Medeco 12028006-12-G3 Cylinder Plug for Maxum Deadbolt, Biaxial 6-Pin G3 Keyway, Satin Bronze Clear Coated

The Medeco 12028006-12-G3 is a precision-engineered replacement cylinder plug designed exclusively for the Maxum Deadbolt (except Captive models), featuring Medeco's renowned Biaxial pin tumbler technology with a 6-pin configuration and G3 keyway. Finished in Satin Bronze Clear Coated, this plug is engineered for commercial-grade applications where high-security key control and reliable lock performance are essential. Medeco's Biaxial technology elevates security beyond conventional cylinders by requiring keys to align pins both vertically and rotationally, making unauthorized duplication and picking significantly more difficult.

  • 6-Pin Configuration: Six-pin cylinder plug delivers enhanced pick resistance and key combination depth compared to standard 5-pin designs, ideal for high-security lock installations.
  • G3 Keyway: Features the proprietary Medeco G3 keyway for controlled key duplication and restricted access key systems, supporting key control programs.
  • Maxum Deadbolt Compatibility: Engineered specifically as a replacement plug for Medeco Maxum Deadbolt cylinders (except Captive variants), ensuring precise fit and proper function.
  • Satin Bronze Clear Coated Finish: Factory-applied Satin Bronze Clear Coated finish coordinates with complementary door hardware finishes and resists everyday wear.
  • Commercial-Grade Replacement Part: Classified as a commercial replacement part and accessory, suitable for professional locksmith installation and high-demand commercial environments.

Medeco 12028006-12-G3 – Frequently Asked Questions

1) Will the Medeco 12028006-12-G3 plug fit any Maxum deadbolt?
It fits Medeco Maxum Deadbolt cylinders with one exception: Captive models are excluded. If the deadbolt you are servicing is a Captive Maxum, this plug is not the right part. For all other Maxum deadbolts it is the factory replacement plug.
2) Can I rekey my existing Medeco keys to this plug, or does it have to be G3?
The plug is cut for the Medeco Biaxial G3 keyway with six pin chambers, so it only accepts G3 Biaxial keys. If your building's key system runs a different Medeco keyway, or a 5-pin cylinder, keys from that system will not enter or turn this plug. Match the keyway and the pin count to the existing system before you order.
3) I just need the plug, not a whole new cylinder. Is that what this is?
Correct. The 12028006-12-G3 is the plug alone, the rotating core that carries the pins and the keyway. It is a replacement part, so the deadbolt cylinder housing, cam, tailpiece, springs and top pins stay in the lock. Order it when the plug is worn, drilled, or the site is being moved to a different key system.
4) Can a Corbin Russwin 253K66 rim cylinder plug be used in place of the Medeco 12028006-12-G3?
No. The Medeco 12028006-12-G3 is a replacement cylinder plug built for the Medeco Maxum Deadbolt (except Captive models) with Biaxial 6-pin construction and the G3 keyway. The Corbin Russwin 253K66 is a 3000 rim cylinder plug, so it belongs to a rim cylinder housing rather than a Maxum deadbolt cylinder, and it does not carry the Medeco Biaxial pinning or G3 keyway that a Medeco key system requires. If the opening is keyed into a Medeco G3 system, the plug has to stay Medeco.
5) What is the mortise equivalent if the opening uses a mortise cylinder instead of a Maxum deadbolt?
The Medeco 12028006-12-G3 plug fits Maxum Deadbolt cylinders only. For a mortise cylinder body, Corbin Russwin offers plug-only parts in the 1000 Series, such as the 121K11-D2 and the 121K11-L4, which are Grade 1 mortise cylinder plugs supplied without the cylinder shell. The two differ by keyway designation, D2 and L4, so the one you order has to match the existing Corbin Russwin key system.
6) Why does the Medeco Biaxial plug need special pinning compared to a standard pin tumbler cylinder?
Biaxial pins have to be rotated as well as elevated, so the key cuts are angled front-to-back in addition to being cut to depth. That means a Biaxial 6-pin plug like the 12028006-12-G3 has to be pinned and keys cut on Medeco equipment by an authorized dealer, not on a standard duplicator. That dual-axis requirement is also what makes the keys hard to copy and the cylinder harder to pick.
7) What finish is the Medeco 12028006-12-G3 cylinder plug, and will it show on the outside of the door?
It is finished 612 Satin Bronze with a clear coat applied at the factory. The plug face is the visible part of the cylinder at the keyway, so the finish matters if the rest of the deadbolt trim is a different bronze or brass tone.
8) I have a mortise or rim cylinder, not a Maxum deadbolt. What plug should I be looking at?
This Medeco plug is cut for the Maxum deadbolt and will not serve a mortise or rim cylinder. For a mortise cylinder plug, ZenSupply carries the Corbin Russwin 1000 Series plugs, 121K11-D2 and 121K11-L4, in their respective keyways. For a rim cylinder, the Corbin Russwin 253K66 is the 3000 Series rim cylinder plug. Those are Corbin Russwin keyways, so they suit a building already keyed to that system rather than a Medeco one.
9) Does a cylinder plug come with the retainer or clip that holds it in?
No. The 12028006-12-G3 is the plug on its own. Retainers are separate items, and they are keyway-family specific, for example the Corbin Russwin 219F88-8 cylinder plug retainer serves Corbin Russwin cylinders, not a Medeco Maxum. For the Maxum, reuse the existing retaining hardware from the cylinder you are servicing or source the Medeco part for it.
10) Can I standardize several doors on the Medeco G3 6-pin plug and master key them together?
Yes, that is the usual reason to buy it. Because G3 is a proprietary restricted keyway, plugs ordered in the same keyway can be pinned into one master key system with controlled duplication, which is why it turns up in schools, hospitals and multi-tenant offices. The six chambers give more available combinations than a 5-pin cylinder, which matters when a master system has to carry a lot of change keys.
11) Is the Corbin Russwin 219F88-8 the same kind of part as the Medeco 12028006-12-G3?
No. The 12028006-12-G3 is the plug itself, the rotating core that carries the pins and accepts the Biaxial G3 key in a Maxum Deadbolt cylinder. The Corbin Russwin 219F88-8 is a Grade 1 cylinder plug retainer, the small component that holds a plug in its housing. A retainer will not replace a worn or rekeyed plug, and the two are ordered for different repairs.
12) What is the difference between the Corbin Russwin 121K11-D2 and 121K11-L4 when I am sourcing a plug-only part?
Both are Grade 1 1000 Series mortise cylinder plugs supplied as plug only, and both carry the cylinder function. The suffix is the keyway: D2 on one and L4 on the other. Pick the suffix that matches the keyway already in the building, since a plug in the wrong keyway will not accept the existing keys. That is the same logic behind the Medeco 12028006-12-G3, where the G3 designation ties the plug to a specific Medeco keyway.
13) Is this a commercial part or is it meant for houses?
Medeco lists the 12028006-12-G3 as a commercial item, and it is a genuine part from Medeco's tools, parts and accessories program. It is the sort of plug used where a facility runs restricted key control, offices, schools, healthcare, government buildings, and multi-tenant property.
