Mul-T-Lock  History  in  Israel :
In  the  early 1973 :
       Two  young  inventors  were  approached  by  a  lady  who  had  been  repeatedly  burgled  and  desperately  wanted  a  solution.   To  meet  the  brief,   the  entrepreneurs  CREATED  A  UNIQUE  FOUR-WAY  LOCK ;   Comparable  to  those  found  on  airline  doors  at  the  time.  
In  the  late 1975 :
      From  this  they  began  to  offer  a  full  service,   which  involved  taking  down  the  existing  door  leaf,   upgrading  the  security ;      By  installing  one  of  their  newly  designed  four–way  locks  and  then re-hanging  the  door.   The  pair  went  into  partnership  and  developed  a  significant  market  share,   upgrading  all  the  timber  doors  to  steel  and  incorporating  the  then  patented  four- way  lock.
In  the  early 1977 :
      Mul-T-Lock  started  developing  patented  key  cylinder  systems,     after  identifying  the  cylinder  as  the  weak  point  in  the  door  set. 
In  the  early 1982 :
      Mul-T-Lock  had  greatly  expanded  its  product  line  to  include  a  wide  range  of  cylinders,   locks  and  High  Security  accessories.
