Medeco 2020073T-26-DLT – Frequently Asked Questions

1) Will the Medeco 2020073 cylinder fit my Schlage ND or AL Series lever locks?
Yes. The 2020073 is a key-in-knob/lever retrofit cylinder built to drop into Schlage ND and AL Series cylindrical locksets, along with Arrow MK Series, the Falcon inside cylinder, LSDA 100 B Knob, and Yale YMCL100 and 200. You swap the cylinder only, the lockset stays in the door, so there is no new prep and no chassis change.
2) Can I put Medeco high security keys on my existing knob and lever locks without replacing the locksets?
That is exactly what the 2020073 does. It is a 6-pin Medeco cylinder that replaces the factory key-in-knob/lever cylinder in Arrow MK, Falcon, LSDA 100 B Knob, Schlage ND and AL, and Yale YMCL100/200 locksets. The existing chassis, latch, strike and trim all stay. For a property manager or facility with a mix of those brands already hanging, it means one Medeco key system across the building without pulling hardware off the doors.
3) Do I order the Medeco 2020073 in Biaxial or M3?
Both keyway technologies are offered, and the deciding factor is what key system you already run. If your facility is keyed in Medeco Biaxial, order Biaxial so the new cylinder keys into the existing system. If you are on M3, order M3. Starting fresh, M3 is the newer platform and is the one the UL437 and ANSI A156.30 Level A certifications are stated for on the Medeco M-series cylinders. Mixing the two on one master key system is not something you want to do by accident, so match what your keying record says.
4) Is the Medeco 2020073 cylinder UL437 listed and ANSI Grade 1?
Yes on both counts. Medeco M4 key-in-knob cylinders are UL437 listed for drill and pick resistance, and the 2020073 carries ANSI/BHMA A156.30 Level A for patent-protected key control and physical strength plus ANSI/BHMA A156.5 Grade 1 for heavy-use quality. That combination is what a school district, hospital, or government facility spec usually calls out when it asks for a high security cylinder rather than just a keyed lock.
5) Does the Medeco 2020073 stop tenants from copying keys at the hardware store?
That is the main reason to buy it. The 2020073 uses Medeco utility patent-pending key control, so blanks are restricted and a hardware store or kiosk cannot cut a copy. It is certified to ANSI A156.30 Level A, the level that covers patent-protected key control. For multi-tenant residential and commercial office buildings, that removes the unauthorized duplicate problem without rekeying the whole building to a new lockset line.
6) I have a mix of Schlage, Yale and Arrow knobs in my building. Can one Medeco key system cover all of them?
Across those specific lines, yes, through this one part. The 2020073 retrofits Arrow MK Series, the Falcon inside cylinder, LSDA 100 B Knob, Schlage ND and AL Series, and Yale YMCL100 and 200, so all of those openings can take the same Medeco keyway and sit under the same master. Medeco builds over 100 cylinder designs and tailpiece configurations, so openings outside that list, mortise or rim for example, are usually covered by a different Medeco cylinder rather than a lockset swap.
7) What is the difference between Pinned, Sub-Assembled, and Sub-Assembled No Slider on a Medeco cylinder order?
Three build states. Pinned ships keyed and ready to install, which is what you want if you are not a locksmith and are not cutting keys yourself. Sub-Assembled ships without the pinning done, for a locksmith or dealer combinating it into an existing master key system in the shop. Sub-Assembled, No Slider is the same unpinned build with the slider left out, for shops setting up the Biaxial or M3 sidebar components themselves. If you do not have a Medeco keying setup and key blanks on hand, order Pinned.
8) Can I match the Medeco retrofit cylinder to the oil-rubbed bronze levers already on my doors?
Yes. The 2020073 comes in 13 finish options: 20 Antique Nickel, 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, 622 Flat Black, 624 Dark Bronze, 625 Bright Chrome, and 626 Satin Chrome. For oil-rubbed bronze trim, 613 is the match. Most commercial openings running satin chrome levers take 626.
9) Will the Medeco 2020073 work in a Schlage B-series deadbolt or a mortise lock?
No. The 2020073 is a key-in-knob/lever cylinder, which is the cylinder that sits in the knob or lever of a cylindrical lockset. Deadbolts, mortise locks, and rim exit devices use different cylinder formats and a different tailpiece or cam. Medeco makes cylinders for those applications, but you need the one built for that format, not this one.
10) Is a 6-pin Medeco cylinder enough for a large master key system?
Six pins is the deeper of the two common cylindrical configurations and gives you more usable change key combinations under a master, which matters when you are keying a whole campus or a multi-building portfolio rather than a handful of doors. The 2020073 is a 6-pin build. Combined with the Biaxial or M3 sidebar, the practical capacity is considerably larger than a standard 5-pin conventional cylinder of the same size.
11) Is this Medeco cylinder rated for commercial traffic or is it a residential part?
Commercial. The 2020073 is built from machined brass components and certified to ANSI A156.5 Grade 1, the heavy-use grade, which is what puts it in schools, hospitals, warehouses, retail, and government buildings rather than houses. A residential-grade cylinder would not carry Grade 1 or the UL437 drill and pick listing.
