Prosero company Romerike Låsservice AS acquires KeyWest Lås og Sikkerhet AS in Norway

2024/02/09

Romerike Låsservice, a Prosero company, today announced its acquisition of KeyWest Lås og Sikkerhet AS, a highly regarded local locksmith firm based in Oslo. This strategic addition will significantly strengthen Romerike Låsservice.

Founded in 2002, KeyWest is a specialist in high-quality security services within advanced lock systems, access control, and door automation. The company is based in a combined shop and service centre in Oslo and has established itself as a leading provider in the aftersales segment. KeyWest is known for its excellent service and efficient working methods in smaller and tailormade projects.

Through the acquisition of KeyWest, which is managed by Stig Roar Punnerud and his team of four associates, Romerike will increase its competence and staffing while also strengthening its products in the aftersales market. In 2023, KeyWest’s turnover amounted to NOK 7.2 million.

Combining KeyWest’s strong customer relationships, focus on aftersales services, and many strategic service agreements with Romerike’s current offering is expected to create significant synergies. Stig Roar and his team will continue to work closely with customers but will now do so as part of the Romerike Låsservice brand.

“This acquisition represents a natural step in our strategic cooperation,” notes Stig Dahlgren, COO of Romerike Låsservice AS. “Our products and services complement each other so well, and now as we join forces, we’ll be taking a major step towards becoming a more all-round partner for all our customers. We extend a warm welcome to Stig Roar and his team. We’re excited about the new opportunities and significant advantages for the team.”

“We’re so pleased to become part of Romerike Låsservice,” says Stig Roar Punnerud, former CEO of KeyWest. “Together, we’ll be able to advance into new markets and improve our customer offering, while we can also maintain the valuable customer relationships that are the foundation of KeyWest’s success. By making the most of our shared strengths, we can be an even better partner to our customers. I look forward to the journey ahead.”
