Medeco 12029006-24-G3 – Frequently Asked Questions

1) Will the Medeco 12029006-24-G3 plug fit any Medeco deadbolt, or only the Maxum?
It is built for the Medeco Maxum Deadbolt platform specifically. The 12029006-24-G3 is a direct replacement plug for Maxum deadbolt housings, so it drops into a compatible Maxum body and functions as original. If the deadbolt on your door is a different Medeco line or another brand entirely, this is the wrong plug.
2) Can I use my existing Medeco keys with this replacement plug?
Only if your keys are cut for the Medeco Biaxial G3 keyway and your system is 6-pin. This plug is a captive Biaxial 6-pin unit on the G3 keyway. Keys from a different Medeco keyway will not enter it, and a 5-pin bitting will not key it correctly. A locksmith will normally rekey the plug to your existing G3 system so it runs on the same keys as the rest of the building.
3) Can a Corbin Russwin 253K66 rim cylinder plug be used in place of a Medeco 12029006-24-G3?
No. The Medeco 12029006-24-G3 is a captive Biaxial 6-pin plug with the G3 keyway made as a direct replacement for the Medeco Maxum Deadbolt housing, so it only drops into that platform. The Corbin Russwin 253K66 is a 3000 rim cylinder plug, built for a Corbin Russwin rim cylinder and its own keyway family. They are not interchangeable parts, and swapping one in would also break a Medeco restricted key system, since the G3 keyway is what controls key duplication.
4) What is the equivalent to the Medeco 12029006-24-G3 if the opening uses a mortise cylinder instead of a deadbolt?
The 12029006-24-G3 plug is engineered for the Medeco Maxum Deadbolt platform, so it will not serve a mortise cylinder. For a mortise application on a Grade 1 opening, the Corbin Russwin 121K11-D2 and 121K11-L4 are 1000 Series mortise cylinder plugs, supplied plug-only and differing from each other by keyway designation (D2 versus L4). Choose the one matching the keyway already in your Corbin Russwin system; they do not carry Medeco Biaxial keying.
5) What does Medeco's Biaxial design actually do that a standard pin tumbler plug does not?
Biaxial cylinders use keys cut at two different angles, so each pin has to be both elevated and rotated correctly before the plug turns. That second axis is what raises pick and manipulation resistance over a conventional pin tumbler plug, and it is also why blanks and cuts have to come from a Medeco-authorized source.
6) Why would I buy a cylinder plug instead of a whole new deadbolt cylinder?
Replacing just the plug lets you keep the existing Maxum deadbolt body and trim on the door and change only the keyed core. That is the usual move when a tenant turns over, a key is lost, or you are folding one opening into a new key control program. It is classified as a commercial replacement part and assumes professional installation, since the captive design keeps the plug retained in the lock body and it will not come out without the right tools.
7) Is this Medeco plug suitable for a restricted key control program across a campus or facility?
That is what the G3 keyway is for. G3 is a restricted Medeco keyway, so duplication is controlled and keys are not cut at a hardware counter. Facilities running controlled key access, schools, healthcare, and government buildings among them, use it to keep an audit path on who holds keys. It is specified as a commercial part, not a residential one.
8) I need a plug for a Corbin Russwin mortise cylinder, not a Medeco. What should I be looking at?
The Medeco Maxum plug will not fit Corbin Russwin hardware. For a Corbin Russwin 1000 Series mortise cylinder, the plug-only part is the 121K11, available in the D2 and L4 keyways. For a 3000 Series rim cylinder, the plug is the 253K66. If the issue is the retaining piece rather than the plug itself, the Corbin Russwin 219F88-8 is the cylinder plug retainer.
9) My Medeco plug spins but will not stay seated - do I need a new 12029006-24-G3?
Not necessarily. A plug that turns but does not retain is often a retainer problem rather than a plug problem. The Medeco 12029006-24-G3 is the plug itself, a captive Biaxial 6-pin G3 unit for the Maxum Deadbolt. A part like the Corbin Russwin 219F88-8 is a Grade 1 cylinder plug retainer - the piece that holds a plug in its shell - and it belongs to the Corbin Russwin line, so match any retainer to the cylinder brand in the door before ordering a full replacement plug.
10) What finish does the Medeco Maxum cylinder plug come in, and will it match my other door hardware?
Dark Bronze, BHMA finish code 624. It is the only finish offered on this plug, so if your Maxum deadbolts and lever trim are in a bright or satin chrome, the visible plug face will not match. Dark Bronze reads well against oil-rubbed and dark bronze architectural hardware.
11) Does the Medeco 12029006-24-G3 come keyed, or do I have to key it myself?
Plan on a locksmith pinning it. This is a plug for the Maxum deadbolt keyed to the Biaxial G3 keyway, and Biaxial bottom pins have to be both sized and rotated to the bitting, which takes Medeco tooling. If you are adding it to an existing G3 master system, hand it to whoever holds your key records so it comes back on the right change key.
