Ah, I see what you mean. I'm not sure if your car has a vacuum solenoid in the driver's lock. If not, here is what you will do:

Buy a power door lock motor, position it in the door so that when it goes up, it will lift the driver's door lock plunger. Connect this motor to your keyless entry system.

If you have a vacuum actuator in the driver's door, it makes it easier because you just have to run the wires from the keyless entry system to the vacuum pump.
