ABSTRACT:
Certain types of key-operated padlocks are provided with warded inserts accessible for key insertion through an opening in the bottom of the padlock body. In the present structure when the proper key is inserted into the warded insert (housed within the padlock body) the cuts in an edge of the key shank match and register with similar cuts or notches in the insert permitting the key to be turned with the specially formed tip of the key engaging a web on the bottom of the plug extension blade within the lock body with special cuts or notches and nodules in and on the key tip engaging companion formations in and on the bottom of the plug extension whereby turning movement of the key will turn the plug extension to the extent necessary to retract certain shackle holding levers and thus release the padlock shackle.
