Medeco 12028006-19-G3 – Frequently Asked Questions

1) Do my existing Medeco keys work with this replacement plug, or do I need new keys?
The plug is cut for the Medeco G3 keyway with a 6-pin Biaxial configuration. Keys operate it only if they are G3 keyway blanks. If your building runs a different Medeco keyway, the existing keys will not enter this plug and you would need the plug in your keyway instead. G3 is a restricted keyway, so duplication is controlled.
2) Is this a complete cylinder or just the plug?
Just the plug, the rotating core that the key enters. The shell, pins, springs and cam are not part of it. A locksmith rebuilding or rekeying a Maxum deadbolt orders it as a service part; it is not a standalone lock.
3) Can a Corbin Russwin cylinder plug be used to replace the plug in a Medeco Maxum deadbolt?
No. The Medeco 12028006-19-G3 is a Biaxial 6-pin plug cut for the Medeco G3 keyway and built as a direct-fit replacement for the Maxum Deadbolt line, excluding Captive configurations. The Corbin Russwin 121K11-D2 and 121K11-L4 are 1000 Series mortise cylinder plugs, and the 253K66 is a 3000 rim cylinder plug - each is keyed and dimensioned for its own Corbin Russwin housing, not for a Medeco Maxum deadbolt shell.
4) What does Medeco Biaxial mean for a facility running a master key system?
Biaxial pins have to be lifted to the right height and rotated to the right angle before the plug turns. That second axis multiplies the usable combinations, which is what lets a 6-pin Biaxial cylinder carry a large master key system without duplicate bittings, and it is what gives the cylinder its pick and bump resistance. Replacing a worn plug with the same Biaxial G3 plug keeps that system intact.
5) Does the plug come pinned and keyed, or do I have to pin it myself?
Plan on pinning it. The part is supplied as a 6-pin Biaxial G3 plug for a locksmith to key into your existing system, which is the point of buying the plug rather than a whole cylinder. Medeco Biaxial pins are angled, so keying requires the Medeco tooling and the correct pin set.
6) What is the difference between a cylinder plug and a cylinder plug retainer?
They are different parts of the same assembly. The Medeco 12028006-19-G3 is the plug itself - the rotating Biaxial 6-pin core in the G3 keyway that the key enters. The Corbin Russwin 219F88-8 is a cylinder plug retainer, the piece that holds a plug in its shell. If the key turns but the cylinder is loose or the plug backs out, a retainer is the part in question, not a replacement plug.
7) Our facility standardizes on Grade 1 hardware - how does the Medeco Maxum plug compare to the Corbin Russwin cylinder plugs?
The Corbin Russwin 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs and the 219F88-8 is a Grade 1 cylinder plug retainer. The Medeco 12028006-19-G3 is a commercial-grade replacement plug built on Medeco's Biaxial pin technology with a restricted G3 keyway, which adds key control against unauthorized duplication on top of the pick resistance of the angular pin cuts. The choice generally follows which lock platform the facility already runs.
8) Will satin nickel match the other Medeco hardware on my doors?
The finish is 619 satin nickel, the standard BHMA code for satin nickel plated finishes, so it lines up with other hardware specified 619. Note that on a deadbolt only the plug face shows at the keyway, so a slight difference against an older, weathered rose is normal.
9) Is this plug meant for commercial buildings or residential doors?
It is classified commercial, and it is aimed at places running restricted key control: office buildings, schools, hospitals, government facilities and multi tenant residential on Maxum deadbolts. It works fine on a residential door that already has a Maxum, but the reason to buy it is key control rather than a basic lock swap.
10) Is the Corbin Russwin 121K11-L4 a substitute for the 121K11-D2?
Both are Corbin Russwin Grade 1 1000 Series mortise cylinder plugs; the D2 and L4 suffixes identify different variants within that series. Neither one substitutes for the Medeco 12028006-19-G3, which is a Biaxial G3 plug for the Maxum Deadbolt.
