DormaKaba 74832-000-01 Combination Chamber — Genuine 5000 Series Lock Replacement Part

The DormaKaba 74832-000-01 Combination Chamber is an OEM replacement component engineered specifically for the DormaKaba 5000 Series commercial lockset line. When a combination chamber wears, cracks, or fails, replacing it with the correct factory part restores the lock mechanism to full operating specification — avoiding a costly full-lock replacement and keeping the door hardware assembly in its original, tested configuration.

This part is identified by manufacturer part number 74832-000-01. Facility managers, commercial locksmiths, and maintenance contractors sourcing 5000 Series lock parts should verify this part number against the existing hardware before ordering to confirm compatibility.

What Is a Combination Chamber?

In a cylindrical or mortise-style lock assembly, the combination chamber (also referred to as a combination housing or plug housing in some lines) is the internal component that integrates the cylinder plug seating and the latch/deadbolt actuating mechanism. It is a precision-machined part that must be dimensionally accurate to maintain correct cylinder engagement, smooth lever or knob operation, and reliable latch retraction. Using a non-OEM substitute risks misalignment, premature wear, or functional failure — making a genuine manufacturer replacement the recommended choice for commercial-grade installations.

Key Benefits

• OEM accuracy — manufactured to DormaKaba factory tolerances for the 5000 Series platform
• Restores lock function — brings a worn or damaged assembly back to original specification without full lockset replacement
• Cost-effective repair path — part-level service avoids unnecessary complete hardware changeout
• Correct fit confidence — part number 74832-000-01 is the direct manufacturer reference for this component

Typical Applications

• Repair and restoration of DormaKaba 5000 Series cylindrical locksets in commercial buildings
• Preventive maintenance programs for facility hardware inventories
• Commercial locksmith service calls requiring OEM 5000 Series internal components
• Institutional, educational, healthcare, and office facilities with existing 5000 Series door hardware
