Abstract

A system has an electronic key that transmits a coded signal and at least one tool or other device that can receive that signal. The coded signal is compared to a coded signal stored in the tool or other device. If the coded signal authenticates the stored signal, the tool is enabled or disabled for a specified amount of time. An on/off switch then enables the user of the tool to turn the tool or other device on and off during the specified amount of time. After the specified amount of time, the tool is disabled so that the tool or other device can no longer be used. Disabling the tool may be delayed if the tool or other device is in use. The tool or other device may also contain a unique identification code that can be read by an interrogating device to identify the tool or other device.
