A theftproof system for an automobile includes an elongated slide track mounted on a drive's seat of an automobile, a seat slidably mounted on the slide track, a seat motor mounted on the slide track for driving the sea t to move reciprocally on the slide track, a reduction gear set co-operating with the seat motor to move the seat, and a seat movement control device for operatin g the seat motor to rotate and including a receiver, a central processing unit , a decoder, an actuator, and a motor rotation control circuit. The motor rotati on control circuit is electrically connected to the seat motor for rotating the seat motor, and the seat movement control device is provided with a power supply by a battery and co-operates with an emitter. In such a manner, when the receiver receives a signal supplied from the emitter, the motor rotation control circuit of the seat movement control device actuates the seat motor to rotat e positively so as to move the seat on the slide track to a front end of the driver's seat, thereby blocking and sealing a leg placing space of the drive's seat s o that an extruder cannot step on a pedal of the driver's seat.
