Dormakaba 34021-04-01 – Frequently Asked Questions

1) What exactly is the Dormakaba 34021-04-01 part, the lock or just the housing?
It's the cylinder housing only, not a complete lock and not a cylinder. The 34021-04-01 is the component that holds and retains the cylinder in a compatible Dormakaba mechanical lock body, sold as a replacement part so a worn or damaged housing can be swapped without buying a whole new lock assembly. You reuse your existing cylinder and lock body.
2) Is the Kaba Ilco R2800 housing a substitute for the Dormakaba 34021-04-01 cylinder housing?
They are not interchangeable parts. The Dormakaba 34021-04-01 is a replacement cylinder housing supplied in a 606 Satin Brass finish for compatible Dormakaba mechanical lock bodies, so it is ordered when the existing Dormakaba lock is being kept and only the housing is being renewed. The Kaba Ilco R2800 Series is a small format interchangeable core convertible housing, meaning it is selected to accept an SFIC core rather than to restore a specific Dormakaba lock assembly. Choose the 34021-04-01 for a brand-matched Dormakaba repair and the R2800 when the goal is putting an SFIC core into the opening.
3) I need a cylinder housing for a mortise lock prepped for a large format IC core - what should I use?
For a mortise application taking a large format interchangeable core in the Schlage size, the Kaba Ilco S26506 is the housing built for that function; it is catalogued with a mortise product function. The Dormakaba 34021-04-01 is a different animal - it is an OEM cylinder housing replacement for compatible Dormakaba mechanical lock systems, matched to that lock family rather than sized around an LFIC core, and it comes in 606 Satin Brass.
4) What finish does the Dormakaba 34021-04-01 cylinder housing come in?
One finish only: 606 Satin Brass, which Dormakaba also designates NL. It's factory applied, so it matches other Satin Brass Dormakaba trim on the same opening. If your building is standardized on a satin chrome or bronze finish, this part number is the wrong one to order.
5) My Dormakaba lock housing is worn and the cylinder wobbles. Do I have to replace the whole lock?
Not necessarily. The 34021-04-01 is sold specifically so a worn or damaged cylinder housing can be replaced on its own, keeping the existing lock body in service and cutting downtime. Confirm the housing part number stamped on your current component is 34021-04-01 and that the opening is Satin Brass before ordering.
6) What is the difference between the small format and large format IC core housings offered alongside the Dormakaba 34021-04-01?
The Kaba Ilco R2800 Series is a convertible housing for small format interchangeable cores, while the Kaba Ilco S26506 is a mortise housing for large format interchangeable cores in the Schlage size. Core format drives the choice: match the housing to the core family already keyed into the facility. Neither is a stand-in for the Dormakaba 34021-04-01, which is a brand-specific cylinder housing replacement part for commercial Dormakaba mechanical lock assemblies.
7) We are standardizing keying across a building - is the Dormakaba 34021-04-01 the right part, or should we move to an IC core housing?
If the plan is to bring every opening onto one interchangeable core system so cores can be swapped without pulling locks, an IC core convertible housing is the direction: the Kaba Ilco R2800 Series covers small format IC cores and the Kaba Ilco S26506 covers large format IC cores in the Schlage size for mortise locks. The Dormakaba 34021-04-01 serves the other case - keeping the existing Dormakaba mechanical locks in service and replacing a worn or damaged housing with the genuine OEM component in 606 Satin Brass, without replacing the full lock assembly.
8) Is this housing rated for commercial door traffic or is it a residential part?
Commercial. Dormakaba lists the 34021-04-01 as a commercial-grade component for mechanical lock applications, and it's used in office buildings, schools, healthcare, retail, warehouse, multi-tenant residential and government facilities. For an MRO buyer standardizing spare parts across a portfolio, it is a stocking item on the commercial side.
