Abstract

A power tool system includes a hand-held power tool having a motor or a solenoid that drives a tool, and a first memory that stores at least one pass code. A battery pack is detachably attached to, and supplies current to, the power tool and has a second memory that stores at least one pass code. An electronically-actuatable lock and a first controller are provided in the power tool and/or in the battery pack. The first controller reads the pass codes from the first and second memories when the battery pack is attached to the power tool, directly compares the pass codes from the first memory and the second memory, and causes the first electronically-actuatable lock to prohibit or impair operation of the power tool when the pass codes do not match or otherwise correspond in a predetermined manner.
