Herman Miller Control Keys are specialized service keys designed to install, remove, and manage lock cores in Herman Miller office furniture.

These control keys allow lock cores to be safely removed or replaced without damaging furniture, supporting efficient re-keying, lock core replacement, and security standardization across offices and workstations. They are commonly used with Herman Miller lock core systems, including the popular UM Series and other compatible lock series.

Using genuine Herman Miller control keys ensures proper fit, smooth operation, and preserves the overall security integrity and longevity of your office furniture investment.
