing Corbin Russwin 800 or CL3300 through CL3600 lockset, so labor is a cylinder swap rather than a door prep and full lockset change. Medeco builds over 100 cylinder and tailpiece configurations, so other hardware brands on the same property can usually be brought onto the same key system the same way.
7) Can I match this cylinder to the finish of the levers already on my doors?
Thirteen finishes are offered on the 20211730: 605 Bright Brass, 606 Satin Brass, 609 Antique Brass, 611 Bright Bronze, 612 Satin Bronze, 613 Dark Bronze Oil-Rubbed, 618 Bright Nickel, 619 Satin Nickel, 20 Antique Nickel, 622 Flat Black, 624 Dark Bronze, 625 Bright Chrome and 626 Satin Chrome. For most commercial openings the lever is 626 Satin Chrome or 613 oil-rubbed bronze, so match the cylinder face to that number.
8) Is the 20211730 only for knob and lever locks, or will it work in a padlock or deadlatch?
Beyond knob-type and lever-type cylindrical locksets, this cylinder is intended to retrofit padlocks and bored-type auxiliary deadlatches and deadlocks. That is what lets a property with mixed hardware bring several device types onto one Medeco key, provided the host device takes a key-in-knob style cylinder.
9) Why choose a 6-pin cylinder instead of a 5-pin for a commercial masterkey system?
The 20211730 is a 6-pin cylinder. The sixth chamber gives a masterkeying system substantially more usable key changes, which matters when one facility needs grand master, master and change keys without duplicating combinations, and it adds a pin stack for a picker to defeat. On a small single-door job a 5-pin is adequate; on a campus or multi-tenant building with expansion planned, 6-pin is the one to standardize on.
10) Is this a commercial cylinder or is it suitable for a house?
It is classified commercial. Machined brass components and ANSI A156.5 Grade 1 certification for heavy-use applications point it at office buildings, schools, healthcare, government facilities, retail, warehouses and multi-tenant residential where key control is controlled by management rather than the occupant.
