Dormakaba 203000-03-01 – Frequently Asked Questions

1) What exactly is the Dormakaba 203000-03-01, the lock or just a part of it?
It is the front lock housing only, a cylinder housing that holds and aligns the lock cylinder inside a Dormakaba mechanical lock assembly. It is sold as a replacement part, not a complete lockset, so you keep your existing cylinder, trim and latching and swap the housing.
2) Will the Dormakaba 203000-03-01 front housing fit any brand of lock?
No. It is a Dormakaba OEM part made to Dormakaba specifications and fits compatible Dormakaba mechanical lock assemblies. If the lock on the door is another brand, this housing is the wrong part, and for a generic interchangeable core housing you would look at something like the Kaba Ilco R2800 Series small format IC core convertible housing instead.
3) What should I order if I need a cylinder housing that takes a large format interchangeable core instead of a Dormakaba front lock housing?
Look at the Kaba Ilco S26506, a large format IC core convertible housing in Schlage size with a mortise product function. It is the choice when the opening is being keyed into a large format IC system on a mortise lock. The Dormakaba 203000-03-01 front lock housing is a different kind of part: a genuine replacement component for a compatible Dormakaba mechanical lock assembly, offered in a 605 Bright Brass finish.
4) Can a Kaba Ilco R2800 convertible housing be used in place of the Dormakaba 203000-03-01 front lock housing?
No. The Dormakaba 203000-03-01 is a front lock housing supplied as a genuine replacement part for compatible Dormakaba mechanical lock assemblies, where it supports and aligns the lock cylinder. The Kaba Ilco R2800 Series is a small format interchangeable core convertible housing, which is a cylinder housing built to accept an SFIC core rather than a service replacement for a Dormakaba lock body. If the goal is to restore an existing Dormakaba lock to original fitment, the 203000-03-01 is the part that does it; the R2800 is for openings being set up on a small format IC keying system.
5) What finish does the 203000-03-01 lock housing come in?
One finish only: 605 Bright Brass, a polished brass. If the rest of the trim on the opening is satin chrome or oil rubbed bronze, this housing will not match and you would want the same part in the corresponding finish code.
6) I need to standardize repair parts across a building of Dormakaba locks. What do I order for the front housing?
Order by the Dormakaba model number 203000-03-01 and specify the 605 Bright Brass finish. Because it is a genuine OEM part built to the original specification, the fit and finish match across openings using the same lock family, which is what keeps a facility's hardware consistent as housings get replaced one at a time.
7) My Dormakaba cylinder is loose or misaligned in the door. Is the front housing the part to replace?
That is what this part addresses. The front lock housing provides the structural support and alignment for the cylinder within the assembly, so a housing that is worn, cracked or sprung is a common cause of a cylinder that sits loose or binds. Replacing it restores the original fit without disturbing the cylinder or keying.
8) Is the difference between the Kaba Ilco R2800 and S26506 housings relevant when sourcing a Dormakaba 203000-03-01?
They differ from each other by core format: the R2800 Series is a small format IC core convertible housing, while the S26506 is a large format IC core convertible housing in Schlage size for mortise applications. Neither choice affects the Dormakaba 203000-03-01, which is a front lock housing manufactured to Dormakaba specifications for compatible Dormakaba mechanical lock systems rather than an IC core conversion part.
9) Is this housing rated for commercial door traffic or is it a residential part?
Commercial. The 203000-03-01 is classed as a commercial door hardware component and is used in offices, schools, healthcare, retail, warehouses, multi-tenant residential and government buildings, so it is the part to specify for high-use openings rather than a light-duty residential substitute.
