Why Medeco Maxum?

Medeco is recognized in the commercial security industry for its Biaxial cylinder technology, which provides resistance to picking and unauthorized key duplication through its two-axis pin rotation design. The 12029006-20-G3 cylinder plug delivers the same high-security performance as the original factory component, making it the correct choice for service, replacement, or rekeying of Medeco Maxum Deadbolt installations where the G3 restricted keyway program is in use.

Medeco 12029006-20-G3 – Frequently Asked Questions

1) What exactly is the Medeco 12029006 part, and what lock does it go in?
It's the cylinder plug, the rotating core that the key enters, for a Medeco Maxum Deadbolt. It is not a complete cylinder and not a complete deadbolt. Model designation is 12029006-20-G3, supplied for service, replacement, or rekeying of existing Maxum deadbolt installations.
2) Will a Medeco 12029006 plug work with my existing Medeco keys?
Only if your system runs the G3 keyway. This plug is cut for the restricted G3 keyway program with Biaxial 6-pin, captive design. Keys from a different Medeco keyway will not enter it. If your building is keyed to another Medeco restricted keyway, order the plug for that keyway instead.
3) Can I use a Corbin Russwin cylinder plug instead of the Medeco Maxum plug?
No. Corbin Russwin plugs such as the 121K11-D2 and 121K11-L4 are 1000 Series mortise cylinder plugs, and the 253K66 is a 3000 Series rim cylinder plug. Different manufacturer, different cylinder platform, different keyway. None of them drop into a Medeco Maxum deadbolt cylinder. If you are working on Corbin Russwin hardware, those are the parts to look at; for Maxum, the plug must be the Medeco one.
4) Why is Medeco Biaxial different from a standard pin tumbler plug?
Biaxial pins rotate on two axes rather than simply elevating, which is what gives the cylinder its pick resistance and its resistance to unauthorized key duplication. That two-axis geometry is also why the plug has to come from Medeco and cannot be substituted with a generic pin tumbler plug.
5) I need to rekey a building full of Medeco Maxum deadbolts. Is swapping plugs the right approach?
It is one route. Replacing the plug gives you a fresh core in the existing cylinder housing, which keeps the deadbolt body and trim in place and only changes what the key turns. Because the G3 keyway is a restricted program, the replacement plugs and the keys stay under your key control, so the whole set of openings can be brought back onto one master system without pulling deadbolts off doors.
6) Does the Medeco 12029006 include the deadbolt or the full cylinder housing?
No. What you get is the plug alone, catalogued as a replacement part. The deadbolt body, cylinder shell, cam, tailpiece, and keys are separate. Plan on a locksmith pinning and assembling it into the existing Maxum cylinder.
7) My cylinder plug keeps backing out - is the Corbin Russwin 219F88-8 the part I need, or the Medeco 12029006?
Those solve different problems. The Corbin Russwin 219F88-8 is a Grade 1 cylinder plug retainer, the piece that holds a plug in its cylinder. The Medeco 12029006 is the plug itself, a captive Biaxial 6-pin G3 keyway plug for the Maxum Deadbolt. If the plug is intact and only the retention has failed on Corbin Russwin hardware, the retainer is the part; if the Medeco plug itself needs replacement or rekeying, order the 12029006.
8) For standardizing a facility on one keyway program, how does the Medeco 12029006 differ from the Corbin Russwin 121K11 plugs?
The Medeco 12029006 plug is part of the Medeco restricted G3 keyway program and uses Biaxial two-axis pin rotation for resistance to picking and unauthorized key duplication, which is what ties it to a controlled key system. The Corbin Russwin 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs supplied by keyway designation, so a facility standardizing on Corbin Russwin mortise cylinders would specify one of those keyways instead. The two programs are separate and keys are not shared between them.
9) Is this a residential or commercial-grade part?
Commercial. Medeco lists the Maxum deadbolt plug for commercial use, and the typical applications are office buildings, schools, hospitals, government buildings, financial institutions, multi-tenant properties, and industrial facilities running key control programs.
10) What finish does the Medeco Maxum deadbolt plug come in?
Antique Nickel, finish code 620. That's the only finish offered on this plug, so if the rest of your deadbolt trim is a different finish the face of the plug will not match.
