Medeco 20200L1T-26-DLT – Frequently Asked Questions

1) Will the Medeco 20200L1 cylinder fit an LSDA LH1000 lever lockset?
Yes. The 20200L1 is a 6-pin key-in-lever retrofit cylinder built specifically for LSDA 100, L100, LH1000 and LX1000 Series lever-type cylindrical locksets. It drops into the existing lever, so you upgrade key control without pulling and replacing the whole lockset.
2) Can I upgrade LSDA lever locks to high security without replacing the locksets?
That is exactly what this cylinder is for. Swapping the 20200L1 into an existing LSDA 100, L100, LH1000 or LX1000 lever gets you UL437 drill and pick resistance and patent-pending key control while the lockset, prep and door stay untouched. Medeco publishes over 100 cylinder and tailpiece configurations, so other lever and knob families in the same building can usually be brought onto the same key system the same way.
3) What is the difference between the Biaxial and M3 versions of the Medeco 20200L1?
Those are the two keyway and technology platforms this cylinder is built on, and they are not interchangeable keys. Pick the one that matches the Medeco system already running in the building: order M3 if your existing keys are M3, Biaxial if the site is on Biaxial. Mixing platforms means a second set of keys and a second master key system.
4) Does the Medeco 20200L1 meet Grade 1 commercial requirements?
It carries ANSI/BHMA A156.5 Grade 1 for heavy-use commercial duty and ANSI A156.30 Level A for patent-protected key control and physical strength, plus a UL 437 listing for drill and pick resistance. That combination is what most institutional and government specs call for on a high-security cylinder.
5) Should I order the Medeco cylinder pinned or sub-assembled?
Three build states are offered: Pinned, Sub-Assembled, and Sub-Assembled No Slider. Pinned ships ready to install on a keying order. Sub-assembled is for locksmiths who pin and key the cylinder themselves on their own system. The no-slider version leaves the slider out for shops doing their own Biaxial slider work.
6) Is the Medeco 20200L1 a mortise or rim cylinder?
Neither. It is a key-in-knob/lever style cylinder, the kind that seats inside the lever or knob of a cylindrical lockset rather than threading into a mortise case or mounting behind a rim device. If your opening uses a mortise lock body or a rim exit device, you need a different Medeco cylinder from that family.
7) What finishes can I get the Medeco key-in-lever cylinder in to match existing hardware?
Thirteen finish choices: 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 lever openings 626 Satin Chrome or 613 oil-rubbed bronze will match what is already on the door.
8) Is this Medeco cylinder rated for commercial traffic or is it residential grade?
Commercial. Machined brass construction, 6-pin, and Grade 1 certified for heavy-use commercial openings, which is why it shows up in schools, healthcare, government buildings and multi-tenant properties where key control is the driver.
