A Leader in Manufacturing Keys & Key Cutting Machines


Set up by Alejandro Altuna in 1942, starting as a small metal polishing workshop in the town of Mondragón in the Basque region of Spain. Shortly after the company’s inception, the business moved into key manufacturing as this was a flourishing sector in the town. Over the next 20 years, a new generation of the Altuna family drove the company forward through commitment, development and investment, which saw the company grow significantly and become the sector leader in Spain by the 1960s.

Over the last half a century, the company has strategically opened up markets and bases across the globe like North and South America, India and across all of Europe. This growth and development have allowed JMA and the Altuna Group to become the largest producer of keys in Europe and a benchmark worldwide for quality.
