A key elevator is a surgical instrument primarily used in procedures that require the dissection and separation of tissue. Its design typically features a narrow, flat blade that allows the surgeon to carefully lift and separate layers of tissue without causing excessive damage or trauma, which is crucial during surgical procedures. The tool's functionality enables precise manipulation, making it especially valuable in tasks such as preparing an area for further surgical interventions or clearing a field of view in minimally invasive surgery.

The other options do not accurately describe the key elevator's purpose. Removing hardware is associated with extraction tools, reaming the acetabulum relates to instruments specifically designed for shaping the hip joint, and holding a bone in place pertains to clamps or bone holding forceps, which serve different functions in surgical practices. Understanding these distinctions highlights the specialized role that a key elevator plays in surgical environments.
