Medeco 1202900T-12-DL – Frequently Asked Questions

1) What exactly comes with the Medeco 1202900T-12-DL, a complete cylinder or just the plug?
Just the plug. The 1202900T-12-DL is the cylinder plug only for a Medeco Maxum deadbolt cylinder, not a full cylinder and not a complete deadbolt. If you need a whole cylinder or a new lock body, this part will not serve on its own. It is sold as a replacement part for professional installation into an existing Maxum cylinder housing.
2) Will this Medeco plug work with my existing keys?
Only if your system is on the M3 platform with a DL keyway. The 1202900T-12-DL is a captive M3 6-pin plug cut for the DL keyway, so it keys into a Medeco M3 DL system. A different Medeco keyway, or an older Biaxial or Original system, will not accept these keys. Confirm the keyway stamp on your current cylinder before ordering, and expect to have the plug pinned to your key by a locksmith with M3 key control authorization.
3) I need a plug for a mortise cylinder, not a deadbolt. What should I use instead of the Medeco 1202900T-12-DL?
The Medeco 1202900T-12-DL is engineered specifically as a replacement plug for Medeco Maxum deadbolt cylinders, so it is not the part for a mortise cylinder body. For mortise applications, the Corbin Russwin 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs, the two differing by keyway designation (D2 and L4). Choose the one matching the keyway already in service on the opening.
4) Is the Corbin Russwin 253K66 rim cylinder plug an equivalent to the Medeco 1202900T-12-DL?
No. The Medeco 1202900T-12-DL is a cylinder plug built as a replacement component for the Medeco Maxum deadbolt, using a captive M3 6-pin configuration with a DL keyway. The Corbin Russwin 253K66 is a 3000 Rim Cylinder Plug, so it belongs to a rim cylinder rather than a deadbolt cylinder and carries the Corbin Russwin keyway system rather than the Medeco M3 platform. A locksmith keying to a restricted Medeco system would stay with the Medeco plug; the 253K66 serves a rim cylinder application.
5) What does the captive M3 configuration mean for a locksmith servicing this plug?
Captive means the plug is retained in the cylinder housing rather than being freely removable, so servicing follows Medeco's captive-plug procedure rather than a simple plug pull. It is a 6-pin M3 build, which brings the M3 angled-cut pin geometry and the sidebar element into play when pinning. Plan the job as a bench operation, not a quick swap in the door.
6) Is this Medeco plug right for a commercial building or is it a residential part?
It is specified as commercial. The Maxum deadbolt plug is aimed at facilities running restricted key control, offices, schools, healthcare, government buildings, multi-tenant properties, retail with master key systems, and warehouses. A property manager standardizing a building on M3 DL can re-plug existing Maxum deadbolts with this part instead of replacing the whole lock.
7) What is the difference between the Corbin Russwin 121K11-D2 and 121K11-L4 mortise plugs?
Both are Grade 1 1000 Series mortise cylinder plugs from Corbin Russwin, supplied as plug-only components. The difference is the keyway designation carried in the part number: D2 on the 121K11-D2 and L4 on the 121K11-L4. Match the suffix to the keyway of the key system already installed at the facility.
8) For a facility standardizing on restricted key control, how does the Medeco 1202900T-12-DL compare to the Corbin Russwin plug options?
The Medeco 1202900T-12-DL is built on the Medeco M3 platform with a 6-pin captive design and DL keyway, which supports restricted key duplication and master key control on Maxum deadbolts, and it is designated a commercial replacement part. The Corbin Russwin alternatives sit in their own systems: the 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs and the 253K66 is a 3000 Rim Cylinder Plug. Standardizing means picking one manufacturer's keying platform and cylinder type per opening group rather than mixing them.
9) What finish is the Medeco 1202900T-12-DL cylinder plug?
Satin bronze clear coated, BHMA finish 612. That is the only finish this plug is built in. It reads as a warm brown bronze and sits alongside 612 trim and deadbolt collars; if your existing Maxum hardware is satin chrome 626 or bright brass 605, the plug face will not match visually even though it functions the same.
10) Do I need a plug retainer with this Medeco Maxum plug?
No separate retainer is called for here, because the plug is a captive design that is held in the cylinder housing by its own configuration. Retainers are a Corbin Russwin style of part, for example the 219F88-8 Grade 1 cylinder plug retainer, and that part belongs to Corbin Russwin cylinders, not to a Medeco Maxum.
