Mul-T-Lock is an Israeli company that develops and sells padlocks, combination locks, and related security products.

[3] Mul-T-Lock launched the Interactive patented platform in 1992 and expanded with new European selling units and entered the Asia Pacific market.

[citation needed] In 2009, Mul-T-Lock introduced the SMARTair access control system following the launch of CLIQ - electromechanical locking solution.

[5] In 2020, Mul-T-Lock adopted a new scalable naming system for its advanced patented mechanical platforms to facilitate recognition amongst end-user.

Consequently, each of the patented mechanical platforms was renamed, and the Mul-T-Lock brand was integrated and assigned a role within each new name.
