A cylinder (1) with associated key (6), comprising a stator (2) provided with a longitudinal cavity (3) for accommodating a rotor (4) with a longitudinal recess (5) for the insertion of a coded key (6). The rotor (4) and the stator (2) comprise channels (7), which are substantially aligned and face each other when the cylinder (1) is in the closed configuration, for accommodating respective pins (8), complementary pins (9) and any elastic means (7a). The rotor (4) comprises at least one second passage (10), which is not aligned with respect to the channels (7) and faces, in the closed configuration of the cylinder (1), a corresponding cavity (11) of the stator (2), the passage and the cavity accommodating at least one respective movable peg (12), whose head (13) rests against the blade edge (14) of the key (6) when the key is inserted in the recess (5). The key (6) is provided with suitable contoured regions (15) on its blade edge (14) at the surfaces that face said pegs (12) when inserted in the recess (5). Each peg (12) has its base (16) inside the respective cavity (11) so as to block the rotation of the rotor (4) with respect to the stator (2) when a key (6) lacking the corresponding contoured regions (15) is inserted. |
