Abstract: An improved automobile anti-theft guard plate that provides exceptional strength through the use of two bonded plates. The first plate has a flanged circumference to enclose the second plate. These flanges, especially when combined with the second plate's inherit strength, provide for enhanced rigidity to withstand deformation from a pry bar. An opening through both plates permits the automobile's handle lock activation and door opening mechanism access to these mechanisms within the automobile door. A tower or vertical member on the guard plate extends vertically from the plates and at least partially surrounds and shields the handle's mechanisms to even further dissuade tampering by a thief. The guard plate is additionally designed to permit the handle to be secured thereto through the use of tabs which engage the handle at the same time the handle is engaging the opening mechanism.
