Abstract
A lock configured to be operated by a key, which includes a key shank, which at least in a part of its axial length includes a profile which is closed or semi-closed to define at least one cavity including a key coding. The lock includes a plug for receiving the key shank. The plug is rotatable with respect to a housing in the unlocked state of the lock and includes a keyway, which is defined by a predetermined geometry. At least one keyway shaping element is provided, which is formed separate from the plug and is fixed to the plug such that it is immovable relative to the plug when the key shank is inserted into the plug. A protruding portion of the at least one keyway shaping element protrudes into the keyway to redefine its geometry.
