ABSTRACT:
A lock has a cylinder formed with a keyhole and rotatable in a housing. At least one tumbler is displaceable into the keyhole into engagement with a bit of a key which can position the segments of the tumbler so as to allow rotation of the cylinder in the housing. In addition the key is provided with a magnet that can coact with a magnetic rotor to rotate this magnet into a position that aligns a notch on the magnet or a control wheel controlled thereby with a retaining element. The housing is formed at its back end with a recess in which one end of the retaining element is urged by a weak spring. Only when the notches on the rotors are aligned with tabs on the retaining element can this element be displaced out of the recess in the housing and allow rotation of the cylinder relative to the housing.
