ABSTRACT:
A method and apparatus for decoding locks having a guide member, an alignment member, a reader, and a recording medium, which a guide member is inserted into a lock to open the lock to receive an alignment member which aligns the tumbler members of a lock, thereby permitting a reader to be inserted into the lock, and withdrawn therefrom to cause a displacement of a pivotally connected reader arm which records an image of the lock profile on a recording medium.
