Medeco 1202900T-18-DL – Frequently Asked Questions

1) Can I use this Medeco plug on my existing DL keyway master key system?
Yes. It is cut for the Medeco DL keyway, so it integrates with an established DL keyway system and master key hierarchy. The 6-pin tumbler arrangement gives the bitting range needed for master keying across a building. Your locksmith pins it to your system.
2) Do I have to replace the whole Medeco cylinder, or can I just swap the plug?
Just the plug. The 1202900T-18-DL is a replacement part that restores a Maxum deadbolt cylinder without replacing the full cylinder, which is why locksmiths and in-house maintenance teams stock it for worn or damaged plugs.
3) Can a Corbin Russwin 121K11 cylinder plug be used in place of the Medeco 1202900T-18-DL Maxum Deadbolt plug?
No. The Medeco 1202900T-18-DL is a captive M3 6-pin plug cut for the Medeco DL keyway and built specifically for the Maxum Deadbolt cylinder, so it only accepts Medeco DL keys and only drops into that Maxum housing. The Corbin Russwin 121K11-D2 and 121K11-L4 are plug-only parts for the Corbin Russwin 1000 Series mortise cylinder and carry their own keyway designations (D2 and L4). Keyway, pin stack, and housing all differ, so the two are not interchangeable in either direction.
4) What does the captive plug design on this Medeco cylinder plug actually do?
A captive plug is retained inside the cylinder housing, so it cannot be pulled out without the proper tools. That blocks plug-removal attacks, and it pairs with the M3 pick and drill resistance for high-security openings like government, healthcare, and education facilities.
5) Is there a cylinder plug like this for Corbin Russwin locks instead of Medeco?
The Medeco plug is Maxum-specific and will not go into a Corbin Russwin cylinder. For Corbin Russwin, the 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs (plug only, in D2 and L4 keyways), and the 253K66 is the 3000 Series rim cylinder plug. If you only need the retainer rather than the plug, that is the 219F88-8.
6) Is a cylinder plug retainer the same thing as the Medeco 1202900T-18-DL cylinder plug?
No, they are different parts. The Medeco 1202900T-18-DL is the keyed plug itself - the rotating barrel that holds the pin stack and accepts the DL keyway key. The Corbin Russwin 219F88-8 is a cylinder plug retainer, the small component that holds a plug in its housing. If a Maxum Deadbolt plug is worn or damaged, the plug is the replacement part; a retainer will not restore key operation.
7) For a facility standardized on Medeco DL keys, why choose the 1202900T-18-DL over a Corbin Russwin plug?
Key control is the deciding factor. The 1202900T-18-DL carries the Medeco DL keyway with M3 technology and a 6-pin stack, so it folds straight into an existing Medeco DL master key hierarchy on a Maxum Deadbolt without reissuing keys. Corbin Russwin plugs such as the 121K11-D2 and 253K66 operate on Corbin Russwin keyways and cylinder platforms, which would mean a separate key system for that door.
8) What finish does the Medeco 1202900T-18-DL come in, and will it match my other hardware?
One finish only: 618 Bright Nickel. It is a polished, corrosion-resistant look. If your other Maxum deadbolts are in a brass or bronze finish, the visible plug face will not match, so order accordingly.
9) Is this Medeco plug rated for commercial use or is it a residential part?
Commercial. It is classified as a commercial-grade replacement part, and the typical uses are office buildings, schools, hospitals, municipal buildings, retail, industrial plants, and multi-tenant residential running commercial deadbolt hardware.
