Lockset keyway cover-up mechanism

A lockset keyway cover-up mechanism including a rotor, a rotor case cover, a retainer, magnetic pins, springs and a casing adapted with a key containing an magnetic unlocking part, the key having an unlocking part containing multiples of magnets with its magnetism the same as that of those magnetic pins on the rotor;

• the casing related to a hollow one to cover up the rotor and those members described above, characterized by that:
• the keyway being provided in the rotor case cover on the front face of the rotor and provided with multiples of pinholes irregularly distributed on the case cover to accommodate the springs and those magnetic pins;
• the retainer having provided a through hole in relation to the keyway of the rotor case cover and multiples of insertion hole being provided in relation to those pinholes on the retainer;
• and
• the retainer being provided on the front end of the rotor case cover and covered in position by the casing, the retainer being engaged with its insertion holes to the front face of the rotor case cover and held in position by those magnetic pins in those insertion holes as pushed by the springs, the through hole of the retainer being apart from the keyway, with the unlocking part of the key attached to the retainer, those magnetic pins being rejected by those magnets inside the unlocking part so to clear away from those insertion holes of the retainer for the retainer to engage free rotation, and the through hole of the retainer being overlapped with the keyway.
