CONSTRUCTION MACHINE CONTROL SYSTEM AND CONSTRUCTION MACHINE CONTROL METHOD

In a method of registering a smart key for construction machinery, a first password is generated in a smart key module mounted in a construction machine. A user setting graphic interface through which a user can input a password, in the smart key module or a user terminal, is provided to the user. The password inputted by the user is compared with the first password in the smart key module to authenticate. An authentication code of a near smart key that is recognized by the smart key module is registered as a new registration authentication code when the inputted password is authenticated.
