The invention discloses a keyless automobile system, including a main chip, a low frequency driving chip, a low frequency antenna and a handle trigger module. The handle trigger module is for detecting whether the vehicle handle is triggered, and outputting a handle trigger signal to the low frequency driving chip when the vehicle handle is triggered; the low frequency driving chip is stored with low frequency wakeup message, and is used for driving the low frequency antenna corresponding to the handle to emit low-frequency wake-up signal when the handle trigger signal is received, and also for sending a main chip wake-up signal to the main chip; and the main chip enters into an awake state when receiving the wake-up signal. According to the keyless automobile system of the invention, the low-frequency driving chip directly reads the handle trigger signal, and completes the wake-up of the key, without communication with the main chip; the wake-up of the main chip accelerates the response speed of the entire system, reduces the total time for keyless entry and improves the user's experience.
