The key has a cladding profile (6) formed in a side surface of a shaft (1) and arranged in a longitudinal direction of the shaft. Profile grooves (3) interrupt the cladding profile, and locking recesses are formed in the shaft. An elongated stretched element (5) i.e. pin, is fixed in the shaft. The elongated stretched element is completely arranged within the cladding profile of the shaft and immovably projects into the profile grooves. A symmetry axis of the elongated stretched element is bent relative to a surface of the shaft around an angle.
