Behind PROLOCK's Gold Finish

Every PROLOCK frame passes through several rounds of hand-finishing before it takes its final shape. The body is first machined from a single block of aluminum or steel on a CNC mill, then polished across multiple sanding stages.

Why matte gold?

A glossy gold finish scuffs and shows fingerprints quickly. PROLOCK uses a matte-gold finish with a protective nano-coating that keeps the luxury look while standing up to daily use.

Quality control

Before packaging, every lock is checked for sensor accuracy, mechanical strength, and finish consistency. You can see this finish up close on the flagship PROLOCK PR-700K, or compare it across the rest of the lineup on the products page.
