Abstract: An automobile steering wheel lock with an alarm includes a lock having a lock core with a chamber containing an alarm and at least one light hole. The alarm consists of a circuit board, a battery, a buzzer and a touch switch. The circuit board capable of sending signals has a warning light and a high-density LED light. Also, a help-signaling device is installed at a conspicuous location of a car and provided with at least one lamp panel. Each lamp panel is provided with a wireless receiver for receiving signals from the alarm and formed of luminescent lamps or LED lamps to show help signals. So, should the buzzer be moved by a burglar, it would sound immediately, spontaneously activating the high-density LED light to radiate toward the driver's seat and the lamp panel lit, achieving multiple anti-theft effects.
