Abstract
A working machine management system includes a working machine having a prime mover and a control unit and a key device which is detachable from the working machine and is used for operating the working machine. The key device stores first authentication information for identifying a drivable working machine and second authentication information necessary for the prime mover to continuously operate. When the key device is attached to the working machine, the control unit confirms validity of the key device based on the first authentication information, compares input information from the outside with the second authentication information to determine whether the prime mover can be operated if the key device is valid, and controls operation of the prime mover according to the determination result.
