Yes, I would like to receive future marketing communications (such as email) from Caterpillar Inc., its affiliates and subsidiaries worldwide and the Caterpillar dealer network.

Cat® Machine Security System (MSS) is a theft-deterrent system that discourages unwanted operation of equipment by utilizing a unique electronic key or a pass code to start the machine. Traditional Cat keys will not start the machine when Cat Machine Security System is enabled.

The electronic key works by storing a unique identification number that is read by the machine's electronic control module (ECM). The ECM validates the user ID and corresponding key are approved for use and then enables normal machine operation. If the user ID is not recognized by the ECM then the system disables all critical machine functions.
