Medeco 20200V0T-26-DLT – Frequently Asked Questions

1) Will the Medeco 20200V0 cylinder fit a Dorma CL870 lever lockset?
Yes. The 20200V0 is built as a retrofit key-in-knob/lever cylinder for the Dorma CL860, CL870, CL872, CL873 and CL877 lever locksets, and the matching CK860, CK870, CK872, CK873 and CK877 knob locksets. It drops into the existing lockset, so the knob or lever, chassis and door prep all stay as they are.
2) I have Marks 195 knob locks in my building. Is there a Medeco high-security cylinder that fits them?
The 20200V0 covers the Marks 110, 170, 180, 190, 195 and 295 Series, plus Embassy Vestibule hardware. One cylinder part number handles that whole spread, which is what you want if a property has a mix of Marks generations on different openings and you are standardizing key control across all of them.
3) Can I upgrade to Medeco without buying new locksets for the whole building?
That is the point of the 20200V0. It swaps the cylinder inside knob-type and lever-type cylindrical locksets you already have (Dorma CL/CK860-877, Marks 110 through 295, Embassy Vestibule) and leaves the lockset, trim and door prep alone. For a property manager or MRO buyer, that turns a lockset replacement project into a cylinder change on each door.
4) Should I order the 20200V0 in Biaxial or M3 keyway?
Order whichever platform your existing Medeco system is already on. The 20200V0 is offered in Biaxial and in M3, and those are different key platforms, so keys will not cross between them. If you are keying these into an existing master key system, match the platform on your current cylinders; if this is a brand new system, pick one and keep every opening on it.
5) Does the Medeco 20200V0 meet Grade 1 requirements for a commercial spec?
The certifications listed for the Medeco M4 platform are UL 437 for drill and pick resistance, ANSI/BHMA A156.30 Level A for patent-protected key control and physical strength, and ANSI/BHMA A156.5 Grade 1 for heavy-use commercial quality. That is the combination institutional and government specs normally call for when they ask for a high-security cylinder rather than a conventional one.
6) My locksets are Schlage and Sargent, not Dorma or Marks. Is the 20200V0 the right Medeco cylinder?
No. The 20200V0 is cut for Dorma CL/CK860-877, Marks 110 through 295, and Embassy Vestibule hardware, and the tailpiece and cylinder design are specific to those. Medeco builds over 100 different cylinder designs and tailpiece configurations across the retrofit line, so there is a different part number for other lockset brands. Identify the lockset series on the door first, then match the cylinder to it.
7) What is the difference between Pinned and Sub-Assembled when ordering a Medeco 20200V0?
Pinned means the cylinder ships built to your keying, ready to install. Sub-Assembled means it comes as an unpinned assembly for a locksmith or dealer to pin into their own restricted system, and there is also a Sub-Assembled, No Slider version supplied without the slider component. Locksmiths running their own keying bench usually take the sub-assembled options; a property manager or facility buyer wants Pinned.
8) Do I need to give keying information when I order this cylinder?
If you take the Pinned version, yes, it has to be pinned to a keyway and a key system, and the 20200V0 is available on either the Biaxial or the M3 platform. Medeco keyways are restricted, so key control sits with the authorized dealer for your system. If you are pinning in-house, order one of the sub-assembled versions instead.
9) Why choose a 6-pin cylinder over a standard 5-pin for a commercial door?
The 20200V0 is a 6-pin key-in-knob/lever cylinder, and the extra chamber both raises pick resistance and gives you more room to build a master key system without running out of usable key changes. On a multi-tenant or campus property where one grand master has to sit above several building masters, that additional depth is what keeps the system expandable.
10) Can I get this Medeco retrofit cylinder in a finish that matches my existing oil-rubbed bronze levers?
Thirteen finishes are offered: 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 oil-rubbed bronze trim, 613 is the match.
11) Will this cylinder hold up in a high-traffic building or a damp environment?
Cylinder components are precision-machined brass, which is what gives it corrosion resistance in demanding commercial settings, and it is rated for heavy-use commercial environments under ANSI/BHMA A156.5 Grade 1. Typical uses run to schools, hospitals, warehouses, government buildings and multi-tenant residential.
