Medeco 2020070T-26-DLT – Frequently Asked Questions

1) Will a Medeco 2020070 cylinder fit my Arrow MK Series knob locks?
Yes. The Medeco 2020070 is a 6-pin key-in-knob/lever retrofit cylinder built specifically for Arrow MK Series and LSDA 100 Series knob locks. You keep the existing lockset in the door and swap only the cylinder, so a security upgrade doesn't mean re-prepping doors or buying new hardware.
2) Can I put a Medeco key-in-knob cylinder in a lever lock or a padlock, not just a knob?
The 2020070 retrofits knob-type cylindrical locksets, lever-type cylindrical locksets, padlocks, and bored-type auxiliary deadlatches and deadlocks. The named hardware fits are Arrow MK Series and LSDA 100 Series knob locks, so for anything outside those, match the tailpiece configuration to the lock you're converting.
3) What's the difference between the Biaxial and M3 versions of the Medeco 2020070?
Those are the two key systems offered on the 2020070. Biaxial and M3 are separate Medeco keyways and are not interchangeable, so order the one that matches the keys and key system already in your building. If you're starting a new system on a facility, pick one and standardize, because mixing them means two sets of keys on the same site.
4) Is the Medeco 2020070 cylinder rated for high-traffic commercial doors?
It's a commercial cylinder, certified to ANSI A156.30 Level A for key control and physical strength and ANSI A156.5 Grade 1 for heavy-use applications. Body and components are machined brass. Grade 1 is the highest of the three ANSI grades, which is what a spec on an office, school, or healthcare opening will normally call for.
5) Is this Medeco knob cylinder drill and pick resistant?
Medeco M4 key-in-knob cylinders are UL437 listed for drill and pick resistance. The 2020070 also carries utility patent-pending key control, which restricts unauthorized key duplication, so keys can't be cut at a hardware counter. That combination is the reason most buyers move from a stock Arrow or LSDA cylinder to this one.
6) Do I have to replace the whole knob lock to upgrade security on my Arrow MK locks?
No. The 2020070 is a drop-in cylinder change, which is the whole point of Medeco's retrofit line, over 100 cylinder designs and tailpiece configurations covering the popular security hardware. On a building with dozens of Arrow MK or LSDA 100 knobs, you upgrade key control across the site without touching the doors, the prep, or the latches.
7) What does "Sub-Assembled" mean when ordering a Medeco cylinder, versus pinned?
Three build states are offered: Pinned, Sub-Assembled, and Sub-Assembled No Slider. Pinned comes keyed and ready to install. Sub-Assembled ships for a locksmith or a facility with its own key system to pin to their bitting. Sub-Assembled No Slider omits the slider component for shops keying Biaxial work themselves. If you don't run a key machine, order Pinned.
8) Can I get Medeco cylinders to match the knob finishes already on my doors?
Thirteen finishes are offered: Antique Nickel (20), Bright Brass (605), Satin Brass (606), Antique Brass (609), Bright Bronze (611), Satin Bronze (612), Dark Bronze Oil-Rubbed (613), Bright Nickel (618), Satin Nickel (619), Flat Black (622), Dark Bronze (624), Bright Chrome (625), and Satin Chrome (626). For a building already on satin chrome knobs, 626 is the usual match; 626 and 630 are the most common commercial finishes in the field.
9) Can I key Medeco 2020070 cylinders into a master key system across a facility?
Yes. It's a 6-pin cylinder, and 6 pins is what gives you the chamber depth for multi-level masterkeying across a site. Order Pinned if you want them keyed to your system by the supplier, or Sub-Assembled if your own locksmith pins them into an existing Medeco Biaxial or M3 system.
