Multlock

Mul-T-Lock (sometimes typed “Multlock”) is an Israeli high-security locking brand best known for high-security cylinders, patented key systems, and mechanical + electromechanical access solutions aimed at locksmiths, institutions, and commercial sites where key control and attack resistance actually matter.

• Founded: 1973 in Israel (Mul-T-Lock states “founded in Israel in 1973”). 

• Ownership: Fully owned by ASSA ABLOY; ASSA ABLOY completed the acquisition on 31 Jan 2000 (consolidated from 1 Feb 2000). 

What it’s known for (the “why you’d stock it” bit)

• High-security mechanical cylinders & keys with strong key-control stories (patented platforms, restricted profiles, etc.). 

• Electromechanical upgrades (turning “just a cylinder” into managed access) alongside classic mechanical master-keying for bigger sites. 

• A big “locksmith channel” identity: Mul-T-Lock explicitly positions itself as a locksmiths’ preferred partner, with authorised centres and support tooling. 

Tiny lore nugget

Their early growth story is tied to a “multi-directional / four-way” locking concept that helped launch the brand internationally, and later expansion into more advanced cylinder platforms.
