Abstract: A sidebar ignition lock is provided with improved anti-tampering features. The ignition lock includes a cylinder extending along a longitudinal axis and rotatably supported within a sleeve. The tumblers are maintained entirely within the diameter of the cylinder to prevent possible picking of the lock. A knob is provided to prevent access to the area between the outer surface of the cylinder and the inner surface of the sleeve. When the cylinder is received within the sleeve, the knob is maintained on the cylinder head by a retaining member extending from the sleeve. The sidebar ignition lock further includes a roller ball detent to prevent over rotation of the cylinder with respect to the sleeve.

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.
