Medeco 20200F1T-26-DLT – Frequently Asked Questions

1) Will the Medeco 20200F1 cylinder fit my Falcon lever locks?
The 20200F1 is built as a drop-in replacement for Falcon B, LY, X, S and T series locksets, both knob-type and lever-type cylindrical locks. It also covers padlocks and bored-type auxiliary deadlatches and deadlocks. If your Falcon hardware is in one of those series, you swap the cylinder rather than replacing the whole lockset, so the existing door prep, latch and trim stay as they are.
2) Is the Medeco 20200F1 a high security cylinder that resists drilling and picking?
Drill and pick resistance is verified: Medeco M4 key-in-knob cylinders carry a UL 437 listing. The 20200F1 is a 6-pin cylinder machined from brass, and it meets ANSI A156.30 Level A for patent-protected key control and physical strength plus ANSI A156.5 Grade 1 for heavy-use commercial cycling. That combination is what a facility asks for when the opening is an exterior or tenant door taking real traffic.
3) What is the difference between the Biaxial and M3 versions of the Medeco 20200F1?
Both keyways are offered on the 20200F1 key-in-knob cylinder, and the one you order has to match the key system the building already runs on. Biaxial and M3 are separate Medeco platforms, so keys are not interchangeable between them. Pick the platform your existing Medeco keys are cut on; if you are starting a new key system on this building, pick one and stay with it across the openings you plan to key alike.
4) What does Pinned versus Sub-Assembled mean when ordering a Medeco key-in-knob cylinder?
Three build states are offered on the 20200F1: Pinned, Sub-Assembled, and Sub-Assembled No Slider. Pinned ships built to a key code, which is what a property manager or facility wants when the cylinder goes straight onto the door. The sub-assembled versions are for a locksmith or dealer who pins to their own system in the shop; the No Slider option leaves out the slider for shops assembling Biaxial or M3 cylinders themselves. If nobody on your side pins cylinders, order Pinned.
5) Can I stop tenants from copying keys on my Falcon locks without changing all the locksets?
That is what this cylinder is for. Medeco's key control here is patent-protected, which restricts unauthorized duplication at the key blank level, and the 20200F1 drops into Falcon B, LY, X, S and T series hardware. You keep the locksets you have and change only the cylinders, so a multi-tenant building with a key control problem gets fixed door by door instead of through a full hardware replacement.
6) Will the Medeco 20200F1 work in a Schlage or Best lockset?
No. The 20200F1 is cut for Falcon B, LY, X, S and T series cylindrical hardware, and key-in-knob cylinders are brand-specific in their tailpiece and cam arrangement. For other manufacturers' locksets you need the Medeco key-in-knob cylinder built for that brand; Medeco publishes over 100 cylinder and tailpiece configurations across the line, so the equivalent almost certainly exists, but it is a different part number from this one.
7) What finishes does the Medeco 20200F1 key-in-knob cylinder come in to match existing door hardware?
Thirteen finishes are orderable: 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 building already standardized on 626 satin chrome knobs and levers (the common commercial spec), order 626 and the cylinder face disappears into the existing trim.
8) Can I key Medeco 20200F1 cylinders alike across a building, or into a master key system?
Yes, within one platform. The 20200F1 is a 6-pin cylinder available on Biaxial or M3, and cylinders on the same platform and keyway can be keyed alike or built into a master system. Six pins gives the chamber depth a multi-level master system needs. Cylinders ordered on different platforms will not share a key, so standardize the whole facility on one before you start keying.
9) Is the Medeco 20200F1 rated for commercial traffic or is it a residential cylinder?
Commercial. The 20200F1 is classified as commercial hardware and meets ANSI A156.5 Grade 1, the heavy-use grade, with brass machined internals. It is specified into office buildings, schools, healthcare, government and municipal facilities, retail, warehouses and multi-tenant residential. For a high-cycle opening like a main entry or a mechanical room, Grade 1 is the level a facility spec normally calls for.
10) Do I need to buy anything else to install a Medeco 20200F1 in a Falcon knob lock?
For a straight cylinder swap on Falcon B, LY, X, S or T series hardware, the cylinder replaces what is already in the knob or lever and the rest of the lockset stays. What you do need to settle on the order is the keyway platform (Biaxial or M3), the finish to match the trim, and whether you want it Pinned to a key code or Sub-Assembled for your own shop to pin. Those three choices define the part; get one wrong and the cylinder will not work in your key system even though it fits the lock.
11) Can the Medeco 20200F1 be used in a padlock or an auxiliary deadlock, not just a door knob?
Yes. Beyond knob and lever cylindrical locksets, the 20200F1 retrofits padlocks and bored-type auxiliary deadlatches and deadlocks. That lets a facility run one key platform across entry doors, gate and equipment padlocks, and secondary deadlocks instead of carrying separate key systems for each.
