ABSTRACT:
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority of Korean Patent Application number 2001-26760, filed May 16, 2001.
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a door unlocking system for vehicle, and more particularly, to the door unlocking system in which a switch for simultaneously unlocking the front and rear doors is installed regardless of a door chassis and a key rotor.

Generally, the driver's door includes a switch for transmitting a signal to a central processing unit, wherein the driver inserts the key into the key box and turns the key to one direction to simultaneously unlock the front door and rear door while the driver turns the key inserted in the key box to the other direction to simultaneously lock the front door and rear door.
The prior art (
FIG. 1

10
to be installed rearward the key box
20
.
