Medeco 2020049T-26-DLT – Frequently Asked Questions

1) Will the Medeco 2020049 cylinder fit a Schlage D Series lever lock?
Yes. The 2020049 is a key-in-knob/lever retrofit cylinder built to drop into Schlage A, AL and D Series cylindrical hardware, along with Arrow QL and MLX Series levers, the SL00 knob lock and LX01 lever lock, Dorma CL700 Series, Cal-Royal, and Falcon B Series. It swaps the cylinder only, so the lockset, chassis and door prep stay as they are.
2) Can I upgrade my building's existing knob and lever locks to Medeco keys without replacing the locksets?
That is exactly what the 2020049 does. It replaces the cylinder inside knob-type and lever-type cylindrical locksets, padlocks, and bored auxiliary deadlatches and deadlocks from the major hardware brands, so a facility can move to Medeco patented key control door by door without buying new locksets. Medeco publishes over 100 cylinder designs and tailpiece configurations to cover the range of host hardware.
3) What is the difference between the Biaxial and M3 versions of the Medeco 2020049 cylinder?
Biaxial and M3 are two different Medeco keyway technologies, and the 2020049 is sold in both. The choice is not about the door, it is about the key system you already run: order the technology that matches your existing Medeco master key system so the new cylinder keys into it. If you are starting a new system, pick one technology and stay on it across the facility.
4) Should I order the Medeco 2020049 pinned or sub-assembled?
Pinned means the cylinder arrives keyed and ready to install. Sub-assembled ships without final pinning so a locksmith with Medeco factory authorization can key it to an existing system on the bench. There is also a Sub-Assembled, No Slider option for shops that pin and set the slider themselves. If you do not do your own Medeco keying, order pinned.
5) Is the Medeco 2020049 cylinder drill and pick resistant?
UL 437 listed for drill and pick resistance, with utility patent pending key control. 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 commercial openings. The body is machined brass.
6) Is a 6-pin cylinder needed, or will 5-pin work for a commercial master key system?
The 2020049 is a 6-pin cylinder. The sixth pin chamber gives more usable key changes and more room to build a master key system without collisions, which is why it is the configuration specified for commercial buildings running multiple levels of keying. For a single standalone opening the extra chamber matters less, but on a facility-wide system it is what keeps the master keying expandable.
7) Can I get Medeco retrofit cylinders in oil rubbed bronze to match existing lever trim?
Thirteen finishes are offered on the 2020049: 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. Match the cylinder face to the BHMA number already on your lever trim and the swap will not read as a repair.
8) Is the Medeco 2020049 rated for a high traffic commercial door or is it a residential cylinder?
Commercial. The 2020049 carries ANSI A156.5 Grade 1, the heavy use commercial grade, and is built from machined brass. It is the cylinder specified for office buildings, schools, healthcare, retail, government facilities, warehouses and multi-tenant residential, not for light duty residential hardware.
9) Does replacing a lockset cylinder with the Medeco 2020049 affect the lock's function or handing?
No. The 2020049 changes the keying and key control only. The lockset's function, handing, backset and door prep are set by the chassis you are keeping, so a storeroom lock stays a storeroom lock after the swap. What you do need to confirm is the tailpiece: Medeco builds different tailpiece configurations for different host locksets, and the 2020049 covers the Arrow QL/MLX, Schlage A/AL/D, Falcon B, Dorma CL700 and Cal-Royal families.
