Remote-controlled automobile and motorcycle lock

A remote controlled automobile and motorcycle lock comprising:

• a U-shaped lock body consisting of a left half body and a right half body combined together, said left and right half bodies having a half female thread at an end of an upper arm, both said half female threads making up a complete female thread when both said half bodies are combined together, said left half body having a small hole in a proper location for an LED lamp to fit in, and said right half body having an opening in a vertical end wall for a lower arm of a hook rod to pass through;
• an electronic device panel fixed with an electronic device including a magnetic switch combined with an inverted U-shaped member at its bottom, a biasing spring being placed between the magnetic switch and the U-shaped member, said inverted U-shaped member being drawn up by the magnetic switch when said magnetic switch is turned on by a signal from a remote electronic controller, an LED lamp fitting in the hole in the left half body and a spring switch to be turned on by a magnet in the remote electronic controller;
• a battery unit in the upper arm in the lock body to supply power to the electronic device;
• a T-shaped cap for closing the end of the upper arm in the lock body to keep the battery unit therein, having a male-threaded stud to screw with the female thread in the upper arm;
• a U-shaped hook rod having an upper rod arm and a lower rod arm extending parallel to each other, the upper rod arm being tubular and shorter than the lower rod arm, said lower rod arm having a plurality of grooves equally spaced apart near a free end thereof, said upper rod arm fitting around the upper arm of the lock body, said lower arm fitting in the lower arm in the lock body, each said groove having a vertical wall near to the free end and a sloped wall far from the free end so that said hook lower arm can be pushed inward in the lock body freely with the sloped walls sliding under two feet in said inverted U-shaped member, but said lower rod arm can be stopped by the vertical wall of any groove when said lower rod arm is pulled outward in the lock body;
• and,
• said inverted U-shaped member being drawn up by said magnetic switch in said electronic device, separated from any of said grooves in the lower arm in said hook arm, allowing said hook arm being pulled out of the lock body in unlocking this lock, when said remote controller sends out a wireless signal to said electronic device contained in said lock body.
