Dormakaba 74425-26D-01 – Frequently Asked Questions

1) What exactly is the Dormakaba 74425 part, the whole lock or just the housing?
It's a housing, not a lock. The 74425 is a cylinder housing with an integrated cylinder guard that encases and aligns the lock cylinder within the lock body of a compatible Dormakaba mechanical lock assembly. You are not getting a cylinder, a key, or a latch with it. Order it when the existing housing or guard is damaged and the rest of the lock is still serviceable.
2) What is the correct Dormakaba part number to order for the satin chrome lock housing?
The model to quote is 74425-26D-01, the satin chrome version of the Dormakaba 74425 lock housing with cylinder guard. On the finish line it's listed as 626 satin chrome, which is the same finish 26D refers to in older BHMA notation.
3) Can I use this housing on a non-Dormakaba lock, like a Schlage or Sargent mortise lock?
No. The 74425 is a direct replacement part for compatible Dormakaba lock assemblies only, and the fit is specific to that lock body geometry. If you're working on another brand's lock, source the housing from that manufacturer's parts list instead of adapting this one.
4) Is the Kaba Ilco R2800 housing an equivalent replacement for the Dormakaba 74425 cylinder housing?
No. The Dormakaba 74425-26D-01 is a lock housing with an integrated cylinder guard, supplied as a replacement part for compatible Dormakaba mechanical lock assemblies in a satin chrome finish. The Kaba Ilco R2800 is a small format interchangeable core convertible housing, meaning it is built to accept an SFIC core rather than to serve as a service replacement enclosure for an existing Dormakaba lock body. If the opening uses SFIC cores and you are converting the cylinder platform, the R2800 is the part to look at; if you are restoring a Dormakaba lock assembly to its original configuration, the 74425 is the direct replacement.
5) Will the 74425 housing match the rest of my satin chrome door hardware?
Satin chrome is the only finish this housing is built in, listed as 626 satin chrome (26D). It's a low sheen, corrosion resistant factory finish that sits alongside most commercial levers, pulls and closers specified in 626. If your openings are standardized on bright brass or oil rubbed bronze, this part will not blend in.
6) Is the Dormakaba 74425 cylinder housing rated for commercial traffic or is it a residential part?
It's a commercial part. Dormakaba builds the 74425 to its commercial quality standards for door hardware in office buildings, schools, hospitals, retail, warehouses, multi-tenant residential and government facilities. Property managers replacing hardware in a high traffic corridor are within its intended use.
7) Does the cylinder guard on the 74425 actually add security, or is it just a trim ring?
It's a functional guard, not cosmetic trim. The guard is integrated into the housing and is there to resist tampering and forced entry attempts at the cylinder, which is the usual attack point on a mechanical lock. It works by protecting the cylinder that's already in the lock body, so it does not change the keying or the lock's function.
8) My tenant's key still works but the lock face is chewed up, do I need a whole new lockset?
Often not. If the cylinder still turns and the lock functions, replacing the housing and cylinder guard restores the protected enclosure without pulling the whole lockset off the door. That's the service case the 74425 was built for: keep the existing Dormakaba lock assembly and swap the damaged component, which also keeps the keying untouched.
9) For a commercial building standardizing on Dormakaba locks, which housing keeps the existing hardware intact?
The Dormakaba 74425-26D-01 does. It is a commercial-grade replacement lock housing with a built-in cylinder guard, finished in satin chrome to coordinate with existing commercial hardware, and is designed to encase and align the cylinder within the lock body of compatible Dormakaba assemblies. Choosing it keeps the original lock platform and keying in place. The Kaba Ilco alternatives, the R2800 small format IC core convertible housing and the S26506 large format IC core convertible housing, are conversion housings that move the opening onto an interchangeable core system instead.
