Medeco 11-0018-26 – Frequently Asked Questions
1) Does the Medeco commercial thumbturn come with a deadbolt or cylinder?
No. The Medeco Commercial Style Thumbturn is the turn piece only, no deadbolt and no cylinder in the box. You buy it either as a replacement for a turn that's been lost or damaged on an existing Medeco Maxum deadbolt, or to complete a new install where you already have the compatible Medeco deadbolt cylinder on hand. If you need the whole lock, order a Maxum deadbolt, not this part.
2) Which Medeco cylinders does this commercial thumbturn work with?
It's built for Medeco M3, Original, and Biaxial captive blade deadbolt cylinders on the Maxum deadbolt platform. Those aren't interchangeable at the order form: you pick either the M3 version or the Original/Biaxial version when you buy. Identify what's in the door before ordering, because an M3 turn is not the same part as the Original/Biaxial turn.
3) I don't know if my Medeco deadbolt is M3 or Biaxial. Does it matter which thumbturn I order?
Yes, it decides which part number you need. The turn is sold in two application versions, one for M3 and one for Original or Biaxial, and the two are ordered separately. Medeco keys and cylinders differ between the Biaxial and M3 generations, so a locksmith pulling the cylinder or reading the key can tell you which platform you're on before you commit. Model reference for the pair is 11-0018 / 11-0092.
4) Can the Medeco thumbturn be taken off so the deadbolt is key-only from both sides?
That's the point of the removable design. The turn stays in the lock for normal day-to-day use, and pulls out when you want the inside to be key-only, which is how people set it up for vacation homes, unoccupied rental units, or a glass-adjacent door where a broken pane would otherwise give someone a turn to reach. Put it back in and the door operates normally from inside again.
5) My Medeco deadbolt turn piece broke off. Can I replace just the turn instead of the whole deadbolt?
Yes, and that's the common repair. The Commercial Style Thumbturn is sold as a standalone component for exactly this, so the deadbolt body, cylinder, and existing keying all stay in the door and nobody has to be re-keyed. Match the application (M3, or Original/Biaxial) to the cylinder already installed and pick the finish that matches the rest of the trim.
6) Will this Medeco thumbturn fit a non-Medeco deadbolt like a Schlage or Kwikset?
No. This turn is machined for Medeco M3, Original, and Biaxial captive blade deadbolt cylinders on the Maxum platform. It's not a universal turn piece and won't mount to another manufacturer's deadbolt. If the door has a different brand of deadbolt, you need that brand's own turn or a full deadbolt replacement.
7) What finishes does the Medeco Commercial Style Thumbturn come in?
Eight finishes, in both the M3 and the Original/Biaxial application: 605 bright brass, 606 satin brass, 609 antique brass, 613 dark bronze oil-rubbed, 619 satin nickel, 624 dark bronze, and 625 bright chrome and 626 satin chrome. If you're matching a turn to existing Medeco trim on the other doors in a building, order the same BHMA finish number that's already on the lock rather than matching by eye, since 613 and 624 both read as dark bronze but are not the same finish.
8) Is this a commercial-grade thumbturn or a residential one?
It's the commercial style turn, machined brass, catalogued by Medeco as commercial trim for the Maxum deadbolt. That said, it gets used on high-security residential entries and multi-tenant buildings just as often as on office doors, because the Maxum platform spans both. The commercial styling is what distinguishes it from Medeco's residential turn shape, so if you're matching the look of turns already installed elsewhere in the building, check which style is on those doors.
9) Can I standardize the same removable thumbturn across a whole apartment building's Medeco deadbolts?
You can, as long as every door is on the same Medeco platform. Order the M3 version for M3 cylinders and the Original/Biaxial version for the older cylinders, and hold one finish number across the property so replacements down the line are a single line item. Buildings with mixed vintages of Medeco deadbolts will need both application versions, so survey the doors before placing a bulk order rather than assuming one part covers the whole fleet.
