Abloy is a Finnish lock manufacturer that produces medium and high security padlocks, lock cylinders, and electronic locks. Abloy is one of the most well-known high-security lock manufacturers around the world. They are best known for their disc-detainer lock designs. Abloy products are widely used in padlocks, vending machines, and many high-security installations. The Abloy CY436T key-in-knob cylinder with Protec2 key system is UL 437 listed.[1]


The founding of Abloy dates back to 1907, when Emil Henriksson of Helsinki, Finland designed the first disc-detainer lock. It was patented in 1919 with the name "Henriksson’s Patent Lock". Industrial production of the locks began in 1919 and "Ab Låsfabriken - Lukkotehdas Oy" was founded in Helsinki. Later, the company name was shortened to Ab Lukko Oy and the trademark ABLOY was registered.[2]

Kone & Siltarakennus aquired Abloy in 1923. Later in 1936, Abloy joined the Wärtsilä Group, the largest industrial conglomerate in Finland.[3] The factory moved to Joensuu, Finland in 1968. Abloy acquired TrioVing and VingCard in 1983. IKON was purchased in 1989.[4]

Merging with ASSA AB on November 7, 1994, ASSA-Abloy was formed, consolidating the Nordic market. “The agreements between the parties are based on a transaction between equals, where no buyer or seller is specified.”[5]
