ABSTRACT:
Method and apparatus for non-destructively picking locks which normally are operated by keys, such locks capable of having twisting tumbler pins and sidebars. The method requires that: the pins be raised high in the keyway; the plug be axially bored by a thin drill which enters through a low portion of the keyway, the rear end of the drilled bore opening to the bolt cam operator; the drill bit be removed from the bore; and then the bolt cam operator be directly turned to shift open the bolt. This method does not decode the tumblers nor release any sidebar. The preferred apparatus comprises a pin raiser tool, which is self-retaining due to bias on the pins, which is transmitted to the handle of this tool; and a torquing tool, which is passed through the bore and has a blade which seats in the cam operator for turning the operator to shift open the lock bolt. A unique safety shield can be installed on the tailpiece to prevent picking by the method of this invention.
