Medeco MED-20200S1T-06-DLT – Frequently Asked Questions

1) Will a Medeco 20200S1 cylinder fit my Schlage ND series levers?
Yes. The 20200S1 6-pin key-in-knob/lever cylinder retrofits Schlage A, AL, C, D, ND and Olympiad lever designs, so an ND series cylindrical lever takes it directly. It also covers K200, L100, LX100, L200 and LX200 lever platforms. You keep the existing lockset and swap only the cylinder, which is the point of the part.
2) Can I use a Medeco 20200S1 on cabinet locks, not just door levers?
On Olympus 700LCM and 800LCM key-retaining cabinet locks, yes. Those are named as compatible hardware for the 20200S1 alongside the lever platforms, which makes it usable for tool cribs, records cabinets and similar secured storage on the same key system as the doors. It also fits cylindrical locksets, padlocks and bored-type auxiliary deadlatches and deadlocks.
3) What is the difference between the Biaxial and M3 versions of the Medeco 20200S1?
Those are the two keyway and technology platforms the 20200S1 is offered on, and they are not interchangeable keying systems. Order the one that matches the Medeco system already in your building, because a Biaxial key will not operate an M3 cylinder and the reverse is equally true. If you are starting a new key system rather than extending one, that choice is set by whichever platform your locksmith or Medeco dealer holds the key control records for.
4) Do I order the Medeco 20200S1 pinned, or sub-assembled?
Three build states are offered: Pinned, Sub-Assembled, and Sub-Assembled No Slider. Pinned arrives keyed and ready to install, which is what a property manager or facilities crew wants. The sub-assembled options ship without the pinning done so a locksmith can key them into an existing master system on the bench. The No Slider variant leaves the slider out for shops that stock and set their own.
5) Is the Medeco 20200S1 cylinder rated for drill and pick attack?
UL 437 listed for drill and pick resistance as part of the Medeco M4 family. It also carries 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. Those three are the set an institutional spec normally calls out for a high-security cylinder retrofit.
6) Can I stop tenants copying keys with a Medeco 20200S1?
Key control is the reason this cylinder exists. The 20200S1 uses Medeco's utility patent-pending key control to block unauthorized duplication, and it is certified to ANSI A156.30 Level A for patent-protected key control. Practically, blanks are restricted and cuts come through an authorized channel, so a resident or contractor cannot walk into a hardware store and copy the key.
7) Is a 6-pin retrofit cylinder enough, or do I need to replace the whole lockset?
If the lockset body and lever are sound, the cylinder is the only piece that needs to change. The 20200S1 is a 6-pin drop-in for the lever platforms it covers, and Medeco publishes over 100 cylinder and tailpiece configurations across the line, which is what makes the retrofit route work instead of buying new hardware. Replace the full lockset only when the chassis is worn, the function is wrong, or the lever itself has failed. On a large door count, the cylinder swap is the difference between a one-trade job and a hardware replacement program.
8) What finishes does the Medeco 20200S1 retrofit cylinder come in?
Thirteen finishes, so the cylinder face can be matched to the lever it goes into: 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 buildings the match is 626 Satin Chrome or 613, since those are what the existing Schlage lever trim usually is.
9) What is the Medeco 20200S1 made of, and will it hold up in a school or hospital corridor?
Machined brass components throughout, and the cylinder is certified to ANSI A156.5 Grade 1, the heavy-use grade. That is the combination specified for corridor doors in schools, healthcare and government facilities where the key sees daily traffic. It is a commercial-duty part, not a residential one.
10) Can I put Medeco 20200S1 cylinders on some doors and keep standard cylinders on the rest?
You can, and it is the usual way a building phases in. Because the 20200S1 drops into the existing K200, L100, LX100, L200, LX200 and Schlage A, AL, C, D, ND and Olympiad levers, you can start with exterior and sensitive rooms and work inward as budget allows. The one thing to plan for: the Medeco cylinders operate on a separate high-security key system, so master keying across both the new and the old cylinders needs to be laid out before the first order rather than after.
11) Does the Medeco 20200S1 come with the tailpiece for my lockset?
Tailpiece configuration is what makes a key-in-knob cylinder specific to a lock, and Medeco builds over 100 cylinder and tailpiece configurations across the range. The 20200S1 is the key-in-knob/lever cylinder for the K200, L100, LX100, L200, LX200 and Schlage A, AL, C, D, ND and Olympiad platforms, so identify the exact lockset series you are retrofitting when you order and the correct configuration goes with it.
