Motorcycle anti-theft device

A theft-deterrent device for a vehicle, comprising:

• a receiver for receiving at least one lock position signal from a remote operation device;
• a processor for determining whether or not an ID included in the lock position matches a stored ID;
• a lock mechanism for responding to the lock position signal when the IDs match to lock or unlock the vehicle;
• an actuator for driving the lock mechanism, and
• a theft-detection unit detecting movement and for generating an alarm signal when the vehicle is moved when the receiver has not received an unlocking signal including an ID matching the stored ID;
• wherein the receiver, processor, lock mechanism, actuator and theft-detection unit are comprised in a module within a single housing;
• and further wherein the primary lock mechanism is engageable with a rotating shaft of a handlebar to lock a vehicle, and the module is situated near the rotating shaft of the handlebar.
