Abstract: An article of manufacture for preventing theft of trailer by unauthorized users after trailers are decoupled from authorized towing vehicles according to the present invention is disclosed. The present invention relates to a device and method for securing a non-motorized trailer from unauthorized movement by attaching a keyed tongue bar to an authorized vehicle and attaching a paired tongue receiver to the non-motorized trailer. If a vehicle does not have attached thereto the keyed tongue, the vehicle, i.e. unauthorized vehicle, will not be able to be attached to and move the trailer. The keyed tongue bar and paired tongue receiver have an abstract-shaped end and matched abstract-shaped opening, respectively.
