Medeco 11-0A21-19 – Frequently Asked Questions

1) Will the Medeco 11-0A21-19 thumbturn work with a standard Medeco cylinder, or only M3?
The 11-0A21-19 thumbturn is built for the Medeco M3 Captive Blade cylinder system specifically. If the cylinder in the door is not an M3 Captive Blade, this is the wrong turn piece. Confirm the cylinder platform before ordering, because the turn mates to the M3 captive blade tailpiece arrangement rather than a generic cam.
2) Is this Medeco thumbturn a full lock or just the turn piece?
Just the turn piece. The 11-0A21-19 is a replacement component, not a complete deadbolt or cylinder assembly. You are buying the inside thumbturn that drives an existing M3 Captive Blade cylinder, so the cylinder, housing and bolt all stay in the door.
3) One of our Medeco M3 thumbturns broke. Do we have to replace the whole lock?
No. The 11-0A21-19 is sold as a service part so an M3 Captive Blade assembly can be repaired in place. Swap the turn, leave the cylinder and keying alone, and the opening stays on the existing key system. That matters on a high-security suite, where replacing the cylinder would mean re-keying.
4) Can I use a residential-style Medeco thumbturn in a commercial building?
Yes. Residential style here describes the shape of the turn, a traditional, clean profile, not the grade of use. Medeco classes the 11-0A21-19 as commercial, and it is used for service work on M3 openings in offices, healthcare, schools, government buildings, hotels and multi-tenant residential managed on commercial hardware.
5) Does a Medeco thumbturn like the 11-0A21-19 need to be keyed or handed?
It is a turn piece, not a keyed component, so there is no keyway or key bitting involved. What you do have to get right is the cylinder platform: it must be M3 Captive Blade. Order by the model number 11-0A21-19 and the 619 satin nickel finish.
6) What finish does the Medeco 11-0A21-19 thumbturn come in?
One finish only: 619 Satin Nickel, applied at the factory. If you are matching other turns or roses on the same suite of doors, 619 is the BHMA designation for satin nickel, so it will key visually to other 619 trim in the building.
