Medeco 12029006-19-G3 – Frequently Asked Questions

1) What exactly is the Medeco 12029006-19-G3 and what lock does it go into?
It's a replacement cylinder plug, the keyed plug assembly that drops into a Medeco Maxum Deadbolt cylinder. It comes as a captive 6-pin Biaxial plug cut for the G3 keyway in a Satin Nickel (619) finish. It is not a complete cylinder and not a complete deadbolt, so you're rebuilding or rekeying an existing Maxum, not replacing the lock.
2) Will a G3 plug work with the keys already on my Medeco system?
Only if your existing system is a Medeco Biaxial system on the G3 keyway. G3 is a restricted keyway, so keys are cut only by authorized Medeco dealers, and a plug in a different Medeco keyway will not accept G3 keys. If your building is keyed on another Medeco keyway or on Medeco3, order the plug in that keyway instead so the new cylinder stays on your existing master key system.
3) Can I use this Medeco plug in a rim or mortise cylinder instead of a deadbolt?
No. This plug is built to OEM spec for Medeco Maxum Deadbolt cylinders and won't serve as a rim or mortise cylinder plug. For a rim cylinder plug, the Corbin Russwin 253K66 3000 Rim Cylinder Plug is the rim-format part; for mortise, Corbin Russwin's 121K11 1000 Series mortise cylinder plug-only is offered in D2 and L4 keyways. Those are Corbin Russwin keyways, not Medeco, so they won't run on your Medeco keys.
4) Can a Corbin Russwin 253K66 rim cylinder plug be used in place of a Medeco 12029006-19-G3?
No. The Medeco 12029006-19-G3 is a captive Biaxial 6-pin plug built to OEM specification for the Medeco Maxum Deadbolt cylinder, with the G3 restricted keyway. The Corbin Russwin 253K66 is a 3000 Rim Cylinder Plug, so it belongs to a rim cylinder of a different make and does not fit a Maxum deadbolt cylinder body or accept Medeco Biaxial angled-and-elevated keys. Plugs are keyway- and platform-specific; keep the Medeco part in a Medeco Maxum opening.
5) If the opening uses a mortise cylinder rather than a Maxum deadbolt, what plug applies instead?
The Medeco 12029006-19-G3 is a deadbolt part - a captive 6-pin plug for the Medeco Maxum Deadbolt. For a Corbin Russwin 1000 Series mortise cylinder, the plug-only parts are the 121K11-D2 and 121K11-L4, both Grade 1 1000 Series mortise cylinder plugs, which differ from each other by keyway designation (D2 versus L4). Match the plug to the cylinder family already in the door, then to its keyway.
6) Does the 12029006-19-G3 plug come keyed and pinned, or do I have to pin it myself?
It is a 6-pin Biaxial plug for the Maxum Deadbolt, and Biaxial pinning requires bottom pins cut at specific angles and elevations to match your key. Plan on a locksmith with Medeco pin kits and the authorization to order G3 keys and blanks. This is not a hardware-store rekey.
7) What does the captive plug design mean for servicing a Maxum deadbolt?
Captive means the plug is retained in the cylinder housing rather than pulling free on its own, so it stays put during service and reassembly of the Maxum. Practically, it changes how you take the cylinder apart compared with a standard removable plug, and it's the reason a Maxum needs a plug ordered specifically as captive.
8) Why replace just the plug instead of the whole Medeco cylinder?
Swapping the plug keeps the existing Maxum cylinder housing and trim in place and changes only the keyed core, which is the usual move after a key compromise or a tenant turnover on a high-security opening. Because it's a genuine Medeco part made to OEM tolerances, the Biaxial pick resistance and key control of the original install carry over.
9) If I'm standardizing a whole building on Medeco, does ordering plugs like this keep everything on one key system?
Yes, as long as every opening uses the same keyway. Order all plugs in G3 and the six-pin Biaxial format gives you enough combinations to build masters, sub-masters, and change keys across the building. Mixing keyways across floors is what breaks a master key program, so pick one keyway and hold to it, including on spares kept for service.
10) Is the Corbin Russwin 219F88-8 an alternative to the Medeco 12029006-19-G3 plug?
They do different jobs. The 12029006-19-G3 is the plug itself - the rotating pin-tumbler core that carries the Biaxial 6-pin stack and G3 keyway in a Maxum Deadbolt cylinder. The Corbin Russwin 219F88-8 is a Grade 1 Cylinder Plug Retainer, the piece that holds a plug in place rather than the plug. If the key turns but the plug is loose or backing out, a retainer is the part in question; if the keying or keyway is changing, the plug is.
11) For a facility standardizing on restricted key control, how does the Medeco 12029006-19-G3 differ from the Corbin Russwin 121K11 mortise plugs?
The Medeco 12029006-19-G3 uses the G3 restricted keyway with Biaxial pinning, so key cutting requires angles and elevations and duplication is limited to authorized Medeco dealers - that is the basis of the key control program. The Corbin Russwin 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs, identified by their own D2 and L4 keyway designations and fitted to mortise cylinders. A single-keyway program means choosing one platform; the Medeco part keeps a Maxum deadbolt inside a Medeco Biaxial system.
12) Is the Satin Nickel finish on this plug going to match my other door hardware?
The finish code is 619, Satin Nickel, and it's the only finish this plug is offered in. On a deadbolt the plug face is the visible ring around the keyway, so if your Maxum trim is a brass or bronze finish the plug face will read as a different tone. Match the plug finish to the deadbolt collar, not to the lever on the door.
13) Is this part suitable for a commercial building or is it residential-grade?
Medeco classifies the 12029006-19-G3 as commercial. It's the part facilities use in offices, healthcare, schools, and government buildings that run restricted-keyway master key programs, and it also gets used on high-security residential deadbolts where the same key control applies.
14) Two Corbin Russwin 121K11 plugs are listed with different suffixes - what decides which one, and does the same logic apply to the Medeco plug?
Yes, the same logic applies. The Corbin Russwin 121K11-D2 and 121K11-L4 are both Grade 1 1000 Series mortise cylinder plugs; the suffix is the keyway, so the existing system dictates the choice. On the Medeco side, the 12029006-19-G3 carries the G3 keyway and a 19 Satin Nickel finish, offered in 619 Satin Nickel. Order the plug whose keyway matches the keys already issued, or the cylinder will be rekeyed to nothing usable.
