ABSTRACT:
A remote control antifreeze device for a vehicle locking unit comprising a housing with an upper end having a bore centrally formed therein. A slot is formed between the bore and top surface thereof for allowing the bore to be situated about a conventional cylindrical locking unit. Also included is a helical heating element situated in a serpentine configuration within the housing adjacent to the locking unit and further secured thereto. A thin electrical insulator sheath is positioned about a surface thereof. The heating element is adapted to radiate heat energy upon the application of a voltage thereto. A control receiver switch is also situated within the housing. The control receiver switch comprises control circuitry coupled to a power source, a radio receiver element, and the heating element. The receiver control circuitry switch is adapted to allow the application of a voltage to the heating element upon the receipt of an actuation signal manually deployed by a portable transmitter unit.
