Medeco 20200V1T-26-DLT – Frequently Asked Questions

1) Will the Medeco 20200V1 cylinder fit my Alarm Lock or Marks lever lockset?
The 20200V1 is a key-in-knob/lever retrofit cylinder built to drop into knob-type and lever-type cylindrical locksets from Alarm Lock, Cal-Royal, Dorma, Kaba-Mas, Marks, and Medeco. It also retrofits padlocks and bored-type auxiliary deadlatches and deadlocks. You keep the existing lockset and swap only the cylinder, so the door prep and the lock body stay as they are. What decides the fit on your specific lock is the tailpiece, and Medeco publishes over 100 cylinder and tailpiece configurations for exactly that reason.
2) Is the Medeco 20200V1 key-in-knob cylinder UL 437 listed and ANSI Grade 1?
Both. Medeco M4 key-in-knob cylinders are UL 437 listed for drill and pick resistance, and the cylinder is certified to ANSI/BHMA A156.30 Level A for patent-protected key control and physical strength, plus ANSI/BHMA A156.5 Grade 1 for heavy-use applications. For a spec writer on a government, healthcare, or school job, that combination is what lets a retrofit cylinder hold the same security line as the original lockset without replacing the lockset.
3) What is the difference between the Biaxial and M3 keyway options on a Medeco 20200V1 cylinder?
Technology is the first thing to settle, because it decides which keys work. The 20200V1 is offered in Medeco Biaxial and in M3. If your facility is already keyed in one of those systems, order to match it: a cylinder in the other technology will not accept your existing keys and will start a second key system in the same building. Buying to match the system you already run is what keeps one key working across the openings.
4) What does Pinned versus Sub-Assembled mean when ordering a Medeco 20200V1 cylinder?
That option decides how much work you do at the bench. Pinned means the cylinder arrives pinned to your key system. Sub-Assembled ships for a locksmith to pin into an existing system, and there is a Sub-Assembled, No Slider version as well. If you are a property manager or MRO buyer without a keying shop, order Pinned. If you are a locksmith maintaining a masterkey system, the sub-assembled options are what you pin yourself.
5) Can I stop tenants copying keys by just changing the cylinder instead of replacing every lockset?
That is what this part is for. Swapping in a 20200V1 gives you Medeco's utility patent-pending key control, which restricts unauthorized key duplication, without touching the lockset, the door prep, or the trim. For a landlord or a property manager with a fleet of doors, it is a cylinder-level upgrade to a keyed system rather than a hardware replacement project, and the retrofit range across knob locks, lever locks, padlocks, and bored auxiliary deadlocks means one key system can cover mixed hardware.
6) I have a mortise lock, not a knob or lever lock. Is this the right Medeco cylinder?
No. The 20200V1 is a key-in-knob/lever cylinder, which is the round cylinder that sits in the knob or lever of a bored cylindrical lockset. A mortise lock takes a threaded mortise cylinder with a cam, and a rim exit device takes a rim cylinder. Medeco builds those in the same Biaxial and M3 keyways, so you can stay on one key system across all three, but the body style has to match the lock you are working on.
7) How many pins does the Medeco 20200V1 cylinder have, and can it be masterkeyed?
Six-pin. The 6-pin tumbler configuration is what gives the cylinder the depth of combination a commercial masterkey system needs, and it is the standard chamber count for key-in-knob and lever cylinders on commercial locksets. Order it sub-assembled if you intend to pin it into an existing master system yourself.
8) Can I get a Medeco key-in-knob cylinder in oil rubbed bronze or satin chrome to match my existing hardware?
Thirteen finishes are offered on the 20200V1, so matching an existing set of levers is normally straightforward: 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. On most commercial openings the lockset is 626 satin chrome or 613 oil-rubbed bronze, and the cylinder face is the visible part, so match the lockset rather than the door.
9) Is the Medeco 20200V1 cylinder rated for commercial traffic, and what is it made of?
It is a commercial-duty part, built from machined brass components and certified to ANSI A156.5 Grade 1, which is the heavy-use tier. Typical placements are office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential, and municipal buildings. On a low-traffic residential interior door it is more cylinder than the opening needs.
