Abstract

An antitheft system includes a main controller mounted in a car for controlling an overall operation of the antitheft system, and a wireless keypad provided on a front side with numbered keys, and on a rear side with a clip. The wireless keypad may be attached to a car door edge of all versions of different brands of cars via the clip without the risk of separating from the door easily. The wireless keypad also allows a user to enter and transmit a code to the main controller to release or enable the antitheft system just beside the car, and is therefore a humanized design.
