The operating control device can be use on equipment such as hand tools, electronics or fuel pumps. An input device enables the input of user access codes and a readout panel monitors the equipment status. A control member is in communication with the input device, readout panel, power source, driver member and activation member to prevent operation of the equipment by requiring entry of a user code. The control device can include a programmable timer to communicate with the control member to enable the power to flow from the power source to the driver member for a predetermined period of time. A clock can track time and activate and deactivate the timer. The communication can be through electrical wires that can be encased in a solid material to make the control member and wires inaccessible. When used directly on a fuel pump, the control member prevents fuel from reaching the engine without the input of a proper user code. Alternatively, the control device can be a fuel line shutoff valve to prevent fuel from traveling along the line. A solenoid can be used in the shutoff valve to prevent flow of fuel from the gas tank to the driver. A locking driver for use on bicycles interacts with the axle connecting the peddles. A engagement disk, having multiple ports along its circumference, is unmovably affixed to the axle. A locking bar activation member engages and disengages a locking bar with the engagement disk to prevent rotation of the axle.
