A cylinder lock (1 ) and an associated key (2), the lock (1 ) comprising a fixed body (3) and a plug (4), which is accommodated within a respective cavity (5) of the body (3) and can rotate with respect to the body (3). The plug (4) comprises a substantially longitudinal compartment (6) for the functional accommodation of a key (2) which comprises a grip portion (21 ) from which an elongated body (22) extends which is provided with coding grooves and protrusions (23) on its outer surface. Between the plug (4) and the body (3) there are respective accommodation channels for translating coding elements, which open onto the substantially longitudinal compartment (6). The plug (4) comprises at least one auxiliary duct (7), which faces the substantially longitudinal compartment (6) and extends at least partially in the body (3), for the sliding accommodation of at least one coding unit (9) that is constituted by at least one pin (10) and at least one conical portion (1 1). The conical portion (1 1) is fitted at least partially on a first end (12) of the pin (10). The second end (13) of the pin (10), which faces the substantially longitudinal compartment (6), has a shape and dimensions that are complementary to those of a depression (16) of the head (14) of a movable pad (15) that is accommodated elastically within a recess (24) of the key (2), against which it abuts in the configuration for use, being at least partially accommodated in said depression (16) in the configuration for use. |
