The jack has a round flat plate which rests on the ground when jack is operated to lift the vehicle. It can be remotely operated using push button controls installed in the dashboard of the vehicle. It utilizes the existing hydraulic cylinder provided currently in the vehicle for their operation(s) e.g. the hydraulic systems to operate steering unit or any other devices. The jack system has safety checks—the electrical circuit of the hydroelectric jack does not operate till the emergency brake is applied. An auto lock system ensures the jack will not open accidentally. In case of a car, jack can be installed on to the floor beam inside the body. Jack is firmly placed in the specially designed hole of required diameter. Jack on both driver's and adjoining seat duly balances the weight of the car.
