The invention discloses an automobile remote controller, a method for the remote controller, equipment for receiving the remote controller message, a method for verifying the remote controller message and a vehicle. Specifically, the automobile remote controller comprises a keypress; a controller, which is connected to the keypress to detect the message that is corresponding to the keypress and is generated under the circumstance that the keypress is pressed; a transmitting device, which is connected to the controller to transmit the message. The plaintext part of the message includes keypress information, and/or the ciphertext part of the message includes rolling code negation information and/or the checksum of the message. According to the invention, by increasing the information of the message's plaintext part and/or the information of the message's ciphertext part, the safety and reliability of the automobile remote controller is ensured.
