Medeco 205005T-26-DLT – Frequently Asked Questions

1) Will the Medeco 205005 cylinder fit a Corbin Russwin CK 4200 lockset?
That is exactly what it is built for. The Medeco 205005 is a 6-pin key-in-knob/lever retrofit cylinder made for the Corbin Russwin CK 4200 New Style lockset. It drops into the existing lock, so you upgrade the key control without replacing the whole lockset. If your CK 4200 is the older style rather than New Style, this is not the right cylinder.
2) Do I order Medeco Biaxial or M3 for a 205005 cylinder?
Both keyways are offered on the 205005, and the right one is whichever your existing Medeco system is keyed to. Order Biaxial if you are extending an existing Biaxial master key system, M3 if your facility runs M3. Mixing the two in one system will not work, so match what the rest of your building already uses before you commit.
3) What is the difference between pinned, sub-assembled, and sub-assembled no slider on a Medeco cylinder order?
Those are the three pinning states the 205005 ships in. Pinned means it comes keyed and ready to install. Sub-assembled is supplied for a locksmith or in-house shop to pin to your own system. Sub-assembled, no slider leaves the slider out as well, for shops building the cylinder to a specific Medeco system in the field. If you do not have a keying shop, order it pinned.
4) Is the Medeco 205005 rated for high-security commercial use?
It is. The Medeco M4 key-in-knob cylinders are UL 437 Listed for drill and pick resistance, and the 205005 meets ANSI A156.30 Level A for patent-protected key control and physical strength plus ANSI A156.5 Grade 1 for heavy-use applications. That combination is what specifiers in healthcare, education, and government facilities typically write into a key control program.
5) What else can a Medeco 205005 retrofit cylinder go into besides a knob lock?
Beyond knob-type cylindrical locksets, the 205005 is designed to retrofit lever-type cylindrical locksets, padlocks, and bored-type auxiliary deadlatches and deadlocks. Medeco builds over 100 cylinder designs and tailpiece configurations, so the tailpiece is what determines which host hardware a given cylinder serves. This one is configured for the Corbin Russwin CK 4200 New Style.
6) Can keys for this Medeco cylinder be copied at a hardware store?
No. The 205005 uses Medeco's patent-protected key control technology, which restricts unauthorized duplication. Keys are cut through authorized channels against your system records, which is the point of the upgrade for buildings running restricted access programs across multiple tenants or departments.
7) Why choose a 6-pin Medeco cylinder over a 5-pin for a master keyed building?
The 205005 is a 6-pin cylinder, and the extra chamber gives more key combinations and more pick resistance than a 5-pin. In a facility running a master key system across many doors, that extra chamber is what keeps the system expandable as you add openings without running out of usable combinations.
8) What finishes does the Medeco 205005 cylinder come in to match existing knobs and levers?
Thirteen finish choices are available: 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 a property manager standardizing a building, 626 Satin Chrome and 613 Oil-Rubbed Bronze are the usual matches to existing commercial lever trim.
9) What is the Medeco 205005 made of, and will it hold up in a high-traffic building?
All cylinder components are machined brass. Paired with the ANSI A156.5 Grade 1 rating, which covers heavy-use commercial service, it is built for openings that see constant daily cycling such as school corridors, hospital wings, and warehouse entries.
