Mul-T-Lock is an Israeli lock manufacturer and subsidiary of ASSA ABLOY. The company develops, manufactures and markets high security locks and access control systems globally. Its products and its trademarks are used by professionals, businesses, institutions and consumers.


In 1973, Mul-T-Lock introduced the first-of-its-kind, four-way door lock system. Today, four-way locks based on the original, pioneering concept are still in use today all over the world.[citation needed]

In 1976, the success of the four-way lock spread worldwide as marketing efforts expanded globally. With the company’s rapid growth, Mul-T-Lock expanded its manufacturing plant and by 1982, the company had greatly increased its product line to include a wide range of High Security cylinders, locks and accessories, steel doors and vehicle protection products. To support the company’s growth and reach, in 1987, Mul-T-Lock launched its first sales subsidiary in the US, and open a second manufacturing plant in Israel. In the years that followed, Mul-T-Lock further expanded its global reach, with the establishment of European subsidiaries and penetration into the East Europe and Asia Pacific market.[citation needed]

Mul-T-Lock also began to manufacture automatic key-cutting and assembly machines. In combination with custom-developed software, these key-cutting machines now allow locksmiths to create complex key systems.

Mul-T-Lock was acquired by ASSA ABLOY in 2000. Today, the company has 13 selling units globally and a distribution network present in 70 countries.[citation needed]

International pressure forced Mul-T-Lock to relocate from an Israeli settlement in the occupied West Bank to within pre-1967 Israeli territory.[1]
