ABSTRACT:
A device and method are provided for magnetizing a control magnet housed in a cylinder of an ignition lock. The cylinder is placed in a cylinder receipt member and orientated therein so that the magnet is aligned in a predetermined position. The control magnet is then saturated with a first saturating magnetic charge. The control magnet is then calibrated to a predetermined magnetic level by one or more calibrating magnetic charges, opposite in polarity to the saturating magnetic charge. The control magnet may then be checked for predetermined magnetic characteristics.
