The invention discloses a keyless two-way induction anti-theft system comprising an entrance guard host and a controller arranged in an automobile. The controller comprises a processor, and a signal receiver, an entrance guard actuator, a power circuit and an alarm connected to the processor. The controller also comprises a signal reference setting device, a signal comparator, an abnormal signal preprocessor, an abnormal signal shielding actuator and an abnormal signal shielding transmitter. The signal reference setting device and the signal receiver are both connected to the signal comparator. The signal comparator is connected with the processor. The abnormal signal preprocessor and the abnormal signal shielding actuator are connected to the processor. The abnormal signal shielding actuator is connected with the abnormal signal shielding transmitter. The keyless two-way induction anti-theft system has a simple structure, is convenient and quick to use, can process and shield abnormal signals and is good in use stability. The anti-theft performance and use safety of an automobile entrance guard are improved to a certain extent, and the applicability and practicability of the keyless two-way induction anti-theft system are high.
