TrioVing is a Norwegian brand of locks and security equipment, now owned by the Swedish lock group Assa Abloy.[1]

The company was formed in 1971, when Christiania Spigerverk combined two lock makers it had acquired: Trio Fabrikker of Oslo, whose origins reached back to the Christiania Dørvriderfabrik of 1864, and the Moss firm Wilhelm Rosenvinge, maker of the "Ving" brand.[2][3] The headquarters was placed at the Ving plant in Moss, and the company grew into the largest lock manufacturer in the Nordic region, known internationally for the plastic-card VingCard system that became a standard in hotels and cruise ships,[2] and domestically for its "Firmus" cylinder keys.[4]

TrioVing later came under Elkem, then Finnish ownership, and from 1994 belonged to the newly merged Assa Abloy group; it absorbed its sister company Grorud Industrier in 1999 and became a wholly owned Assa Abloy subsidiary in 2004.[2] Production was moved out of Moss to Ski in 2014, and the TrioVing name has been retained as an Assa Abloy trademark.[3]
