Medeco 2051027T-06-DLT – Frequently Asked Questions

1) What do I have to specify when ordering a Medeco 2051027 retrofit deadbolt cylinder?
Three things. First the keyway and technology, either Biaxial or M3. Second the pinning state: Pinned, Sub-Assembled, or Sub-Assembled No Slider, which lets a locksmith pin it into an existing system rather than take it factory keyed. Third the finish, from 13 options including 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.
2) Can my locksmith key the Medeco 2051027 into our existing master key system?
Yes, if you order it in one of the unpinned states. Besides factory Pinned, the 2051027 comes Sub-Assembled and Sub-Assembled No Slider so a locksmith can pin it to an existing Medeco system in the shop. Choose the keyway to match your system: Biaxial or M3. The key control is patent protected, so blanks and duplication stay restricted to your authorized channel.
3) Does the Medeco 2051027 deadbolt cylinder meet Grade 1 and UL437 for a government or healthcare facility?
The 2051027 is certified to ANSI A156.30 Level A for patent-protected key control and physical strength, and ANSI A156.5 Grade 1 for heavy-use commercial applications. Medeco M4 Key-in-Knob/Lever cylinders are UL437 listed for drill and pick resistance. That combination is what spec writers ask for on restricted-key openings in government, healthcare and education buildings. The part is classed as commercial, not residential.
4) Can I use the Medeco 2051027 in a rim exit device or a mortise lock?
No. The 2051027 is a Key-in-Knob/Lever style retrofit cylinder made specifically for Corbin Russwin DL2100/DL3100 and Yale 3300/3500/3600 deadbolts. For a rim exit device you want a rim cylinder such as the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal cam, or the Corbin Russwin 3070 6-pin rim housing with a 1-7/8 inch tailpiece. For a mortise lock, a mortise cylinder like the Corbin Russwin 1000 Series 1-1/2 inch with an A02 straight cam is the right family.
5) Our building is on a BEST interchangeable core system. Is the Medeco 2051027 a substitute?
No. The 2051027 is a fixed 6-pin retrofit cylinder, not an interchangeable core, so it will not drop into an IC housing or share your control key. If you are staying on interchangeable core, look at BEST cores such as the 1C Series standard 5-pin core, the 1CB Peaks 150 Series core, or the 1CDF drill-resistant patented 7-pin core. Mixing the 2051027 into an IC building means those deadbolt openings sit on a separate Medeco key.
6) What is a lower-cost alternative to the Medeco 2051027 for replacing a deadbolt cylinder?
The Kaba Ilco 1549 Series is a key-in-deadbolt replacement cylinder and is a standard-keyway option when patent-protected key control is not required. The Medeco 2051027 is a 6-pin retrofit cylinder certified to ANSI A156.30 Level A and ANSI A156.5 Grade 1 with UL437 listing on M4, and its keys are restricted against unauthorized duplication; the Ilco 1549 is an open-keyway deadbolt cylinder. Choose the 2051027 when the goal is key control on Corbin Russwin DL2100/DL3100 or Yale 3300/3500/3600 deadbolts, and the 1549 when you only need a working cylinder.
7) I need a high-security cylinder for a Sargent knob or lever instead of a Corbin Russwin deadbolt - is the Medeco 2051027 the right part?
No. The Medeco 2051027 is built to replace cylinders in Corbin Russwin DL2100 and DL3100 deadbolts and Yale 3300, 3500 and 3600 Series deadbolt locks. For Sargent knob and lever hardware, the Kaba Ilco 1579 Series knob and lever cylinder is the one built for Sargent. Medeco offers over 100 cylinder designs and tailpiece configurations, so a different Medeco retrofit part number would cover Sargent - the 2051027 is not it.
8) What should I use for an aluminum storefront deadlock instead of the Medeco 2051027?
For Adams Rite narrow stile hardware, the 4036 mortise cylinder is a five-pin Grade 1 cylinder for doors 1/2 inch minimum thickness, and the 4025 is a five-pin cylinder pull with through-screws for the MS1847 deadlock. The Medeco 2051027 is dimensioned for Corbin Russwin DL2100/DL3100 and Yale 3300/3500/3600 Series deadbolts and will not serve a narrow stile storefront stile.
9) Will a Medeco 2051027 match the brass and bronze hardware already on my doors?
There are 13 finishes to choose from, so a property manager standardizing a building can usually match what is already hanging: 605 Bright Brass, 606 Satin Brass, 609 Antique Brass, 611 Bright Bronze, 612 Satin Bronze, 613 Dark Bronze Oil-Rubbed, 624 Dark Bronze, 618 Bright Nickel, 619 Satin Nickel, 20 Antique Nickel, 622 Flat Black, 625 Bright Chrome and 626 Satin Chrome. The cylinders themselves are machined brass.
10) What is a cheaper alternative to a Medeco retrofit deadbolt cylinder if I do not need restricted keys?
If key control is not the driver, a standard replacement deadbolt cylinder will do the mechanical job. Kaba Ilco offers the 1549 Series key-in-deadbolt cylinder and the 1539 Series key-in-knob/lever universal cylinder, both catalogued for deadbolt function. What you give up is the piece the 2051027 exists for: ANSI A156.30 Level A patent-protected key control and UL437 drill and pick resistance on the M4.
11) Is Biaxial or M3 the right keyway choice for a Medeco 2051027?
Match whatever your existing Medeco system runs on. The 2051027 is offered in both Biaxial and M3. If you are starting a new restricted system rather than extending one, note that the published ANSI A156.30 Level A and A156.5 Grade 1 certifications cover M4 and M3, and UL437 drill and pick resistance is cited for M4.
12) Can I use a Corbin Russwin 1000 mortise cylinder in place of the Medeco 2051027?
No - they are different cylinder formats. The Corbin Russwin 1000 Series is a 1-1/2 inch mortise cylinder with an A02 straight cam, which threads into a mortise lock body. The Medeco 2051027 is a key-in-knob/lever style retrofit cylinder for Corbin Russwin DL2100/DL3100 and Yale 3300/3500/3600 Series deadbolts. If your opening uses a mortise lock case, the 1000 Series applies; if it is one of those deadbolts, use the 2051027.
13) We want one keying system across a whole building - how does the Medeco 2051027 compare to a small-format interchangeable core setup?
The Medeco 2051027 is a fixed retrofit cylinder that is rekeyed by pinning, ordered as Pinned, Sub-Assembled, or Sub-Assembled No Slider, in Biaxial or M3 keyway technology. An interchangeable core program such as the BEST 1C Series 5-pin core or the drill-resistant 1CDF 7-pin patented core lets staff swap cores by hand with a control key instead of disassembling hardware. Both approaches standardize a facility; the Medeco route keeps the existing Corbin Russwin and Yale deadbolt bodies in place, while the BEST route requires core-accepting housings.
14) Is the Detex MC65 an equivalent to the Medeco 2051027?
They are not interchangeable. The Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, which is an open keyway used in mortise-threaded housings. The Medeco 2051027 is a 6-pin retrofit cylinder for Corbin Russwin DL2100/DL3100 and Yale 3300/3500/3600 deadbolts, offered in Biaxial or M3 keyway technology with restricted key duplication.
15) Is there a non-keyed option if I just need to fill the cylinder hole?
For a non-functioning fill, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is a dummy unit rather than a working lock. The Medeco 2051027 is a keyed 6-pin retrofit cylinder that operates Corbin Russwin DL2100/DL3100 and Yale 3300/3500/3600 Series deadbolts, so order it only where the door is actually locked and keyed.
