<p>The cylinder lock comprises a body (10), a cylinder (20), a bush (30), and a key (40) to unlock this lock, characterised in that the keyway has a spiral entrance (31) which allows only the entry of a specialised key (40), and in that the ward mechanisms are arranged around the periphery of the cylinder (20), contrasting with those of a conventional cylinder lock which are arranged on a plane, to protect the lock against being picked by unauthorised persons with a wire or skeleton key, and to prolong the life of the use of such lock.</p> |
