A lock key comprises a key blank ( 20 ) that has a gripping part ( 20 a) and a key bit part ( 20 b). A circuit board ( 34 ) that has mounted thereon electric circuits and a key contact part ( 35 ) connected electrically to the electric circuits are accommodated in a circuit board cradle ( 30 ) made of electrically non-conductive material. The circuit board cradle is fitted to the key blank. The placement of a circuit board and electric contact conductor in an electrically non-conductive material makes possible rational manufacture of the arrangement. Because the circuit board cradle made of electrically non-conductive material can be fixated in the key blank it is possible to position the electric contact conductor precisely, thereby ensuring a reliable electric contact function. |
